Casa Peña is the product of a formal and conceptual research based on two main ideas: firstly the need of a pavilion-like structure which would allow for the surrounding views of the mountains and valleys, and secondly the need to demonstrate by means of an innovative construction technique, we can reforest our path to the sustainable way of building of tomorrow.
This structural concept, takes into account that over the centuries, the way we build our homes and cities has resulted in the fact that we use 3 tons of concrete per capita per year, which accounts between 5-8% of global overall GHG emissions, meaning that its urgent to find an implement an alternative solution which not only reduce GHG emissions, but sequester them. Laminated timber can become a key ally since it is literally made of carbon, it is sequestered in the wood, and will be stored for the lifetime of the building. Sustainable sourcing of wood is imperative, for it must come from a certifiable and responsible supplier, and never from old growth forests.
With this in mind, the roofs and floors are wooden structural CLT (Cross Laminated Timber) elements, innovating in its use in México, and the 50 m3 of CLT result in 44 MT of sequestered CO2, and 17 MT of reduced GHG emissions.
140 mm deep, the CLT panels support a shallow substrate for shrubs, bushes and succulent plants, all native to the local environment, to restore the footprint of the construction, and with a root barrier waterproofing out of HDPE, to prevent any damages from humidity.
The inverted Glulam beams support the CLT panels, and provide a clean wooden surface underneath, to showcase the wooden structure. Columns are also built out of mass-timber Glulam, and support the whole roof, and distribute the loads to masonry retaining walls.
Energy -wise the house will be powered entirely with solar panels, as well as water heating and radiant floors with thermal-solar heating. The water supply is sourced from rainwater harvesting, which is potabilized and used in the house, after which it is sent to a treatment unit and wetland, allowing reuse of water for irrigation and toilets, aiming for total water efficiency.
The architectural concept was inspired by the work of the Mexican painter Gerardo Murillo, “Dr. Atl”, a praising symphony of volcanoes and land, a pedestal of man overlooking the hazy exchange between Popocatépetl and Iztaccihuatl, on top of a stony outcrop above Tenango del Aire.
The volumetry was based on the continuation of the rocky landscape, appearing on the outside as a hard, sculpted element emerging from a ridge at the cusp of a hill. On the inside, clean and exposed stone, contrasting with the wooden surfaces, create a cozy atmosphere. Lightly posed above the outcrop, the canopy recreates the landscape, as it crowns the carved podium.
“Among your slumbering cusp in the silent night, man as on a pedestal…” Dr. Atl
