Cal Gall
The house and farmhouses of Cal Gall, built in the 19th century, have been transformed by Taller SAU and reinvented with the aim of promoting the family's heritage.
Four spaces are organised around the courtyard: from bottom to top and from south to north. On the ground floor we find the day area, connected to the outdoor space while the upper floor serves as the nighttime area. To the south, the main rooms (living room and bedrooms) benefit from solar radiation, and to the north, the staircase and bathrooms act as a thermal cushion and bring together the facilities.
The wooden structure of the new floor slab and the new roof reinforce the stone walls and strengthen the ensemble of buildings. Traditional construction is combined with the new systems of plywood and dry construction.
Taking advantage of the high groundwater level, the whole complex is heated through a system of geothermal wells and underfloor heating, which guarantees the use of the thermal inertia of the stone walls and provides hot water in an almost natural way. Furthermore, the new roof, with 28 cm rock wool insulation, and the cross ventilation provided by opening new openings in the stone walls, allows the building to perform exceptionally well in both summer and winter with a minimum of external energy input. This is a clear commitment to low energy consumption.
