The building is solved with a single vertical communications hub that connects the upper floors.
On the first floor are arranged four identical dwellings, two street-oriented and two backyard, all with private terrace, bedroom and living area of 31 m2. On the second floor are arranged three units, two of which are identical to those of the first floor and a third bigger unit with 2 bedrooms and a living area of 61 m2 in total.
The dwelling floors are solved with a central “dark core” of access formed by the common elements of access and services and housing lobbies so that, peripherally arranged rooms, kitchens and bedrooms with direct natural lighting.
This disposition enables a major rationalization of facilities (mostly centralized) in their paths, entrances to homes and arrangement of the control mechanisms and reading private consumption.
The design prevails passive systems over active systems for the control of energy balance sheet, water consumption and health surveillance of users.

Owner approach of sustainability
The public housing promoter understands that building sustainability must be part of the product offered to the society. In particular, energy and water vectors are treated systematically in almost all of the buildings promoted by PUMSA, assessing what the consumption can mean savings for users of public housing. The social and environmental approach must always be linked to the economic approach so that sustainable building is not more expensive than similar conventional one. It also assesses the experimental and educational aspects which can lead to familiarization with techniques, systems, materials, etc. playing in other operations, both public and private
Architectural description
The building is the result to make compatible both architecture and sustainability, understood in its broadest sense. The social dwelling program is focussed on small size living units to rent, commercial shop on the ground floor and parking and storage rooms in the basement. Location is proposed on urban environment, small sized plot, between party walls having a central core access and services that enables to arrange the main building spaces on their periphery (on facades). It is totally composed by four 1 bedroom units on the first floor; 3 units on the second floor, two 2 bedroom and one, two bedrooms. The space saving and sustainability (saving water and energy) recomended a community laundry, located with other community facilities in low-cover plant, where are also located clotheslines. This arrangement allows great rationalization of facilities and, in the homes of two bedrooms, natural cross ventilation and double orientation of the main space.
If you had to do it again?
I would add more inertia and improve indoor thermal transmittance holes façade.
