Renovating an 81 m² flat on Carrer Cartagena: a living area open to the balcony

Renovation of a flat in a 1972 building on Carrer Cartagena, Barcelona. Partitions are removed to enlarge the kitchen and join it to the living-dining room; kitchen, bathrooms, windows and services are renewed, leaving the home with two double bedrooms — one en suite — a balcony and a utility room.

The brief

A flat that had to adapt to new needs

The flat, in a 1972 residential building with load-bearing walls and one-way floor slabs, needed bringing up to date: a larger kitchen, better connection between the living spaces and new services.

The design partly changes the layout, removing partitions to join spaces, and renews the windows and doors, kitchen and bathroom fittings and the electrical, telecoms and ventilation services.

The living area

Kitchen, dining and living in one space

Partitions are removed to enlarge the kitchen and open it to the living room.

The kitchen grows and opens onto the living-dining room, which leads to the balcony. A low wall separates the work area without closing off the space, while light-wood units with a white worktop, under-cabinet lighting and the wooden floor give continuity to the whole living area.

The bathrooms

Two new bathrooms

Terrazzo, wall-hung fittings and black taps.

All bathroom fittings are renewed, with changes to the plumbing and drainage connections. The main bathroom pairs a terrazzo wall with the shower, a wall-hung vanity and black taps; the en suite bathroom follows the same style.

Bedrooms, balcony and utility room

Quiet bedrooms and a balcony onto the street

New windows, faithful to the originals.

The two double bedrooms, one en suite, are renewed with the same light wooden floor and warm-toned walls. The windows are replaced while keeping the layout and colour of the building’s originals. The balcony, overlooking a tree-lined street, and the utility room complete the home.

Frequently asked questions

Renovating a flat in Barcelona

It depends on the scope. If the layout and services change, usually a works notification with a technical design and, once finished, an updated habitability certificate. We handle the whole process.

Windows are part of the façade, so it is best to keep the building’s layout and colour, as here. We check the regulations and the residents’ association.

It depends on the scope. In this case, with a partial new layout, new kitchen and bathrooms, windows and services, the construction budget was about €25,400.
