Project Basel BS

Gut renovation with extension in 10 months

We completely renovated a detached house in Basel and added a three-storey extension. It adds around 60 m² of floor space: a larger living room, a study, two bathrooms and a plant room.

From the building permit and the new heat pump to the country-style kitchen, everything came from one source.

Frequently asked questions

Questions about renovating in Basel

Christian Vogt
Reviewed by Christian VogtArchitect BA ZFH · Updated October 2026
What does a bathroom renovation in Basel cost?

A medium-sized bathroom of 6 to 9 m² as a complete renovation costs roughly CHF 25'000 to 40'000, a partial renovation with new sanitaryware, fittings and furniture roughly CHF 10'000 to 16'000. You will find out the exact costs after the site visit. More under bathroom renovation.

Who issues building permits in Basel?

In Basel-Stadt, the Building and Hospitality Inspectorate (BGI) is responsible. In Basel-Landschaft, the cantonal building inspectorate processes the building applications of all municipalities except Reinach, which has its own building inspectorate. We clarify in advance which procedure your renovation needs and take on the building permit application.

Do I need a permit in Basel-Stadt to refurbish a rented flat?

Possibly. Housing protection rules apply in Basel-Stadt. Refurbishments, renovations and conversions of rented flats may fall under them and require an additional permit. We clarify this for your property before planning starts.

How long does a renovation in Basel take?

Depending on the scope, between a few weeks and several months. In Pratteln we renovated two bathrooms in three weeks, and a flat in Basel before moving in in six weeks. If a building permit is needed, the procedure is added.

Do you also work in Baselland?

Yes. From our location in Basel we look after projects in Basel-Stadt and Basel-Landschaft, for example in Pratteln, Füllinsdorf and Bubendorf.

What does renovation from a single source mean?

You have one contact person for everything: advice on site, planning by our architects, building permit application, comparable quotes from vetted tradespeople, construction management through to handover and defect management. You can see the status online at any time on our platform.
