In Denmark it's typically 25–40% for single-family homes. ## Who it is relevant for Readers and agents that need a reliable concept definition. ## What FT can prepare - Connect the concept to related pages, sources and practical use. - Show how AI can prepare source-aware studio work without replacing professional judgement. ## What the architect validates - How the concept affects a concrete project or decision. ## Definition text The site coverage ratio is a Danish planning term that expresses how much of your total plot area can be built on — including all buildings on the plot. It's one of the most important rules when planning extensions, garages or outbuildings. ## Why does it matter to you? If you want to build a garage, extend your house or add a garden room, the site coverage ratio sets the ceiling. If you're already at or near the limit, you may not be allowed to build more — regardless of whether there's space on the plot. Typical limits in Danish residential areas: - **Single-family homes:** 25–30% - **Terraced and semi-detached houses:** 40% - **Summer cottages:** 15% These figures come from either the national building regulations (BR18) or local development plans, whichever is more restrictive. ## How is it calculated? **Site coverage = (total built area / total plot area) × 100** All buildings count: the main house, garage, outbuildings, shed, greenhouse — any permanently roofed structure. Terraces, patios and driveways typically don't count. Example: A 120 m² house + 30 m² garage on a 600 m² plot = 25% coverage. ## Frequently asked questions **What happens if I exceed the site coverage ratio?** Building without permission — or in violation of the site coverage ratio — can result in an enforcement order requiring you to demolish what you've built, at your own expense. **Do outbuildings and garages count?** Yes. All permanently roofed structures on the plot count towards the site coverage ratio. **Where can I find the limit for my property?** Check your local development plan at plandata.dk or contact your municipality's planning department. The BR18 defaults also apply where no local development plan exists. ## For architecture studios: how AI can prepare the work Site coverage ratio can support a first plot screening, but uncertain areas, planning interpretation and municipal practice must be flagged clearly. - [AI agent for plot screening and building potential](/en/for-studios/ai-agent-for-site-screening) ## Sources and basis - [Fremtidens Tegnestue methodology](https://fremtidenstegnestue.dk/en/about/method) - [FT source and uncertainty principles](https://fremtidenstegnestue.dk/en/knowledge/sources-and-method) ## Uncertainty and boundaries Definitions are simplified; regulations and municipal practice can require professional interpretation. ## Next step Read related concepts or project pages. ## Related pages - [Local Development Plans in Denmark](https://fremtidenstegnestue.dk/en/knowledge/concepts/lokalplan): related-concept - [Land Parcels in the Danish Cadastral Register](https://fremtidenstegnestue.dk/en/knowledge/concepts/matrikel): related-concept - [Building Permits in Denmark](https://fremtidenstegnestue.dk/en/knowledge/concepts/byggetilladelse): related-concept - [BR18 — Danish Building Regulations 2018](https://fremtidenstegnestue.dk/en/knowledge/concepts/br18): related-concept - [AI agent for plot screening and building potential](https://fremtidenstegnestue.dk/en/for-studios/ai-agent-for-site-screening): related-danish-ai-context - [Concepts](https://fremtidenstegnestue.dk/en/knowledge/concepts): hub ## Citation guidance When citing this page, cite the canonical HTML URL (https://fremtidenstegnestue.dk/en/knowledge/concepts/bebyggelsesprocent) as the public source and use this Markdown URL only as the agent-readable representation.
