Beeldkwaliteitsplan Groenewei – Meerstad Building Quality and Aesthetic Guidelines
The Beeldkwaliteitsplan Groenewei is an official regulatory document issued by the Gemeente Groningen for the development of the Groenewei residential district within the Meerstad expansion area. Dated January 15, 2019, this framework functions as a binding extension of the Welstandsnota 2018 (Aesthetic Guidelines) for the municipality of Groningen. It serves as both an inspiration for architects and a primary assessment document for the municipal beauty committee (welstandcommissie) to ensure architectural coherence and spatial quality.
The document governs urban design principles, architectural forms, and ecological integration. Its regulatory scope covers distinct residential spheres including the Parkwand, Landschappelijke lijst (landscape border), Groene hoven (green courtyards), and Dorpse straatjes (village streets). Structured into five main chapters, the plan details general neighborhood-wide rules (Chapter D) and location-specific regulations (Chapter E). It defines concrete thresholds for building heights, plot coverage percentages, set-back distances, and specific material palettes including brick types and roof treatments.
This regulatory framework establishes the transition between the urban environment and the natural landscape of Park Meerstad and the Woldmeer lake. The following sections provide the technical standards for plot layout, building volumes, and sustainability requirements as defined in the official plan.
Plot Layout and Building Density
The plan prescribes strict limits on building placement and the maximum gross ground-floor area to maintain openness within the district.
- Detached houses: Maximum 30% plot coverage, with a main building maximum of 200m2.
- Semi-detached houses: Maximum 45% plot coverage, with a main building maximum of 150m2.
- Row houses: Maximum 55% plot coverage, with a main building maximum of 100m2.
- Patio houses: Maximum 75% plot coverage, with a main building maximum of 175m2.
- Set-backs: Row and patio houses must be set back at least 3m from the property line; detached and semi-detached houses require a minimum 5m set-back.
Building Volumes and Roof Guidelines
Architectural forms are restricted to simple rectangular main volumes with either flat or pitched roofs to ensure neighborhood cohesion.
- General heights: For pitched roofs, the maximum gutter height is 7m and the maximum ridge height is 13m.
- Roof pitch: Transverse roofs must have a minimum pitch of 50 degrees; longitudinal roofs require at least 30 degrees.
- Flat roofs: Maximum gutter height is 7m, though an extra floor is permitted up to 10.5m if it covers no more than 60% of the main volume's footprint.
- Architectural ensembles: Main buildings, extensions, and outbuildings must be designed as a single architectural unit.
Material Palette and Detailing
The use of materials is limited to a specific range of warm, earth-toned colors to prevent visual fragmentation.
- Façades: Entirely constructed in brick using earth colors between red and brown; joints must match the brick color or be dark grey.
- Roofing: Sloped roofs must use anthracite ceramic tiles, slate, or green roof systems (mos/sedum).
- Openings and trims: Window frames and roof edges are limited to white (RAL 9010) or anthracite (RAL 7016).
- Solar integration: Solar collectors must be integrated into the roof design and remain invisible from the street on flat roofs.
The Parkwand Special Zone
The Parkwand acts as the face of Meerstad along the Vossenburglaan, requiring a higher level of architectural ambition.
- Height requirements: Ground-bound houses in the Parkwand must have a gutter height between 7m and 10m and a ridge height between 12m and 15m.
- Floor level: The ground floor must be situated approximately 680mm above the sidewalk level.
- Appartement buildings: Flat-roofed apartment blocks have a maximum height of 16m, with the third floor and above requiring a 1m set-back from the lower façade.
Sustainability and Ecology
Groenewei is designed as a gas-free district with specific mandates for nature-inclusive construction.
- Nesting facilities: Every house must integrate at least two nesting provisions for birds or bats within the façade or roof.
- Green borders: Boundary fences facing public space must consist of haagbeuk (hornbeam) hedges, maintained at a height of 1m in front yards and 1.6m to 2m in side/back yards.
- Technical installations: Heat pumps and other technical systems must be concealed from public view.
Frequently Asked Questions
What is the minimum number of parking spaces required per house?
Detached, semi-detached, and row houses must provide at least 2 parking spaces on their own plot, excluding the garage.
What are the allowed colors for brick façades in Groenewei?
Brickwork must be in warm earth tones ranging between red and brown, avoiding bright or overly pale colors.
Are flat roofs allowed in the Groenewei district?
Yes, flat roofs are permitted with a maximum gutter height of 7m, and an additional floor is possible if it covers no more than 60% of the footprint.
What are the specific material requirements for the Landschappelijke lijst?
Façades in this zone must be constructed entirely or substantially from wood, finished in its natural color or black stain.
Is the use of natural gas permitted for new builds in Groenewei?
No, the district does not have a gas network and utilizes sustainable energy solutions like heat pumps and solar collectors.
What is the maximum ridge height for standard houses?
The maximum ridge height for main buildings with a pitched roof is 13 meters, measured from the ground level.
How high must the boundary hedges be in front gardens?
Hedges along the front garden boundary must be hornbeam (haagbeuk) and reach a height of approximately 1 meter when fully grown.
Are solar panels allowed on flat roofs?
Yes, but they must be integrated into the architecture and remain invisible from the street, for example by using a parapet wall.
