Welstand op het water 2018 (Technical Revision 2024) – Amsterdam Floating Structure Regulations
The Welstand op het water 2018 (technical revision January 2024) is an official regulatory document issued by the Gemeente Amsterdam. It serves as the formal assessment framework for the spatial quality of objects on and along the water within the municipalities of Amsterdam and Weesp. This document is an integral part of the broader municipal welfare policy known as De Schoonheid van Amsterdam. It establishes guidelines for projects requiring a permit under the Omgevingswet (Environment Act) or meeting the conditions of a mooring permit.
The scope of this policy includes static floating objects intended to function in a fixed location. This covers Schepen (authentic or original ships), Vaartuigen (ship hulls with modified superstructures), Arken en waterwoningen (rectangular floating dwellings), Installaties (installations such as solar panels or satellite dishes), and Oevervoorzieningen (shore facilities like jetties and gangways). The document categorizes the city into nine distinct Ruimtelijke systemen (spatial systems), ranging from the historic Grachten and the Amstel river to industrial harbors and the rural landscape of Landelijk Noord.
This regulatory framework defines three assessment levels—Bijzonder (Strong), Gewoon (Normal), and Eenvoudig (Light)—which dictate the degree of scrutiny applied to a plan. It provides concrete criteria for design elements including ship proportions, material use, and heritage preservation, ensuring that floating structures contribute positively to the public domain and the historic city appearance.
Object Classification and Definitions
The document distinguishes between different types of floating objects based on their origin and physical characteristics. Each category is subject to specific architectural and aesthetic requirements.
- Schepen: Recognizable as original or authentic sailing vessels, typically featuring a curved hull (zeeg), streamlined form, and specific maritime elements like a voordek, stuurhut, and roer.
- Vaartuigen: Objects consisting of an original ship hull but featuring a non-original superstructure, often adapted for use as a residence.
- Arken en waterwoningen: Floating structures not originally built for navigation, usually featuring a rectangular hull and a superstructure designed primarily as a living or workspace.
- Oevervoorzieningen: Facilities directly related to the use of a boat, such as gangways, stairs, and jetties, located on the water's edge or against quay walls.
Spatial Systems and Assessment Levels
Amsterdam is divided into spatial systems to ensure that welfare criteria reflect the local context and character. Each system is assigned one of three Welstandsniveau's.
- Bijzonder (Strong): Applied to areas of high city importance like the Grachten, Amstel, and Landelijk Noord. Objects must actively contribute to the environment's quality.
- Gewoon (Normal): The standard level for most city areas, focusing on maintaining existing spatial quality and practical management.
- Eenvoudig (Light): Applied to areas where ambitions are limited, such as Vaarten and certain Industriehavens. The focus is on preventing significant negative contrasts.
General Welfare Criteria
All assessments are based on six fundamental criteria that address the quality of design and craftsmanship.
- Criterion A: The relationship between form, use, and construction.
- Criterion B: The relationship with the environment, requiring the object to 'stand well' within its urban or landscape context.
- Criterion C: Meanings of forms in a socio-cultural context, including heritage values and associations.
- Criterion D: The balance between clarity and complexity to ensure visual structure without loss of appeal.
- Criterion E: Scale and proportions, specifically the ratios of the hull, superstructure, and deck areas.
- Criterion F: Material, texture, color, and light, supporting the character of the object and its surroundings.
Technical Standards for Ships in the Canals
For ships located in the historic Grachten system, the document mandates specific dimensional and material constraints to preserve the city's character.
- Superstructure limits: The combined length of the roef (cabin) and stuurhut (wheelhouse) may not exceed 30% of the total ship length.
- Wheelhouse size: The wheelhouse alone is restricted to a maximum of 15% of the ship's length.
- Height of installations: Exhaust pipes may not protrude more than 1.00 meter above the roof or deck.
- Solar panels: Must be placed flat on the roof, keeping a minimum distance of 0.30 meters from the roof edges.
Frequently Asked Questions
Are solar panels allowed on houseboats in Amsterdam?
Yes, solar panels are permitted but must be installed flat on the roof of the wheelhouse or cargo hold. They must be arranged in a single line and maintain a minimum clearance of 0.30 meters from all roof edges.
What are the rules for exhaust pipes on floating structures?
In most spatial systems, including the canals and harbors, exhaust pipes must not stick out more than 1.00 meter above the roof or deck level.
Can I install a satellite dish on my boat?
Satellite dishes are allowed if they are modest in size and executed in a restrained color scheme. On ships, they should ideally be placed at the rear of the wheelhouse.
What materials are allowed for new superstructures in Weesp?
For houseboats in Weesp, superstructures must be made of wood, steel, or glass. The use of brick, plastic, or concrete for the mass of the superstructure is prohibited.
What is the maximum height for a 'koekoek' (skylight) on a ship?
A koekoek installed on the roof of a ship's superstructure must be placed on the longitudinal axis and have a height of no more than 0.25 meters.
How are historic ships assessed for heritage value?
Assessment focuses on maintaining the authentic hoofdvorm (main form), original materials, and characteristic parts like the berghout, boeisel, and zijzwaarden. Preservation is prioritized over reconstruction.
