More light in the living room, a classic streetscape and immediate added value for your home. A bay window is a statement extension at the front facade with glazing all around. We produce the permit-ready drawing from €795 and guide the aesthetic review in full.
A bay window is an extension on the front facade (sometimes side facade) of the living room with window frames on at least three sides, providing more natural light and a sense of space. Tekenpunt delivers the permit-ready drawing from €795 within 4 weeks (express 1-2 weeks). If the bay window requires a permit, allow 8 weeks for the municipal decision.
It dramatically enlarges the space visually and draws in daylight from multiple sides. These are the elements we draw and calculate.
The roof of the bay window connects to the facade. A flat cover in EPDM or zinc is most common; a small pitched or lean-to roof suits older architectural styles.
The closed panel at the bottom, from breast height to the floor. Solid masonry, rendered concrete or a timber-frame variant, depending on the structure and aesthetic requirements.
The three sides (front and two flanks) are fully or partially glazed. The frame layout defines the character: slender bars for a classic bay window, bare profiles for a modern one.
An insulated floor slab on a new foundation or cantilever construction. The floor connects to the existing living room floor at the same level.
Even a small bay window requires its own foundation, typically a concrete strip or piles. This partly determines the lead time and construction costs.
The connection to the existing facade. The lintel carries the brickwork above the bay window opening; the damp-proof course and pointing determine long-term durability.

A bay window on the front facade is visible from the public road and therefore almost always requires a building permit with aesthetic review. We handle the drawing and the application; 90% passes first time. Request a no-obligation quote for your exact situation.

From a classic front-facade bay window to a spacious corner variant or a bay window spanning two storeys. We advise on what suits the architectural style and what the municipality permits.
Rectangular bay window with three frames, centred in the living room facade. Fits perfectly with 1920s to 1950s homes. Always subject to a permit with aesthetic review.
An angular bay window that glazes the living room on two sides. Provides maximum daylight and views. Requires precise structural detailing for the corner solution.
A continuous bay window from ground floor to upper floor. Maximum impact on the streetscape and the value of the property. Requires more structural work and extensive drawing.
A bay window enlarges the front living room without sacrificing the garden. Here is how it compares to a rear extension and a facade alteration.
A bay window on the front facade almost always requires a permit. How strict the aesthetic review is varies by municipality, neighbourhood and architectural style. An overview of typical situations.
Example project · front facade living room · aesthetic review · added property value
Challenge: A family in Den Haag lived in a 1930s mid-terrace house with a small, dark front living room. The windows were narrow with barely any daylight. They wanted more space and light but were concerned about the aesthetic review in their neighbourhood.
Our approach: We designed a classic bay window 3 m wide and 1.2 m deep, in keeping with the architectural style of the neighbourhood: a brick parapet, slender window frames with glazing bars and a zinc-covered flat roof. The design aligned with Den Haag's aesthetic policy for pre-war districts. We handled the permit application including the design quality plan.
Result: Permit granted in 6 weeks. A brighter living room with 5 m² of extra floor space, a noticeably improved appearance and a demonstrably higher assessed value. The complete drawing was ready in 4 weeks.
A bay window is an investment in living comfort and property value. What you still need to know.
A bay window on the front facade is always assessed by the aesthetics committee. We know the aesthetic policies of municipalities across the Netherlands and design specifically for first-time approval.
SOURCE · ENVIRONMENT ACT 2026 / BBLA well-designed bay window demonstrably increases the appraised value of a property. Estate agents cite a well-executed bay window as one of the most cost-effective facade improvements.
ADVICE · Consult your appraiserA bay window can be co-financed in a renovation mortgage (up to 106% of the value after renovation). Your adviser calculates whether the added value covers the additional financing costs.
BRON · NHG.NL 2026Almost always. A bay window is usually located on the front facade and is visible from the public road; this makes it subject to a permit with an aesthetic review. A small subordinate bay window on the side or rear facade can be permit-free under strict conditions of the BBL (Buildings and Living Environment Decree): maximum 1.5 m deep, maximum 2.5 m wide and no higher than 1 storey. We check your situation free of charge.
A bay window drawing starts from €795. The construction itself (by a contractor) typically ranges between €15.000 and €35.000, depending on dimensions, foundation, window frames and finish. The drawing determines the quality of the permit application and the execution.
There are no fixed national maximum dimensions for a bay window requiring a permit; the municipality assesses against the zoning plan and aesthetic policy. A small bay window in the front garden area may be permit-free if it is at most 1.5 m deep, less than 2.5 m wide and no higher than one storey. We assess feasibility for your specific address.
A bay window is a relatively small projection on the front facade of the living room, with glazed walls or window frames all around. An extension is generally larger, at the rear, and more enclosed. A bay window increases the sense of space and light; an extension significantly increases the actual floor area. We advise which solution best suits your requirements.
We deliver the drawing within 4 weeks (express 1-2 weeks). For a bay window requiring a building permit, allow an 8-week municipal decision period after submission. Aesthetic review guidance is included in our standard service. For a listed building or protected townscape, it can take 10-14 weeks.
