Nota Uiterlijk van Bouwwerken Schiedam 2025 – Building Appearance Regulations
The Nota Uiterlijk van Bouwwerken Schiedam 2025 is the official municipal policy document of the Gemeente Schiedam, Netherlands, governing the architectural appearance of buildings and structures. Effective from December 19, 2025, this document replaces the previous Welstandsnota Schiedam 2019. It functions as a practical assessment framework within the legal context of the Omgevingswet (Environment Act), aiming to simplify regulations while maintaining environmental quality. The policy provides a structured approach for municipal planners and developers to evaluate construction plans based on their impact on the streetscape.
The scope of the document includes specific criteria for various building activities, categorised into object-oriented and area-oriented requirements. It defines distinct assessment levels through a Niveaukaart (Level Map), identifying zones such as Vrij (Free), Bijzonder (Special), and areas governed by Ontwikkelingskaders (Development Frameworks). The document covers structural elements including Aanbouwen (Additions), Dakkapellen (Dormers), Zonnepanelen (Solar Panels), and Reclame (Advertisements). Specific attention is given to the Binnenstad (City Centre) and the historic districts of Kethel and Kerkbuurt, which are subject to more stringent heritage protections.
This document serves as a reference for determining whether a project is permit-free or requires a formal review. The following sections detail the specific thresholds, spatial requirements, and qualitative standards defined in the 2025 edition.
Assessment Levels and Policy Maps
The Niveaukaart determines the intensity of the aesthetic review for any given location in Schiedam. The city is divided into three primary levels:
- Vrij (behoudens uitzonderingen): Applies to most residential and industrial areas where only minimal checks for excesses are performed. Exceptions include projects involving 5 or more ground-bound homes, apartments, or public buildings like schools.
- Bijzonder: High-level assessment required for the Binnenstad and Kethel/Kerkbuurt due to their status as protected city and village-scapes.
- Ontwikkelingskaders: Supplementary requirements from image quality plans apply to areas undergoing active redevelopment.
Criteria for Small Objects
Chapter 2 defines measurable criteria for common modifications to existing buildings. These criteria apply specifically within the Bijzonder level and for permit-required projects.
- Aanbouw (Additions): Must be subordinate to the main building. Erkers (bay windows) on the front facade are limited to a depth of 1.00 metre and a width of two-thirds of the facade.
- Dakkapel (Dormers): Maximum height is 1.50 metres. They must be placed at least 0.50 metres from the roof edges and the center of party walls. They should be 'standing' (taller than wide).
- Erfafscheiding (Fences): Front-facing fences must be part of a closed street wall, ideally partially masonry and partially transparent, using dark or restrained colours.
- Reclame (Advertisements): Billboards are only permitted at city entrances, public transport stops, and transit routes. Facade signs must not exceed 50% of the building width or 5.00 metres.
Solar Panels and Sustainability Installations
The regulation distinguishes between visible and non-visible placements, particularly in protected heritage zones. Visibility is assessed from public space at a height of 1.80 metres.
- Visible (Nadrukkelijk zichtbaar): Panels visible within 50 metres of public space. In historic locations like Lange Haven or Grote Markt, these are generally prohibited on front roof planes.
- Placement on Sloped Roofs: Panels must be arranged in a continuous rectangular block, maintaining a minimum distance of 50 cm from gutters and roof edges.
- Integrated PV: Replacing traditional tiles with integrated PV cells is generally not permitted on monuments or in protected views.
The Excessenregeling (Rules for Excessive Impact)
The Excessenregeling allows the municipality to intervene when a building's appearance is evidently and seriously detrimental to its surroundings, even for permit-free structures.
- Visual Closure: Fencing or boarding up a building in a way that blocks sightlines or isolates the structure from the street.
- Material Misuse: Use of materials considered poor or unsuitable for the specific architectural context.
- Contrast: Use of high-contrast or neon colours that disrupt the historical character of the Binnenstad.
The criteria for an 'exces' must be evident to non-experts.
Frequently Asked Questions
What is the maximum depth for a bay window (erker) in Schiedam?
According to the object criteria, an erker on the front facade may have a maximum depth of 1.00 metre.
Are solar panels allowed on the front of a house in the Schiedam city centre?
In historically valuable locations like the Binnenstad, visible solar panels are generally not permitted on front roof planes or facades.
What is the minimum distance for a dormer from the roof edge?
A dakkapel must maintain a minimum distance of 0.50 metres from the top and sides of the roof plane.
When does the 'Vrij' assessment level apply to residential projects?
The Vrij level applies to most residential areas, except for projects of 5 or more ground-bound houses or apartment buildings, which undergo a full assessment.
What counts as a 'standing' dormer?
The document specifies that dakkapellen should be 'staand', meaning they are taller than they are wide.
How is the 'front side' of a building defined for building regulations?
The Voorkant refers to the parts of the building and yard that are clearly visible from public space.
Can I paint a brick facade in the historic centre?
