Tianjin Green Triangle

TOD Place Making with 8 Design Strategies

Serge Salat Architect

The World Bank seminar on TOD, Tianjin, June 2014

VALUE CREATION

1. High FAR 2. Connected 3. Streets and Public Spaces

as Places for People 4. Low and Medium Rise

Small blocks 5. Mixed Use

1. Imageability 2. Enclosure 3. Human Scale 4. Transparency 5. Complexity 6. Coherence 7. Legibility 8. Linkage

Through Planning Through Design

TOD Challenges and opportunities in China - Increase Densities around Transit Hubs - Shift from Superblocks to Small Blocks - Develop Connectivity - Create Public space - Increase Walkable Accessibility - Increase Mixed use, Variety and Flexibility

Golden Triangle Park is an asset for the 250,000 people leaving in a radius of 2 km (very high density of offices) It should become a destination and a civic space for this community Environmental benefits: heat island effect reduction Social benefits: creates community civic space Economic benefits: increases property values around the park

EFFICIENT LAND USE Perimeter block development reaches a FAR of 4 with medium rise buildings and 50 % of land for inside green civic space Serge Salat, Architect.

GREEN TRIANGLE Serge Salat, Architect.

A green preserved island in a highly dense neighborhood Preserve Green Space entirely : more green space than before thanks to suspended gardens, green roofs and terraced gardens. 50% of the park is preserved at ground level; More than 50% is recreated in the form of elevated gardens.

GREEN ELEVATED MOVEMENT SPACE Serge Salat, Architect.

LINKAGE refers to

physical and visual connections from building to street, building to building, space to space, or one side of the street to the other – that tend to unify urban space. Serge Salat, Architect.

Linkage: Recreating vibrant street edges Above: source ITDP. Below: Serge Salat, Architect.

GREEN CIVIC SPACE Green Plaza and green amphitheater are astounding civic places Serge Salat, Architect.

CIVIC SPACE A Green Agora provides space for performances and people gathering. Serge Salat, Architect.

CONNECTED : Transport Node - BPS and subway lines are connected by a pedestrian

lane through public garden. - 6 public passages allow crossing the garden from

adjacent streets and move towards the river. - Green roof promenade will be extended at second

stage towards the commercial street and will replace the existing overpass.

Increasing linkage Source: ITDP

LINKAGE: A continuous green promenade for pedestrians on the green triangle roofs

links all spaces (inside and outside) with elevated gardens and bridges sloping gently up and down from street level to the tower

LEGIBILITY: refers to the ease with which the spatial structure of a place can be understood and

navigated as a whole. The legibility of a place is improved by a street or pedestrian network that provides travelers with a sense of orientation and relative location, and by physical elements that serve as reference points.

Serge Salat, Architect.

CONNECTED: Green elevated gardens Serge Salat, Architect

IMAGEABILITY An iconic green tower -Landmark (singularity and location) -Sense of place: a characteristic visual theme -Serge Salat, Architect.

COMPLEXITY And Transparency People can see what lies beyond the edge of streets and public spaces Serge Salat, Architect.

COHERENCE: Rhythm of street edge (vibrant and green) Medium rise buildings line the street providing a coherent and vibrant streetscape Serge Salat, Architect.
