Planning a home extension? More space, without the hassle
A bigger kitchen, a bright living room or an extra bedroom downstairs: BEMUTO builds your extension from drawing to handover. Throughout the Netherlands, with one dedicated point of contact.
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.
Who it's for
- Homeowners who want more living space without moving
- Anyone looking to enlarge the kitchen or living room with a rear extension
- Anyone who wants design, permit and construction from one party

“We hebben onze badkamer laten verbouwen door Bemuto en zijn super tevreden. Ze dachten goed mee over de indeling, de offerte en communicatie was helder en de planning werd netjes aangehouden. Ze werkten netjes en lieten elke dag alles opgeruimd achter. De afwerking is perfect, het voelt als een compleet nieuwe ruimte. Een echte aanrader”

“Tornike heeft mij goed geholpen in de rol als bouwbegeleider. Met zijn kennis en ervaring hebben we onze verbouwing goed voorbereid, offertes goed kunnen vergelijken en aannemers de juiste vragen gesteld waardoor we scherpere offertes kregen. Hij was in staat de vertaling te maken van onze wensen naar een juiste offerte bij de voor ons juiste aannemer.”

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 your wishes, the dimensions, the foundation, the type of frames and the level of finish. 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.
