This Detached house is located on a plot of 628 m2, where the demolition of the existing building, built in 1970 was made, but keeping the pool of 34 m2, built in 2012. It is south facing with large windows in the facade to ensure natural light and solar gain. It has adjustable louver shutters and pergola on the south side, to prevent overheating in summer.
The house has a garage in the basement, an open-plan area with kitchen, dining and living room with access to the garden, and a toilet, a bedroom and a bathroom, all on the ground floor. On the first floor are four bedrooms and two bathrooms.
We used two different construction systems. The basement has been built with reinforced concrete walls with a system of permanent shuttering XPS insulation. Above it the ground floor and first floor, built with a wood frame, of Finnish red pine stand. The facades have air chamber and insulation between the wooden structure. The southern facade has a stone cladding of the area, while the rest are covered with lime mortar and painted with light colors.
The foundation is a suspended floor, and intermediate floors are unidirectional and are constructed by laminated fir beams. The cover is a water, built with the same type of intermediate slabs, and is finished with tile.
As for the facilities, the housing has an aero-thermal pump heat Rotex HSPU Compact for domestic hot water, and a mechanical ventilation double flow system with boiler enthalpic heat, which in turn serves to climatize the housing thanks to the battery post-treatment air installed in the system. The battery is fed from the heat pump. Finally there is a fireplace in the living room for the coldest winter days.

Owner approach of sustainability
The housing in Tossa de Mar has been designed and built according to the Spanish legislation, fulfilling the CTE and taking into particular consideration the DB-HE. Priority has been given to thermal comfort and to drastically reduce energy demands, thanks to thermal insulation, reduction of thermal bridges and ensuring the sealing, which means that cold spots and currents are minimized. As far as possible, they have chosen materials with a low environmental impact, such as the isolation of recycled cellulose or paints natural pigments, and have sought materials from those closest to the situation of housing areas.
Architectural description
The property consists of 143.70 m2 on two floors. the existing building to allow new construction was demolished, but the pool built in 2012. In terms of design, two different construction systems were combined. First, a structure of reinforced concrete was chosen for the basement walls and floor slab for floors in contact with the ground. On the other hand, a solid wood structure of Finnish red pine was chosen for the facades of ground floor and first floor, beams and slabs of fir wood for housing and intermediate floors.
