Precast concrete house in Barcelona
For this detached house in the Maresme we wanted a level of quality and control that, with conventional construction, is only achieved through very close site supervision. That is why we designed it with insulated precast concrete walls, made by the company Arumí. Here is how it went and what this system offers.
Why we chose an industrialised system
- Better cost control. The precast system has a fixed price. In conventional construction, if the project is not well defined and the works are not supervised, unforeseen costs and extras push the budget off course.
- Factory quality. The concrete is produced with controlled humidity and temperature, quality checks are more thorough and the panel dimensions more precise.
- Fast assembly. The façades and the floor and roof structures were assembled in 4 weeks.
- A bespoke house. Because the façades and structure are made to measure, the house does not depend on a catalogue, as many prefabricated or modular houses do.
Insulated precast concrete walls
With concrete panels insulated on the outside, the envelope was almost complete in under 3 weeks. The reinforced concrete panel, which carries the house, is protected by the insulation from rain and temperature changes, which are what wear structures down over the years. That is why it lasts much longer.
The design: sea views and winter sun
The plot has spectacular sea views. The design makes the most of them with a covered porch along the living room, which also lets the winter sun in to make the most of its warmth.
Finishes and building services
- Solid natural oak floors and porcelain stoneware in the bathrooms.
- Windows with 3+3/16/4+4 safety glazing with a low-emissivity cavity and 5-chamber thermally reinforced frames.
- Underfloor heating throughout.
- Double-flow ventilation that filters the air.
With a highly insulated envelope and well-sealed windows, it is a very energy-efficient house.
