An uitbouw (rear extension) makes an existing room bigger, usually the living room or kitchen at the back of the house. An aanbouw is a new room built onto the house, such as an extra bedroom, workspace or utility room. For the building work it makes little difference: both get a foundation, walls, a roof and window and door frames, and with an uitbouw the back wall is opened up.
People choose an extension to:
We do the building work and also the plumbing, the electrics, the heating and the finishing inside. So you do not have to coordinate separate contractors, and you have one fixed contact from start to finish.
The base of the extension: insulated formwork, reinforcement and poured concrete for the foundation and the floor. We match the foundation to the ground and the structure.
Where the back wall is opened up, a steel beam takes the weight of the wall above it. That gives you an open connection between the house and the extension.
Traditional masonry, with an inner wall of blocks and an outer wall of brick, or a timber frame with insulation and a brick façade. We discuss beforehand what suits your house best.
Timber joists with roof boarding, insulation and bitumen roofing, with a neat roof edge and drainage for the rainwater.
Sliding doors to the garden, French doors or extra windows in the side wall. We fit them watertight and finish them neatly into the brickwork.
Plastering, flooring, electrics and heating in the new room. Because we do this ourselves as well, the extension is finished as soon as the building work is done.
We build extensions from Almere within a radius of roughly 50 to 60 kilometres. For an extension we like to come and have a look first, so that the quote matches your situation.
In Almere you pay no call-out charge. Outside Almere we charge a single fixed amount of €42.35 incl. VAT (€35 excl. VAT), however far away you live within the service area.

A new kitchen in the extension? See kitchen installation for the pipes and connections. You can read about underfloor heating or an extra radiator under radiators and underfloor heating, and about extra circuits in the meter cupboard under electrics and consumer units.
Want to tackle the rest of the house at the same time? Have a look at full renovation. For a timber canopy or garden house we have a page of its own: canopies and garden houses.
Is your question not listed? Feel free to call or WhatsApp us, also outside office hours.
Often not. At the back of the house you may build without a permit under certain conditions, for example up to 4 metres deep. Whether that applies to your home depends on the size, the position and the rules of your municipality. Do the permit check on the Omgevingsloket, the government's permit portal, or ask us: we will look at it with you.
That depends on the size, the foundation, the choice of brickwork or timber frame, the roof and the doors. You always get a quote with a fixed price from us first, so you know where you stand beforehand. Feel free to send a photo and the measurements on WhatsApp for a first estimate.
Both give you a sturdy, well-insulated extension. A timber frame is lighter and quicker to put up; a brick extension is the traditional way. From the outside they can look the same, with a brick façade. We will advise you on what suits your house best.
That depends on the size and how it is built. The quote also includes the schedule, so you know when we start and when the extension will be finished.
Usually, yes. Most of the work happens outside. We plan it so that the back wall is open for as short a time as possible, and we keep the work area safe and tidy.
Yes. We also do the plastering, the floor, the electrics, the heating and, if you like, the kitchen in the new room. So you have one point of contact for the whole extension.
Send us a photo of the back of your house and the measurements you have in mind, on WhatsApp or through the quote form. We will get back to you quickly to make an appointment and give you a quote with a fixed price.
A leak or a blocked drain? Send a photo and I will take a look.
