Title: Montpellier Zac Cambaceres Lot B5
Where: Montpellier, France
Type: Residential
Size: 10,900 m2

With: Studio Gang Architects
Client: Pitch Immo (Pitch Promotion)
When: project on pause
Lot B5 in the ZAC Cambaceres new development area (masterplan by XDGA) is a residential mid-sized block that is meant to house a combination of social, affordable and market-value units.
The Bar Longue Trompe in Montpellier and the genoises eaves all across provincial French architecture were driving our concept inspiration. This project reinterprets and modernizes these shapes/forms in order to create a unique contemporary architecture that is anchored in history. 
The building is also designed to respond to the local climate. The facade is articulated by a set of prefabricated elements (shells) that not only create a 3 dimensional sunscreen for the units but also become  a structural drain for runoff water management. This vertical stacking of ductal shells allows for an economical assembly that offsets the complex geometry of the unique module.

Process  - Carving the box 


01. Generate overall volume. 
02. Identify the Facade area based on urban parameters. North and South Facades must have Loggias. East and West facade-projections should stop above ground level (balcony
03. Carve Volume in Elevation (stepping provide views and green terraces) and in Plan (courtyard apt. get double orientations, a green building requirement)


04. 8 vertical cores. Maximize floor plate efficiency and separate market from social units.
05. Achieve desirable mix. Every floor plate is symmetrical in East-West Axis and has a combination of studios/1bdrs/2bdrs/3bdr/4bdrs in social, affordable and market value range.

Physical Model - Shells and Balconies



Shell module repeats vertically and horizontally. Every column (stack of shells) has either a single(3.80m) or double(7.70m) width module.
There are two types of balconies for units. The shell balconies that are created by the top/bottom flat part of shell geometry and the floating balconies that among other things provide shading for shell balcony below. Shell modules are created by 3 interlocking ductal elements (see below)
