About this service

Home extensions

An extension is the quickest way to enlarge your home without moving. Yet there is more to it than a few walls and a roof. The foundation must be right, the rear facade is opened up with a steel beam, and underfloor heating, electrics and finishing must connect seamlessly to the existing house.

BEMUTO handles the entire process: we draw the extension, check whether a permit is required, have the structural calculation made and build everything ourselves. Whether you choose traditional brickwork, timber frame construction or a sleek aluminium extension with lots of glass: you know in advance what it costs and when it will be finished.

From drawing to keys

We draw, apply for the permit and build ourselves. You don't need a separate architect, structural engineer and contractor.

Stay in your home

We work from the outside as much as possible and only open up the facade once the extension is wind- and watertight.

Frequently asked questions

Questions about home extensions

Can't find your question? We're happy to help.

Do I need a permit for a home extension?

Not always. At the rear of a house you can often extend up to 4 metres deep without a permit, provided a number of conditions are met. The local zoning plan and the situation on site determine what is allowed. We check this in advance and take care of the application if one is needed.

What does a home extension cost?

That depends on the dimensions, the foundation, the type of frames and the level of finish. An extension usually starts from around €30,000. After a visit on site you receive a tailor-made quote, so you're not left with a vague estimate.

How long does it take to build an extension?

The construction itself usually takes a few weeks, depending on the size and the foundation. Including design, any permit and the delivery time of frames, the total lead time is a few months. You receive a concrete schedule in advance.

What's the difference between an 'aanbouw' and an 'uitbouw'?

In Dutch, an 'uitbouw' is open to the existing room, such as a larger kitchen or living room, while an 'aanbouw' is a separate room built against the house, such as an extra bedroom or study. In practice both terms are used interchangeably. We build both.

Should I choose an aluminium or a timber extension?

An aluminium extension is sleek, low-maintenance and suitable for large glass surfaces. Timber frame construction and traditional brickwork often blend in better with a classic home. We discuss the pros and cons for your situation and budget.
