Basement renovation in Sant Andreu.

What changes in a properly converted basement

In areas such as Sant Andreu and La Trinitat Vella basements usually sit beneath older houses or under the ground floor of apartment buildings, with stone or brick walls against the soil and salt marks low down. Access is nearly always a narrow stair, so we carry materials down by hand and take rubble out in sacks.

Finishes depend on use: a tiled floor and stable temperature for a wine cellar, rubber flooring for a gym, moisture-resistant board and an insulated floor for a living space. In areas such as La Sagrera, Navas and El Congrés i els Indians we check the headroom first, as it sometimes limits the insulation.

We take rubble out in sacks, protect the route through the house and leave the basement clean with the ventilation tested. We convert basements nearby too: Nou Barris, Horta-Guinardó and Sant Martí.
