Timber Frame during the construction and completion phasesTimber Frame during the construction and completion phases



TEXT PAGE THREETEXT PAGE TWO

t Cons truction— The Sigma home embraces a hybrid approach to the application of

different leading-edge offsite technologies. The smarter build processenabled the construction of two semi-detached four storey structuresin 8 weeks from commencement to completion, compared to thetraditional timescale of 24 weeks.

t Fas t -f ix Foundations— Roger Bullivant ‘System First’ modular foundation system enables

minimal site excavation with pre-cast piles and beams. From bare siteto completed foundations took just 5 days. The system delivers a U-value of 0.18 W/m2K.

t Advanced Closed Panel Timber Fr ame Walls— The Sigma home’s external fabric utilises the Stewart Milne

Generation 3 closed panel system which provides a U-value of0.15W/m2K. The build up comprises 140mm solid timber studwork,0.035W/mK glasswool insulation between the studs and sheathedwith 9mm OSB/3 boards on both faces. The inside face utilises TyvekAirguard vapour control barrier and Illbruck taping systems. 25mmservice battens at 600mm centres completes the internal build upand is ready for services and dry lining.

— The external face is clad in standard breather membrane, andcompletes the construction which is manufactured in the factory andcrane erected as large panels on site.

— The external render is fixed directly onto a recycled backing board,vented cavity and Celotex insulation system.

— The timber cladding features utilise Finnforest thermowood rainscreen cladding with a service life of up to 30 years.

— The internal face is finished with two layers of plain plasterboardproviding one hour fire performance, eliminating the need for firedoors and fire protected stair enclosures.

— Nordan ‘N-Tech’ triple glazed high performance timber windowscomplete the external wall construction and contribute to an overalltargeted air tightness of 1.0m3/(h.m2).

t Floor Casse ttes— The Sigma Home uses a combination of three different

pre-fabricated timber based floor systems to demonstrate the rangeof options available from Stewart Milne Timber Systems. The upperfloors all utilise an underfloor heating system to service the spaceheating requirements, negating the need for space restrictingradiators and therefore enabling further flexibility. The build up ontop of the structural deck ensures that finished floors are laid in dryinternal conditions, and in addition provides enhanced acousticvalues of circa 2-3dB to reduce noise transfer through the floors.

— Stewart Milne Group’s dB-50 acoustic floor system is designed overthe live/work/play unit to compartmentalise multi-occupancy livingspaces. The system utilises a special design of acoustic joist whichdelivers enhanced sound transfer performance equivalent to RobustDetail levels. The floor system incorporates an integral service voidwhich requires no horizontal overhead drilling or notching of thejoists, making easy the installation of services or future access formaintenance or upgrading.

— The floors are designed to clearspan from gable to partywall givingtotal flexibility of living space. Floor to ceiling heights are designed to suit standard plasterboard and OSB sheeting sizes, eliminating the need to cut sheets and utilising standard timber stud heightcomponents. This reduces production and build costs and simplifies manufacture.

t R apid Roof Sy s tem — The design of the Sigma Home enables simplified roof construction

with factory made roof cassettes and utilises the roof space to createan internal vaulted feature. This enables the roof to be wind andwatertight very quickly. The pre-insulated closed roof cassettes arefactory produced with factory-fitted roof membrane and airguardvapour barrier to the ceiling side. Factory installed insulationcontributes to an overall U-value of 0.15 W/m2K. On this project sixroof modules were installed in less than three hours.

— The roof cladding system is a preformed zinc metal system the fixingpoints for which are designed into the roof cassette.

t Pod and Panel Hybrid Technologies— Pre-fabricated bathroom pods supplied by Offsite Solutions were

delivered in sequence to suit the timber frame erection process andcraned into place on site. Each pod incorporates low waterconsuming items and includes an Eco-play grey water recyclingsystem as noted previously.

t Supply Chain Integr ation— Stewart Milne Group has developed excellent partnerships with key

suppliers over its time in business and these have been central to theSigma Home project, leading to efficiencies in time and cost, andproducing an enhanced end solution.

t Safe ty and Security— The structure includes an automatic fire detection system together

with sprinklers.— Designed primarily for urban locations the properties are to ‘Secured

by Design’ standards, with particular emphasis on ensuring externalpublic spaces are overlooked by the principal internal rooms.

t Health and Safe ty— The design and build of the Sigma Home has a number of health and

safety features built-in as the result of extensive health and safetythinking during the design process. Early identification of principalbuild components and hazards, and the adoption of CDM principles,work hand in hand with offsite technologies to deliver a safetyconscious project and safe working environment for site operatives.

T h e S i g m a H o m e


The Sigma Home constructed at the BRE, Watford, is one of thecountry’s first five star rated homes under the Code forSustainable Homes. Presented as two semi-detached homes, one is fully finished and furnished as a three but potentially a four bedroom four storey townhouse to illustrate practicallyhow such an innovative design can contribute to contemporarylifestyle. The other is a ‘blank canvas’ to highlight the technologyand the flexibility to produce different layouts. In this case a ground floor, one bedroom apartment/live-work unit with a three storey, three bedroom triplex above.

The Sigma Homes also benefit from a co-ordinated approachusing Modern Methods of Construction (MMC), one of the mosttechnologically advanced and sustainable forms of constructionto satisfy the demands of Egan led methodologies and recentGovernment directives.

t Urban Des ign— The Sigma Home is envisaged as a semi or terraced property forming

semi-continuous urban frontages with associated car parking – inlandscaped boulevard or courtyard settings, responding to the CABEagenda of ‘Building for Life’.

— Several different variants can be produced, with different layouts,elevations and finishes.

— This demonstration house is externally finished in a combination of high performance insulated acrylic render system and timber cladding.

t Layout Des ign— The Sigma Home is a contemporary update of the traditional 3 storey

townhouse. Arranged over 4 levels to minimise the building footprintand to maximise affordability, the split-level house adopts a semiopen plan format suited to today’s informal lifestyles. Daylight isplentiful and the circulation core feature adds views andcommunication between spaces. Flexibility is integral to the house,which has been developed in conjunction with PRP Architects to‘Lifetime Homes’ standards. Key to its design is the ability to separatethe ground floor from the upper floors to create a self containedapartment or a home office (thus reducing carbon emissionsassociated with travelling to and from work).

t Energy— The Sigma Homes utilise renewable energy by way of heating hot

water from solar thermal and photovoltaic roof panels, roof mountedwind turbines and solar gain.

— A solar stack and ‘whole house’ mechanical ventilation and heatrecovery system controls temperature in a passive system. The stacksits centrally above the stairwell and sucks in warm air as it rises, in a similar way to that of a chimney. A heat sensor opens and closes a vent at the top of the stack to manage the optimum temperature in the building.The high levels of insulation provided by the wall, floor and roof elements are coupled with high performance timber windows to give excellent thermal performance of the external envelope. Addto this the airtight construction and detailing, ten times better thancurrent Building Regulations requirements, the resulting designdelivers energy performance 100% better than Part L1A.

— All timber and timber products are from managedsustainable sources.

— All of the homes’ internal, external and security lighting (excludingthe pod) is low energy and white goods are all A+ or A rated.

t Water— An in-built Eco-play grey water recycling system reclaims shower and

basin water for toilet flushing. All showers, taps and washingmachine have low water consumption.

t Was te— In addition to the waste bin, three 7-litre internal bins are in

cupboards and out of site, holding recyclable waste.

The Sigma Demonstration House achieves Level 5 compliance under the new Code for Sustainable Homes. The Sigma Village proposalsdemonstrate how Level 6 can be achieved in anexpanded development context.

Level 5 compliance – key featurest Carbon neutr al

The house is designed to be carbon neutral interms of space heating, hot water, lighting andventilation fans. High performance insulationand triple glazed windows make it a highlyenergy efficient design. The house also includesother carbon reducing measures such as lowenergy appliances, high efficiency condensinggas boiler, a home office and cycle storage toreduce car travel.

t Low water useWater saving devices will be used throughout –washbasin, bath and shower water is collected for flushing the toilets. Water usage is intended to be kept below 80 litres per person per day.Water butts will be provided to collect rainwaterfrom the roof for watering the garden.

t Fle x ible des ignThe house is designed with an open-plan layout to suit modern lifestyles. A central core containsbathrooms and other highly serviced areas alongwith the stairway, which provides verticalcirculation. Floor plates are connected onto thiscore, allowing a flexibility of sizes and uses of space. This also allows the home to change overtime along the principles of Lifetime Homes. Theadjoining house has been built to show how itcan be easily converted to a one bedroom flat orwork unit on the ground floor and a 3-bed houseabove. The house is split-level, which givesinterest to the spaces and high ceilings on theground floor; this also keeps the circulation to aminimum, which is required on this tight site. Theopen plan design also allows views, daylight andventilation across the levels. Safety and security is enhanced by using a domestic sprinkler systemcombined with fire and security alarms.

t High densityMaximising family living in city centres isessential for true sustainability and we believethat this four storey family home usessignificantly less land than a traditional four bed home, making the proposal more affordableand in line with Government's current thinkingon increasing housing density.

Level 5 compliance –key features (cont.)

t Energy s tr ategy— Increased levels of insulation 'U' value

of walls, roofs and ground floor of<0.15W/m2K 'U' value of triple glazedwindows 0.7 W/m2K.

— Airtight construction (designed toachieve less than 1.0m3/(h.m2).

— High efficiency whole houseventilation and heat recovery system,fresh incoming air recoups heat fromthe extracted air.

— Careful use of solar gain.— Solar Collectors on the roof of the solar

chimney preheat the hot water cylinder.— Wind turbines attached to each house;

exporting electricity to the national grid.— Photovoltaic panels offset the

remaining CO2 associated with spaceheating, hot water, lighting etc

t Solar chimne yOn the roof of each house is a solarchimney positioned above thestaircase. The roof is orientated southat 36˚ from the horizontal to allowmaximum solar gain for the solarcollectors positioned on it. The north-facing window allows daylight intothe stair and ventilation of hot air outin the summer. By using the stackeffect in the stair core, we can drawair through the house for cooling.

t Other features— Careful selection of materials.— Airborne sound insulation values that

are at least 8dB higher than theBuilding Regulations.

— Ecological enhancement of the site.— Internal and external recycling

facilities.— Compost bin.— Best practice construction

management in reducing waste, lowenergy usage and recycling.

— Smart technology will providemonitoring of water and energy inuse; the construction water andenergy will also be monitored.

— Designed to Secure by Designstandards.

— Extensive outdoor spaces have beenbuilt into the design at upper levels.

— Minimal requirement for wet tradeson site, speeding up the build process.

t Zero carbon des ignLevel 6 requires zero carbon design – i.e. over and above the level 5requirements, the offsetting of electricalloads for all domestic appliances. Thisrequires additional onsite electricalgeneration which could be achievedeither by high efficiency roof mountedphotovoltaic panels or large scale windturbines.Our level 6 proposal assumes communalbiomass heating supply and theomission of the small-scale wind turbinesin consideration of the increased PV orlarge-scale wind outputs.

t Improved ecologyscoringThe exhibition house scores poorly inthis area of the code assessment dueto particular constraints of the BREsite. Level 6 compliance would requireimproved scoring, which might beachieved through, for instance,through the remediation of abrownfield site or by delivering specialecological enhancements.

Level 6 compliance – The Sigma Village

The demonstration house has been fully assessed on the basis of the asbuilt conditions for one house on site at the BRE. Level 6 compliance wouldrequire two significant adjustments to the Code assessment;

A G u i d e d T o u r

S i g m a I

The Sigma Home I is a 4/5person open plan, splitlevel townhouse which isfitted out as a showhouse:

Entrance areat Glazed entr ance screen

Entrance to The Sigma I Home isthrough a high performance tripleglazed entrance screen which providesa large amount of daylight into theinterior and also permits passivesurveillance of the external publicrealm to help create a safe and secureenvironment. The timber glazedscreen, along with all windows in the house, is triple glazed and argonfilled and achieves an impressive U value of 0.7W/m2K.

t Informal l iv ing space The front entrance opens into aninformal family living space with a 11⁄2 storey ceiling height, and which hasviews through to the rear of the houseand also up to the formal living area atfirst floor level, which is open plan tothe ground floor. The house layout isdesigned to suit contemporary,informal lifestyles and provide aninnovative, dramatic interior space.

t StairA feature of the house is the opentread stair manufactured fromsteamed beech, which was designedand assembled within the StewartMilne Timber Systems factory. The stair was craned into position duringthe structural timber frame erectprocess, and was fitted withtemporary treads during the house fit out to avoid damage.

t CloakroomThe cloakroom is designed to LifetimeHomes standards, which allowssufficient space for the fitting of ashower by occupants at a later date ifrequired. The sanitaryware is from theWhite and Silver range by IdealStandard. Pressure limiters are fittedto the taps to minimise unnecessarywater consumption.

t Under s tair s cupboardThe cupboard houses the hub for thecategory 5 wiring system, whichfacilitates a network for computersand entertainment systemsthroughout the home, along with theinfrastructure for a buildingmanagement system.

through to:

Kitchen/Dining room t Kitchen layout

The layout incorporates an informalcoffee bar area as well as space for a dining table, and is arranged onopen plan with the family living roomwhich allows for a bright interiorregardless of the building orientation.Access to the rear garden and deckarea, along with the external recyclingstore and bicycle store, is from therear kitchen door.

t Kitchen specif icat ionThe lacquered kitchen units aremanufactured in Germany by Nobilia,and incorporate a concealed recyclingfacility beneath the kitchen sink.A high efficiency gas boiler isconcealed at high level within the tall larder unit of the kitchen.

t Kitchen appl iances Highly energy efficient appliances havebeen specified in terms of both energyconsumption (A and A+ rated) and alsowater consumption (the dishwasheruses 10 litres of water per cycle, thewashing machine uses 40 litres). The kitchen tap is fitted with a flowrestrictor to minimise wasted water.

t Fire strategyKey to allowing the open plan layoutdesign has been the engineered firestrategy to ensure occupant safety in the event of a fire, to at least theequivalent of Part B BuildingRegulations. There is an automatic firedetection and alarm system to warnoccupants of a fire incident, and alsoa system of sprinklers to quench anyfire detected. This is to replace thetraditional smoke detectors and firerated partitions and doors.

t Passive ventilation strategyThe open plan layout within theground and first floors allows thecross flow of fresh air through thehouse from openable windows onboth levels, as well as funnellingwarm exhaust air up through the open stairwell to the ‘thermallantern’ at roof level where it isdispelled through an automaticallycontrolled window.

upstairs to:

Study/additionalbedroomt Layout concept

The study is intended as a bright room with views over the street below to create an attractive workingenvironment. The extent of naturallight reduces the requirement forartificial lighting during the day.Artificial lighting throughout thehome is provided by recessed lowenergy downlighters.

t Floor f inishThe Faenza Clip Tile floor finishthroughout the house is a dry fixinterlocking ceramic tile whichrequires no adhesive or grout and significantly speeds up the fit out period on site as a result.

upstairs to:

Bedroom 2t Layout concep t

The window configuration allows forthe possible subdivision of bedroom 2to form two single bedrooms (by fittingan additional door from the hall),which along with the master bedroom,and potential use of the study asanother bedroom would create a 4 bedroom townhouse.

t Wall f inishThe walls are finished with NutshellSuper Eco emulsion which is amicroporous, biodegradable andvirtually odour free paint, and can betinted with earth & mineral pigmentsto give a variety of natural hues.

Family bathroomt Bathroom Pods

The steel framed bathroom pods weremanufactured and finished off site byOff Site Solutions. The finished podswere craned into position during thetimber frame erect process, and savedtime for finishing trades on site whilstachieving high quality standards in afactory environment.

t Heat recovery sys temExtracts for the mechanical ventilationsystem are fitted to wet areas such asbathrooms, which extract warm,moist air to a heat recovery unitwhere the heat is transferred to pre-warm fresh incoming air, which isthen supplied at low pressure tohabitable rooms.


Services distributioncupboardt Services

Adjacent to the bathroom pod (and ensuite bathroom pod above) is the main services riser and cupboard,which houses the heat recovery unit,the drainage runs, the hot watercylinder and the manifold for theunderfloor heating system.

t Solar thermal panelsThe black elliptical pipework is thesupply and return pipework whichgoes to the roof level solar thermalpanels, which preheat the hot waterfor heating and domestic use andthereby reduce carbon emissions fromthe boiler. Solar thermal panels areamongst the most efficient and costeffective of microrenewable energytechnologies currently available forthe domestic market.

upstairs to:

Sun terracet The generous sun terrace is located at

a high level within The Sigma Home toprovide a calm, external retreat awayfrom potential noise at street level,and to maximise the exposure todaylight free from overshadowing bysurrounding buildings that can occurin high density urban locations.

upstairs to:

Landingt The thermal lantern located above the

top floor landing is an integral part ofthe passive ventilation strategy for TheSigma Home, allowing for the exhaustof warm air when required, by means ofthe natural ‘stack effect’. The window inthe lantern is controlled automaticallyas climatic conditions dictate.

Master bedroomt Layout

The master bedroom is positioned at the top level of the building toincrease the privacy and quiet for The Sigma Home’s principal owners/occupiers. The master bedroom has its own private external terrace andensuite shower room, which is similarto the family bathroom below it inthat it was manufactured off site as a steel framed pre-finished pod andcraned into position.

t Roof sys temThe ceiling is vaulted to increase thefeeling of space in the room, and as aresult of the use of the Stewart MilneTimber Systems cassette panel roofsystem above, rather than traditionalroof trusses which can create deadspace in the roof zone.

t Electric ity In ver tor sLocated within the closet of themaster bedroom are the invertors forthe roof mounted Swift wind turbinesand the photo-voltaic panels, whichare roof mounted and also arrayed onthe external gable wall of the Sigma IHome. The photo-voltaic panels andthe wind turbines produce electricityfor the house. Along with the solarthermal roof panels which pre-heathot water for the domestic hot waterand heating systems, thesetechnologies offset by 100% the CO2emissions that would otherwise begenerated by the home, and are oneof the principal elements in allowingThe Sigma Home to achieve a 5 starrating in the Code for SustainableHomes. The wind turbines can beviewed from the external terrace.

through the door in the party wall to:

S i g m a I IThe Sigma Home II is a flexible 3 bedtriplex home with the same footprintand shell as Sigma I, which isdemonstrated here with the groundfloor as an integral work space. Thereis also the option to completelysubdivide the ground floor and createan additional Sigma III unit, whichwould be either a stand alone officespace or a compact starter flat. This is intended to give occupantssome future flexibility and a potentialincome stream from the ground floor,as well as possibly assisting first timebuyers onto the property ladder.

Master bedroomt Par ty Wall

A portion of the plasterboard hasbeen omitted from the party wallaround the pass door used to enterthe Sigma II house. The party wallconsists of two leaves of timber framewalling and meets the fire andacoustic levels of Robust Detailsstandards.

t Floor cons tructionPlease refer to the cutaway panel inthe floor highlighting the StewartMilne Timber Systems dB-50 acousticfloor system, which is designed toachieve Robust Details levels ofacoustic performance between flats,but without the need for a secondaryceiling void for services, or a floatingfloor construction.

t Air t ight cons tructionPlease refer to the cutaway panel in the window sill highlighting theairtight construction techniques usedthroughout the homes, which achievean impressive airtightness value of 1.0 m3/(h.m2), and reduces heat lossthrough the building fabric.

t Heat recovery unitLocated at high level and left exposedfor exhibition purposes, a heatrecovery unit transfers heat energyfrom warm exhaust air to pre-heatincoming fresh air as in The SigmaHome I.

The system is self monitoring,and stores grey water for a maximumof 24 hours before purging the system,to ensure that hygiene standards arenever compromised.

Services cupboard/risert The services cupboard contains

the manifold for the underfloorheating system, and also the hotwater cylinder

Bedrooms 2 and 3t Layout

Bedrooms 2 and 3 are both singlebedrooms. Bedroom 3 contains two cutaway panels as follows:

t External wallcons truction Please refer to the cutaway paneldescription for the wall build up whichis based on a 140mm timber frame.An innovative prototype product isbeing trialled within some of TheSigma Home walls, an 8mm thickpanel manufactured by Dupont,which is located behind the doublelayer of plasterboard and acts as astore for thermal mass to limit heatbuild up internally within the homeduring hot weather. The Energainboard changes its inner propertiesfrom semi solid to semi liquiddepending on heat gain, thus storingenergy for release at night whentemperatures drop. Also of note is theabsence of the traditional outer skinof concrete blockwork within the wallbuild up, with the use instead of acombination of sustainable timbercladding and a Sto thermal rendersystem as used extensively throughoutEurope. This approach speeds up thebuild process on site.

t Floor cons tructionThe floor cutaway demonstrates the Stewart Milne Timber Systems I beam acoustic separating floorsystem, suitable for reducing noisetransfer between properties to RobustDetails standard.

downstairs to:

S i g m a I I IAs demonstrated here with the groundfloor as an integral work space, theSigma III unit is wholly integrated intothe Sigma II home above. There is alsothe option to completely subdivide the ground floor and form Sigma III as an independent unit, which wouldbe either a stand alone office space or a compact starter flat. This isintended to give occupants somefuture flexibility and a potentialincome stream from the ground floor,as well as potentially assisting firsttime buyers onto the property ladder.Please refer to the graphic panelsshowing the possible layout optionsfor the ground floor.

t Underfloor heatingsys temThe cutaway panel in the floor showsthe underfloor heating system, which is a wet system embedded withininsulation placed on top of the floorslab, thus directing the heat upwardsthrough the floor finish. Underfloorheating is a highly efficient heatingsystem as it operates at a lowertemperature than conventionalradiator systems and provides radiantheat rather than convective heat. Thereare clear marketing benefits in havingno radiators on walls which frees upspace within homes and allowsfreedom in furniture placement.

t Energy usage monitor panelA prototype version of a userawareness system for energy usagewithin the home is shown, wallmounted, towards the rear of theSigma III layout. The EWGECO panelmonitors and displays the energyusage for Electricity (E), water (W)and gas (G) and advises the buildinguser accordingly, which will likely lead to a reduction of the energy load through behaviour change.
