New Social Living Development (Zone 5)
Concept Design In the world of design and urban planning, aesthetics and functionality seem to take the spotlight, especially in how large-scale housing projects are developed. Our aim is to create an organised structure based on thoughtful and parametric methods that will generate personalised housing units meanwhile pushing the modern boundaries of what we consider to be a dwelling. Our mission is to harness the location’s unique potential to create a socially just, economically stable and environmentally responsible developments to build a positive change as to other precedent social housing projects. The results are neighbourhood friendly, integrated developments with a strong sense of belonging and a sustainable community approach as outline in Figure 1 below.

3.0 Location: The sites under consideration for Zone 5 were La Rosa, Grand Bel Air, Mare D’Albert, Britannia, Tyack, Souillac and Surinam as earmarked in Figure 4 below.
Figure 4: Location Plan of Zone 5 Sites All these sites were found to be bare land and adjacent to existing pockets of residential land use such as recent VRS morcellements and NHDC development, thus falling under the boundaries of allowable growth zones as per zoning plans of concerned District Councils of Grand Port and Savanne. La Rosa, Mare D’Albert and Grand Bel Air are also zoned within regions affected by the Department of Civil Aviation (DCA) regulations.

4.0 Building Configuration: Unit Types: As outlined in the aims of the project of the Client, we designed 3 unit types of carpet area 60, 65 and 75 square metres who are name M1, M2 and M3 respectively. An alternative layout for the M3 unit type has been provided suitable for the physically challenged persons as M3 units are always on the ground floor level on the G+1 G+2 and G+3 Apartment Blocks. As for the G+6 block, the presence of lifts allows access to the upper levels for the physically challenged persons. Apartment Block Types: As just stated, there are 4 apartment block types as per their varying height levels as stated previously: G+1, G+2, G+3 and G+6. The table in Figure 6 below summarises the number of units per block types and the repartition of the units.

4.5 Apartment Block Massing
For massing of the building envelope, we have 4 units per floor connected by a centrally located circulation space. There is an interplay over the laying of the rooms so as the floor above have access to terraces.
