Aesthetics review: common mistakes
The aesthetics committee rejects more plans than you might expect. Not because the design is poor, but because common mistakes in the preparation or the drawings steer the committee in the wrong direction. A rejection can easily cost you four to eight extra weeks of lead time and additional drawing costs. This article explains the seven most common pitfalls and shows how to avoid them. Tekenpunt guides building plans in dozens of municipalities and sees the same mistakes recurring time and again. Understanding and addressing those patterns significantly increases the chance of a positive recommendation in the first round.
The seven most common mistakes in the aesthetics review are: materials or colours that clash with the surroundings, wrong proportions or placement, a window layout that conflicts with the existing facade, ignoring the fast-track criteria, incomplete facade drawings, uPVC where the code demands traditional materials and overlooking a protected townscape or listed status. A rejection quickly costs four to eight extra weeks. Reading the local policy rules beforehand and submitting complete drawings prevents most refusals.
Error 1: materials or colours that do not fit the surroundings
This is the most common reason for rejection. The environmental quality advisory committee assesses whether your structure fits in with the neighbourhood. Choosing a plastic facade in a street of red brick, or a striking colour that does not appear anywhere else in the row, gives the committee a direct reason to say no.
**What goes wrong.** Clients choose materials based on price, ease of maintenance or personal preference, without checking what the aesthetic review policy or the municipality's aesthetic review document prescribes. PVC window frames are a classic example: in neighbourhoods where the policy requires traditional materials such as wood or steel, they are systematically rejected. The same applies to plywood concrete, composite panels or coated aluminium profiles in locations where these deviate from the neighbourhood character.
**How to prevent it.** Before the design, read the applicable policy rules for your address and neighbourhood. Check which materials and colour tones dominate in the immediate surroundings. Align with these, or justify a deliberate deviation clearly in writing. Tekenpunt adds a materials schedule to every application with precise descriptions of colour (RAL or NCS codes), surface texture and material choice. This shows the committee that you have taken the surrounding context seriously.
Error 2: incorrect proportions or placement of the intervention
A dormer window that is too wide, an extension that protrudes too high or a roof extension that affects the roof shape of the home: proportions are just as important to the committee as the choice of materials.
**What goes wrong.** With dormer windows, the width relative to the roof surface is a commonly made mistake. Many municipalities use the quick-test criteria from the Buildings and Living Environment Decree (Bbl) as a minimum guideline, but the aesthetic review policy rules may impose stricter requirements. A dormer that covers the entire roof surface or starts too close to the ridge or the sides of the roof deviates from the common appearance and is quickly sent back. The placement height on the roof also plays a role: positioned too high or too low disrupts the composition of the facade.
The same applies to extensions that disrupt the building line or street profile, or to roof raises that change the silhouette of a terraced house to such an extent that the ensemble falls apart.
**How to prevent it.** Check the proportions of your design against the quick-test criteria and the area-specific rules. For dormer windows: ensure sufficient distance to the ridge, gutter and sides, and keep the width within the common dimension for your street type. Tekenpunt always draws an elevation to scale with the existing situation alongside, so the committee can see at a glance that the proportions are correct.
Error 3: frame layout that does not match the existing facade
Windows and doors determine the rhythm and appearance of a facade. A window frame layout that deviates from the rest of the property or the street immediately draws the attention of the committee.
**What goes wrong.** When replacing window frames, enlarging a window or breaking through a facade, clients sometimes choose a layout that is functionally logical (a larger light opening, a different width-to-height ratio) but visually clashes with the existing structure. A portrait window being replaced by a landscape one in a facade with exclusively portrait windows is a typical example. Or a symmetrical facade layout becoming asymmetrical through an additional window opening.
In protected townscapes or village scenes this is extra sensitive: the historic articulation of the facade is established and may not simply be altered.
**How to prevent it.** Analyse the existing facade layout before drawing a change. Preserve the existing rhythm of portrait versus landscape windows, the dimensions of the reveals and the height of the parapets. If a deviation is functionally necessary, substantiate this in writing. Tekenpunt draws the existing and new situation side by side at the same scale, so the committee can immediately see that the articulation is maintained or that there is a valid reason for a change.
Error 4: not taking the quick-assessment criteria into account
Many permit-required structures such as dormers, extensions, and outbuildings are assessed against the quick-assessment criteria. Anyone who does not know or ignores those criteria will get stuck early in the process.
**What goes wrong.** The quick-assessment criteria have been established to speed up and make the aesthetic review more predictable for common types of buildings. If your plan meets those criteria, the chance of a positive recommendation is high. But the criteria are specific: dimensions, placement, material, and colour are sometimes fixed down to the centimetre. Anyone who draws a dormer window that just falls outside the quick-assessment criteria, without this being intentional and motivated, gives the committee reason to doubt.
Some municipalities also have additional fixed examples or area-specific criteria that go further than the national fast-track criteria. Anyone who only knows the national rules and misses the local additions will still produce a plan that comes back.
**How to prevent it.** Always check which quick-test criteria apply to your type of intervention and which additional local criteria the municipality applies. Tekenpunt does this as standard for every application: we place the local policy document alongside the national criteria and assess the design against both.
Mistake 5: incomplete or unclear facade drawings
The committee can only assess what it sees. Incomplete drawings, missing material descriptions, or an unclear relationship to the surroundings lead directly to a deferral or rejection.
**What goes wrong.** An elevation drawing without dimensions, without stating the colour or material of the new elements, or without a scale indicator gives the committee too little to go on. The same applies to an application without a site sketch: the committee wants to see how the building relates to neighbouring properties and the building line. For larger interventions the committee also expects a street-level view, so it is clear what the plan looks like in the context of the surroundings.
Another common mistake is not providing the existing situation alongside the new situation. Without that comparison it is difficult for the committee to assess what exactly is changing.
**How to prevent it.** Always submit complete facade drawings: existing and new at the same scale, with dimensions, material descriptions and colour codes. Add a site plan showing the position relative to the surroundings. For larger interventions, a perspective or street elevation helps give the committee a clear picture. Tekenpunt delivers as standard a complete drawing package that meets what the committee expects: existing, new, facades, site plan and a materials schedule.
Error 6: plastic or non-standard materials where the policy document requires something different
This is a specific elaboration of mistake 1, but deserves its own paragraph because plastic is so often used incorrectly. In a large part of Dutch residential districts, the aesthetic policy document or policy rule prescribes that facade finishes, window frames and gutters are executed in traditional materials.
**What goes wrong.** Plastic window frames are cheaper to maintain and popular with clients. But in districts with a historic character, in protected townscapes and village scenes or at properties where the policy document explicitly requires wood or steel, plastic window frames are systematically rejected. The same applies to plastic facade cladding, cheap composite panels or spray-painted aluminium profiles that deviate from the surroundings in texture and appearance.
Commonly used panels and ceramic facade cladding can also cause problems if the surroundings consist entirely of brickwork. The committee looks not only at the colour, but also at the texture and the way light falls on the surface.
**How to prevent it.** Before choosing materials, always check the policy document or the policy rules of the municipality. If you deliberately choose a modern material, explain why it fits the surroundings and how the detailing ensures a quality appearance. When in doubt, Tekenpunt always advises seeking pre-consultation with the municipality or the committee first, especially if you want to use an unconventional material.
Mistake 7: ignoring a protected scene or monument
In protected townscapes and village scenes and for monuments, additional requirements apply on top of the regular aesthetic review. Those who do not know or ignore these will get stuck.
**What goes wrong.** Clients sometimes do not know that their property is located in a protected townscape, or they underestimate what that means for their options. A small facade change that quickly passes the review in an ordinary residential area may be rejected in a protected townscape because it affects the historic facade structure. Think of removing original ornaments, replacing glazing bars in windows with plain glazing, or placing a dormer on a side elevation that is visible from public space.
For national monuments the environmental quality advisory committee is legally required to advise. A negative recommendation carries significant weight in the permit decision. Those who do not know this in time underestimate the lead time and the risk of rejection.
**How to prevent it.** Always check before the first sketches whether your address is in a protected townscape or village scene or on the list of national or municipal monuments. You do this via the Omgevingsloket or the municipal environment plan viewer. In a protected scene a pre-consultation/concept request with the committee is almost always advisable: you find out early what adjustments the committee expects and you avoid surprises at the formal application stage.
Tekenpunt has experience with drawings for monument properties and protected conservation areas. We know the stricter requirements and align the design with them from the outset.
How Tekenpunt ensures your plan passes first time
Approximately 90% of the applications Tekenpunt handles pass the aesthetic review in the first round. That is no coincidence. It is the result of a consistent working method that structurally rules out the most common mistakes.
**Local rules first.** For every project we look up the applicable aesthetic review policy rules for your specific address: the municipal aesthetic review policy document or the spatial quality policy rules that serve as a guide under the temporary environment plan. Only once we know those rules do we start drawing.
**Correct facade drawings.** We always deliver existing and new side by side, at the same scale, with dimensions and material description. The committee gets everything it needs to form a well-substantiated judgement. No missing dimensions, no vague material description, no missing site drawing.
**Material schedule with every application.** Every application includes an overview of the materials and colours used, including colour codes where relevant. This makes it immediately clear to the committee that the choices align with the surroundings or that there is a good reason for a deliberate deviation.
**Advice on pre-consultation.** Are we unsure whether a plan will pass the review without difficulty? Then we always recommend submitting a concept request first. You find out early whether the direction is correct and avoid surprises after weeks of lead time.
A construction drawing via Tekenpunt starts from **€595**. If you want certainty about the aesthetic review, you can add aesthetic review guidance as an add-on. More about rates and what is included in the standard package, read on the [rates](/tarieven/) page.
Frequently asked questions
Q01Why is a plan rejected at the aesthetic review?
The most common reasons are: materials or colours that do not match the surroundings, proportions that deviate from the street scene, window frame layouts that disrupt the existing facade structure, plastic in places where the guidelines require traditional materials, or incomplete facade drawings. In protected scenes and with listed buildings, the historic facade structure and heritage values also play a major role.
Q02What are quick-assessment criteria and why are they important?
Quick-assessment criteria are pre-defined dimensions, placement rules, and material requirements for common types of buildings such as dormer windows and extensions. If your plan meets those criteria, the chance of a positive aesthetic review recommendation is high. Anyone who does not know the criteria or draws just outside the boundaries without motivation risks a deferral or rejection. Many municipalities also have additional local criteria that go beyond the national quick-assessment criteria.
Q03May I install plastic window frames if the neighbourhood consists entirely of brick houses?
That depends on the aesthetic review policy rules of your municipality. In neighbourhoods with a historic character, in protected townscapes or village scenes, or with properties where the document requires traditional materials, PVC window frames are systematically rejected. Always check the applicable policy rules for your address before finalising the material choice.
Q04How wide may a dormer window be for the aesthetic review?
The quick-assessment criteria set requirements for the width relative to the roof surface, the distance to the ridge and sides, and the installation height. But the municipality's aesthetic review policy rules may impose stricter or additional requirements. There is no universal answer: it depends on your municipality, the neighbourhood, and the type of property. Always have the dimensions checked against the local rules before you produce the final drawing.
Q05What is the difference between a regular aesthetic review and an assessment in a protected townscape?
In a protected townscape or village scene additional requirements apply on top of the regular aesthetic review. The historic facade structure, original materials and urban cohesion carry more weight. Even minor interventions such as replacing window frames or adding a dormer window can be refused if they affect the historic character. A pre-consultation/concept request with the committee is in such cases almost always advisable.
Q06How do I know if my property is in a protected townscape or monument zone?
Check the Omgevingsloket (omgevingsloket.nl) or the municipal environment plan viewer. For national listed buildings you can also consult the National Listed Buildings Register via the Cultural Heritage Agency of the Netherlands (RCE). Tekenpunt checks this as standard for every project.
Q07What must be included as a minimum in facade drawings for the aesthetic review?
As a minimum: existing and new situation side by side at the same scale, dimensions, material description with colour codes, and a site drawing showing the placement relative to the surroundings. For larger interventions the committee also expects a street elevation or perspective. If any of these components is missing, the committee will put the application on hold.
Q08How does Tekenpunt help to prevent rejection at the aesthetic review?
Tekenpunt always starts by reading the applicable municipal aesthetic review policy rules for your address, checks the design against them and delivers correct elevation drawings with existing and new side by side, dimensions and a materials schedule. When in doubt we advise submitting a concept application for pre-consultation. Approximately 90% of the applications guided by Tekenpunt passes the aesthetic review in the first round.
