Je volgt je hele aanvraag live in je eigen online dossier, van offerte tot oplevering.
An extension is a ground-floor addition to the existing home, usually at the rear for a larger living room or kitchen. An extension can also wrap around the house (such as a conservatory). These are the elements we draw.
A concrete foundation beam on piles or a slab foundation, depending on the soil conditions. The base on which the extension rests.
Almost always a flat roof with bitumen or EPDM and a neat roof trim. A flat covering is required for permit-free projects.
Side walls in brickwork to match the house, or in lightweight timber-frame construction. Including insulation and cavity.
The connection to the existing rear facade: waterproofing, the expansion joint detail and the wall opening are critical here.
An insulated ground floor, often with underfloor heating, that seamlessly connects to the existing floor level.
Often a large glazed facade or folding wall towards the garden. Determines how much light enters and the connection with outside.

From a sleek permit-free extension to a full wraparound extension. We advise on what is permitted and what looks good.
Flat-roofed extension at the rear facade, clean and straight-lined. Up to approximately 4 metres deep, usually permit-free and the quickest to arrange.
An extension with a sloping lean-to roof and large areas of glass or a rooflight. More elegant and lighter, but often requires a building permit because of the roof form.
A spacious extension or glass conservatory, sometimes wraparound or full-width. Maximum light and space; almost always a building permit and structural calculation required.
An extension is the most direct way to gain living space on the ground floor. Here is how it relates to an attached conservatory and a roof extension or dormer.
The permit-free rules are the same nationwide, but for an extension that requires a permit the aesthetic review differs per municipality. A few typical situations.
Example project · rear facade · permit-free · open living kitchen
Challenge: A family in Haarlem had a small kitchen that was separate from the living room. They wanted a spacious open kitchen-diner at the rear with plenty of light towards the garden, but did not know whether a permit was required or how far they could extend.
Our approach: We checked the design against the permit-free rules: rear facade, flat roof, within the rear garden area and up to 4 metres deep. No permit required. We delivered a complete, dimensioned drawing with foundation, floor detail, a large glazed facade and the connection to the existing wall, plus a light structural calculation for the span.
Result: 18 m² extra living space, a light open kitchen-diner and no permit process. Drawing in 0-3 weeks, the contractor could start straight away.
An extension is a valuable intervention that increases your living area. What you still need to know.
Rear facade, not a listed building, flat roof, within the rear plot area and up to approximately 4 metres deep: usually permit-free. We verify this in the drawing.
SOURCE · BBL / ENVIRONMENT ACT 2026For an extension, insulate the new floor, walls and flat roof well, often with underfloor heating. More comfortable and beneficial for your energy label.
ADVICE · Rc ≥ 6.3 new sectionAn extension increases the living area and often raises the property value. It can be co-financed through a renovation mortgage (up to 106% of the post-renovation value).
BRON · NHG.NL 2026Often yes, up to a certain depth. An extension at the rear facade within the rear plot area is usually permit-free if it has a flat roof and remains approximately up to 4 metres deep (depending on plot size and the conditions of the BBL and the Environment Act). At the front or side, or for a listed building, a building permit is required. We check it free of charge.
Een vergunbare uitbouw-tekening kost vanaf €645, afhankelijk van de situatie. De bouw zelf (door een aannemer, niet bij ons) ligt indicatief tussen €1.500 en €2.500 per m², afhankelijk van afwerking, pui en fundering.
Without a permit, a rear extension is usually possible up to approximately 4 metres deep, provided it is within the rear plot area and has a flat roof. Beyond that depth or for a larger plot, more may be possible with a permit. We assess your exact situation.
Yes. An extension rests on its own foundation, often a concrete foundation beam on piles or a slab foundation, depending on the ground conditions. We include this in the construction drawing and, for larger spans, in the structural calculation.
We deliver the drawing within 0-3 weeks (express 0-2 weeks). If a permit is required, allow 8 weeks for the municipal decision period. The construction itself often takes a few weeks depending on the scale.
Yes. We draw extensions across the Netherlands. We handle the drawings remotely and submit any required building permit to your municipality. We know or verify the aesthetic policy for every municipality.

We zagen op tegen de papierwinkel voor onze uitbouw in Den Haag, maar Tekenpunt heeft ons alles uit handen genomen. De vergunning was met 0-3 weken geregeld, echt ongekend snel. Ook de communicatie via WhatsApp verliep soepel en persoonlijk.
Extension / additionHeel blij met het meedenken. De constructieberekening voor de uitbouw was erg compleet. Geen gezeur met de gemeente Zaanstad.
Extension / additionFantastische ervaring. We hadden met spoed een constructieberekening nodig voor een uitbouw. Binnen no-time hadden we de documenten in huis, en de gemeente Eindhoven ging zonder problemen akkoord. De prijs was vooraf heel helder, geen verrassingen achteraf.
