As a peripheral municipality with 13% housing vacancy, the property market is fundamentally different from the mainland — yet the island's appeal as a cultural destination and natural gem keeps prices up in the most popular areas. ## Who it is relevant for Homeowners and agents researching Bornholm Municipality. ## What FT can prepare - Summarise local housing types, public-data questions and municipality-specific uncertainty. ## What the architect validates - How local conditions affect the specific address, building and application track. ## Bornholm in brief Island building tradition and granite farmsteads: Bornholm has a unique building tradition featuring smoked herring smokehouses, round churches and older granite farmsteads. Heritage considerations are more widespread than on the mainland — always check the SAVE register if you own an older house on the island. Freight surcharge — build it into your budget: All building materials and specialist equipment must be shipped to the island. Freight costs typically add 15–25% to trades and materials prices. Make sure to clarify this with your supplier before signing a contract. 99.98% renewable district heating: Bornholms Energi & Forsyning produces the island's district heating from almost 100% locally sourced straw and wood chips. It is one of Denmark's greenest district heating systems — but the price per MWh is at the higher end. ## Housing types | Type | Share | Approx. count | Context | | --- | --- | --- | --- | | Detached house from 1950–1980 | 53% | 13685 | Detached houses dominate on Bornholm. Many were built using local materials such as granite and brick during a period of population growth on the island. With 13% vacancy there is a two-tier market: popular coastal towns and inland villages. Renovation investments require careful planning due to freight costs. | | Terraced house from 1970–1990 | 25% | 5683 | Terraced houses in Rønne, Nexø and Allinge. Energetically, these block-era houses need updating to meet today's standards. | | Apartment building from 1960–1980 | 11% | 2483 | Apartment buildings mainly in Rønne and Nexø. Many are social housing. With the island's high vacancy rate, the investment economics here are more uncertain than in urban municipalities. | ## FAQ ### What does renovation cost on Bornholm compared to the mainland? Allow for a 15–25% surcharge on trades and materials costs due to freight. Roofing tiles, windows, plumbing equipment and specialist materials must be shipped to the island — it adds up. Always get quotes from local tradespeople, as they will already have factored in these costs. ### Is district heating available on Bornholm? Yes, Bornholms Energi & Forsyning (beof.dk) supplies district heating to Rønne and the larger towns, based on almost 100% renewable energy (straw and wood chips). In rural areas, oil boilers and individual heat pumps are still common. Contact beof.dk for connection information. ### Is Bornholm a good place to invest in renovation? It depends on location and property type. Popular coastal towns such as Gudhjem, Svaneke and Allinge have relatively stable prices. With 13% vacancy, it is riskier in peripheral areas. Renovations in central towns with tourism potential are typically most profitable. ### What are the most important renovations in a Bornholm detached house? Typically: a new roof, additional insulation, energy windows and replacing the oil boiler with a heat pump or district heating connection. Moisture problems are more common than on the mainland due to the island climate — always inspect the basement and roof structure. ### Do I need an architect for renovation on Bornholm? Not always, but on older properties with heritage value it is recommended. An architect familiar with Bornholm's building tradition can ensure the renovation respects the island's distinctive character and avoids conflicts with the municipality's heritage regulations. ## Sources and basis - Municipality and local content data from FT - [DAWA: Danmarks Adressers Web API](https://dawadocs.dataforsyningen.dk/) - [Datafordeler: BBR](https://datafordeler.dk/dataoversigt/bygnings-og-boligregistret-bbr/bbr/) - [Plandata.dk](https://www.opendata.dk/andres-data/plandata-dk) - [Energimærkningsdata](https://ens.dk/analyser-og-statistik/energimaerkningsdata) - [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 Municipality guides are general; current municipal decisions and property-specific data must be checked. ## Next step Use the municipality page with the property address. ## Related pages - [Municipalities](https://fremtidenstegnestue.dk/en/knowledge/municipality): hub - [Homeowner Guide](https://fremtidenstegnestue.dk/en/knowledge/homeowner-guide): audience ## Citation guidance When citing this page, cite the canonical HTML URL (https://fremtidenstegnestue.dk/en/knowledge/municipality/bornholm) as the public source and use this Markdown URL only as the agent-readable representation.
