Inner city facade


Participants: Arnau Llabres Forner and Enric Bulto. Given the dense and complex urban context, the construction is based on a rational and optimised system. Structure consists of columns and beams parallel to the facade, where the floor structure is laid on. Inside that grid, the “facade modules” are inserted. Those modules are a complex assembly consisting of the different layers to play with, which ultimately give the user the choice to adjust light, air and sight from the outside. The final outcome aims to provide an optimal tool for the residents, so it can serve and be inhabited in as many ways as possible.

Key benefit

It responds to multiple scales and topics: from the ground to the top floor and from sustainability to urban scale.

Material list

Kerto LVL:
- Columns, 8x kerto LVL panel 33x200mm
- Main beams, 8x ketro LVL panel 33x200mm
- Floor module beams, ketro LVL panel 33x200mm every 500mm
- Window module interior frame, ketro LVL panel 33x200mm

Ecological values

While being a sustainable building material, wood also brings up a versatility in construction that makes it ideal to be used in many ways. The renovation of the skin of the building, using more insulating and air tight components enhances drastically the energetic performance of the houses. The multiple layers and filters added to the facade, make it possible to be adaptable during the whole year and provide the house with the energetic flows required. It is also worth noting that the module/component off-site construction method, offers a better building environment, reducing the waste of time and material from a conventional work.

  • This Hybrid City competition entry is a renovation idea for any type of supporting structure. It focuses on the creation of a thermally high performing envelope to one part of the building. It creates semi outdoor living spaces similar to balconies and uses Kerto-LVL as the structural elements decoupled from the remaining structure.
