The house is located in a peripheral neighbourhood characterised by a landscape of courtyards, empty plots and exposed partitions. The plot is 13.50 metres long, which is double the usual in the area and allows the construction of two barns. The project chooses to move the usual programme of a house to the first floor, maintaining the relationship between the bedrooms and the outside space. One of the gables is moved to the interior of the plot, creating new patios on the side of the façade. The cover is formed by two copper bands that undulate from façade to façade until they form the enclosure, favouring the use of the attic as a continuous space. The result is a home full of interstices and corners, where each space has at least two ways to get there and its own area of expansion. The house shares the interior garden with two other houses, and the south façade faces the house on the other side of the street, six metres away.

We find ourselves in a neighbourhood on the outskirts of Terrassa, on the other side of the stream, where most of the houses are self-built (as partly this one), of various types and sizes, dotted with plots and patios, caravans in storage, warehouses... where a discontinuous landscape is offered in which partition walls are predominant.

Four main decisions are made:
- 1 Move the ground floor of a conventional programme to the level of the first floor, allowing rooms to participate in the exterior spaces.
- 2 Offset the two volumes, generating closed patios that control the views from and towards the house.
- 3 Solve the requirement of the sloping roof and the attic by extending two copper locks that curve and wave to collect the space under the roof, hanging from the back until closing the north façade of the bedroom volume.
- 4 Allocate the main part of the low budget to the structure and the roof, saving on the rest: façades of Portland stucco or Betonite and finishes executed by the owner over a long period.

With the deformation and fragmentation of the envelope, interstices, waste and corners appear inside: the "anti-loft". Each space has at least two ways to reach it and is related to its own area of expansion: the couple's bedroom with the study (towards the living room), the playroom with the south patio, the children's bedroom with the loft, the kitchen with the dining area and the patio or the living room with the patios to the north and south.

Plot of land with a width of 13.5 metres, double what is usual in Terrassa, where to build a ground floor, first floor and under deck, for a young couple with two children. It shares a garden in the interior of the block with two family houses and faces its south façade to a local "cavity wall" house, on the other side of a six-metre street. In this context, the house creates its own external spaces and adopts the grey and reddish colors of its surroundings and of the mother and sister's own houses: unpainted finished façades, roofs of tiles or tiles and unclad partitions.

Four main decisions are made:

1- Move the ground floor of a conventional program to the level of the first floor, allowing rooms to participate in the outdoor spaces.
2- Offset the two volumes, creating closed patios that control the views from and towards the house.
3- Solve the requirement of the sloping roof and the attic by extending two copper sheets that curve and undulate to collect the space under the roof, hanging from the back until closing the north façade of the bedroom volume.
4- Allocate the main part of the scarce budget to the structure and the roof, saving the rest: façades of Portland stucco or Betonite and finishes executed by the owner himself over a long period of time.

The enclosure between the room and the south courtyard is formed by means of fixed glass and sliding opaque panels. What moves are, therefore, the walls. A second band of guides makes it possible to hang wicker and tarpaulin curtains in the summer, and in the future, more solid shutters. The metal structure and DM board are visible inside, the exterior carpentry is of copperised wood and for some time the patios and garden will be covered with pebbles. The house, once closed by the contractor and his guilds, is completed little by little in installations, painting and other finishes by its inhabitants, already installed in it.
