A extended strip of glazing runs along the front of this cantilevered Spanish property by Alventosa Morell Arquitectes, providing the two siblings who inhabit it views of a mountain variety near Barcelona .
The two sisters commissioned Barcelona studio Alventosa Morell Arquitectes to style the timber residence named Casa LLP, which looks out over the Collserola mountains from its hillside plot.
The summit of the mountain range near Barcelona is marked by a communications tower made by the British architect Norman Foster.
Just two retaining walls have been built on the sloping site to help the light-weight wooden structure, which cantilevers more than the lower of the two concrete walls.
A bioclimatic examine of the site was carried out to inform the design and style of the residence, which utilizes all-natural heating and amazing-air systems.
The home is book-ened by a pair of decked patios. It also features a long balcony on its cantilevered facade and a ramped observation deck containing clerestory windows on the green roof.
As effectively as offering ventilation for the developing, these characteristics are all made to permit the residents to get in views of the verdant mountain assortment.
“This building has been developed following the request of two sisters for a bioclimatic home, exactly where they could live with each other and independently at the exact same time,” stated the architects.

“Right after the bioclimatic examine of this exact level we made a decision the approaches of the venture, in buy to maximise the environmental and thermal overall performance, and to adhere to the equivalent demands to develop a passive residence.”
The glazed southern facade and rooflights aid to capture heat and light from the sun in the course of winter months, whilst the green roof and wooden facade retain the warmth.
These contributed to the building’s low power consumption for heating, which is just 9 kilowatt-hrs per square metre – exceeding the power efficiency necessary to receive Passivhaus minimal-vitality certification.
A increasing quantity of buildings are being constructed to consume minor power and even produce much more electrical power than they use. Amongst them is a prefabricated timber house in Melbourne and a row of townhouses in Boston that enable residents to sell surplus vitality back to the grid.
“We increase the comfort of the creating by compaction, capture and sun protection, thermal resistance and cross ventilation,” explained the architects.
“The demand on heating has been beneath the limits of a Passivhaus (15 Kwh/m2a), and it has been solved with just a fire area for each person.”
White boxes wedged among the bare timber floorboards and exposed rafters define identical suites of rooms for the two sisters inside the property.
Every single of the the siblings has her own sitting room with a fireplace and access to the balcony, kitchen and bedroom.
“The framing walls organise the different spaces of the home with the concept that every female could have two rooms, a dining and a sitting area, a bathroom, a kitchen and a terrace to put into action the primary rooms,” explained the architects.
