Architectural Intent & Site StrategiesThe Cranbrook Wellness Center connects the east and west sides of the campus through the Grand Allee. With the roundabout being the new, most used, entrance to the campus, the undeveloped portion in the middle pro-vided an opportunity for development, formally and functionally.
Taking the main routes from the Natatorium form the west and the musuem to the east, a boundary is created on the site.
Upon analyzing the campus, public space is highly open, and provides a “field” of free circulation and a high degree of interaction. Therefore, smaller nodes are dug out at the driplines of the surrounding trees, and paths, playing off of the cant from the Natatorium, connect the nodes, providing smaller scale public spaces, which also break down the Grand Allee in scale.
Architectural Intent & Site StrategiesWith the program housing visiting scholars and artists and a spa, a duality is created. The guests staying in the building are for the campus, while the general visitor to the building is there for the spa services. With the Nata-torium and musuem placed to the northern edge of the campus, the northern edge becomes the broundary for visitors into the Cranbrook campus, logically placing the spa to the north of the site, where it can formally take on a distinct shape and become a foroeign object to the campus. The hospitality portion, however, will take on the context of the campus and be the southern, public face of the building.
With the paths dug, formal bounding conditions are created for the spa portion, which is privitized on be being on high ground, and can then be open to the trees and outside with a curtain wall. Beams tie the spa to the box to the south, and they stack upon another to create extra rigidity.

Code: FireFire Code Worksheet SEC Tech 2(Based on International Building Code 2000)
The purpose of the fire code worksheet is to develop the parameters used in determininglevels of protection within the building and means of egress.
Describe Building Use Group: Assembly Group AUse Group Code: A-3
I. Building Height. Number of Floors, and Building Area. In order to determine these values you must first establish the "Finish Ground Level" and the "Grade Plane." The finished ground level is a horizontal plane drawn through the average finish grade surrounding the building. Draw a schematic of the building. For each face of the building, find the average level of the ground. To find the average of these values: Multiply the elevation by the length of the facade; sum these products; then, divide the sum of the products by the sum of the facade lengths.
Side Length Elevation at Face Length x ElevationN 117’ 864’ 101088 sqftE 118’ 866’ 102188 sqftS 91’ 864’ 78624 sqftW 170’ 862’ 146540 sqft
Sum L = 496’ Sum(elev x L) = 428440 sqft
Elevation of Finished Ground Level = sum (elev x L) I sum(L) = 863.79’
The grade plane will differ from the Finished Ground Level if the ground slopes away from the building, within the first 6 feet. To determine the Grade Plane, find the lowest ground elevation from the edge of the building to a perimeter 6 feet away (or to the lot line if closer than 6 feet.) Fill in the chart as above using the new elevations.
Side Length Elevation at Face Length x ElevationN 117’ 861’ 100737 sqftE 118’ 865.5’ 102129 sqftS 91’ 861’ 78351 sqftW 170’ 862’ 146540 sqft
Sum L = 496’ Sum(elev x L) = 427757 sqft
Elevation of Grade Plane = sum( elev x L) I sum(L) = 862.41’(Elevation of grade plane=finished ground level if site does NOT slope away from bldg.)
Height of Building = vertical distance from grade plane to the average elevation of thehighest roof plane = 25’
Code: FireBasement Yes or No? Does the basement count as a floor?If the building has a portion below grade, it may have to be counted as a separate floor.The building has a "basement as a floor' if any of the following statements are true. Ifany of these conditions apply, count the basement as a floor in the total number of floors.a. First floor elevation is greater than 6 feet above grade plane Y or Nb. First floor elevation is greater than 6 feet above finished ground level for more than50% ofthe building perimeter Y or Nc. First floor elevation is greater than 12 feet above finished floor level at any location.Y or NIf yes to any of these, count the basement as a full floor. If there is more than one levelunderground, count each as a full floor.Number of Floors: 2
Building Area: determine the maximum projected area covered by roofs or any floors.Building Area= 7832 sqft
Height, Number of Floors and Area Modifications The building codes allows for increased allowable areas, heights and number of floors based on two conditions: use of sprinklers and street frontage.
Area Increase due to Street FrontageDetermine the percentage of the building perimeter that faces a street. In order to qualify for street frontage increases a building must have at least 25% of its perimeter facing a public way with a minimum width of 20. If the width of the public way is greater than 30 feet, limit W/30 to 1.0. The Increase factor is given by:
𝐼𝐼𝑓𝑓 = 100 ∗ �𝐹𝐹𝑃𝑃 − 0.25� ∗
𝑊𝑊30
Where F = frontage length (ft.)P = entire building perimeterW= width of public wayI = percentage of area increase allowed
F = 117’ P = 496’ W = 21’
𝐹𝐹𝑃𝑃− 0.25 = -
0.014 If= -0.988 0
Area Increase due to SprinklersIs= 200% for multi- story buildings or 300% for single story buildings
Combined Increases Due to Frontage and Sprinklers
𝐴𝐴𝑎𝑎 = 𝐴𝐴𝑡𝑡 + �𝐴𝐴𝑡𝑡 ∗ 𝐼𝐼𝑓𝑓
100 � + �𝐴𝐴𝑡𝑡 ∗ 𝐼𝐼𝑠𝑠
100 �
Where At = tabulated Area per floor (Table 503)Aa = allowable Area per floor
Code: FireThe total area per floor is given by the equation above. This equation can be modified by dividing all expressions by Aa. This will yield a factor that can be used for any allowable area independent of the construction type.
Area factor = 1 + � 𝐼𝐼𝑓𝑓100�+ � 𝐼𝐼𝑠𝑠
100�
Area Factor = 1 + � 0100�+ �200
100� = 1 + 0 + 2 = 3 (includes sprinklers)
The Area factor exclusive of sprinklers can be calculated from the following formula. This factor will be useful in determining whether sprinklers are necessary for any construction type.
Area Factor = 1 + � 𝐼𝐼𝑓𝑓100� = 1 + 0 = 1 (excludes sprinklers)
Allowable Heights and Building AreaUse Table 503 to determine the allowable Building Heights (number of stories) and allowable area per floor as follows. Determine Use Group. Determine possible construction types and enter the tabulated area Aa for each. Start with the most restrictive construction type (usually far right) and proceed until you find a construction type that allows the area and height of your building. Calculate the Allowable Area for each by multiplying by the Area factor. Calculate the area factor exclusive of sprinklers and inclusive of sprinklers. Compare the modified Allowable area with the area of one floor. If the allowable area is insufficient then increase the construction type (move left) or add sprinklers.

Code: EgressThe initial building only had one means of egress on the top floor, the fire protected exist to the east. Therefore, a bottom floor to the library was added, making the libary a more dynamic two story space.
Since the spa area is quite winding, and sits on elevated earth, the outdoor meditation areas are isolated and do not provide safe refuge. The plaza to the west, however, becomes stadium seating for relaxation, and elevates the plaza to a level where occupants may exist through a fire exit in the event of an emergency.

An elevator at the Southwest corneris the acces-sible connection between the �rst and second �oors in the bar portion of the building.
Although the building has several elevational changes on the �rst �oor, accessible slopes of 1:12 are used to transition from di�erent �oor heights.
All corridors are atleast 60” wide.
The elevator to the southwest create an accessible route between the first and second floors. The elevator also helps bound the front courtyard of the building.
With the first floor being a series of ramps which increase the elevation of the floor as the building sprawls north, careful attention was put into the ramps being completely accessible and in compliance with code.
Code: Accessibility
Structures The structural system of the bar is fairly typical, being a steel frame with brick, stone, and wood veneers as ap-propriate to blend in with the campus and create respective spa and hospitality environments.
With spans up 60’, beams in the spa are 3’ deep a piece. The stacking of one system to another helps provide extra rigidity in the system to resist both lateral and gravity forces. Small columns on the perimeter of the building do help hold up the roof and curtain wall, but primarily act as attachment points. At the center of the intersection of the two beam systems, three large columns draw in forces from the beam. The columns mark the entrance of the therapy pool space and bear their force into the foundation through the pools to create a dramatic effect.

Environment: HVACThe building is zoned into three parts. The brown is the dry program, which includes the lobby, administration, library, and residences. The are supplied by a VAV system.
The purple is the wet program, which contains all the pools and massage spaces. Though radiant flooring is used, duct work for the 6 air changes an hour are still required.
The green is the studio space, which has its own heat pump.
Since path have been dug around the building, creating an elevated platform, the mechanical equipment can be placed directly underneath the building during the initial construction process. They can then be accessed from the paths as well.
The bottom blue areas are the mechanical spaces for each respective zone. A thick floor houses all the ductwork for the top floor of the dry program as well. Intake can then easily ben taken from ground level, providing cooler air in the summer.
Since the spa utilizes a double curtain wall, the in-ner space is where exhaust can be vented, which fur-ther prevents heat loss in the winter. Along the top of the double curtain wall, as outlined in red, exhaust vents can be integrated into the system.

Environment: Passive & Daylighting
Environment: Passive & DaylightingWith the spa area being enclosed in a curtain wall, daylighting is easily provided. An overhanging roof, along with the thick mass of trees enclosing the norther portion of the building provide shading. The double curtain wall, with the air between the two layers, helps vent away excess heat in the summer as well.
Roof overhangs allow winter sunlight to penetrate and heat the building, while blocking summer insolation. Stone bricks used for walls and flooring become a source of thermal mass to help prvent termperature swings.
