Not legal advice. Checked against bygningsreglementet.dk and its vejledning on kapitel 8/20/23. The popular guides disagree with each other: jmkiil makes 50 m² a condition of building in skel, Bolius ties it only to permits, and Davidsen contradicts itself. The regulation backs Bolius.
Pederstrupvej 24, Odense — byzone, no lokalplan. Verified on Plandata.dk: none adopted, proposed or historic, so the BR18 byggeret is the whole framework. Kommuneplanramme 44.B.2 Korup By allows 30% and 2 storeys and says nothing about roof form, materials, colour or secondary buildings. Byzone also means no landzonetilladelse. Plans change — recheck before applying.
§ 180 is what puts a carport under this at all. Stk. 1 makes it answer to §§ 176 and 177, the same byggeret as a house; stk. 2 then permits going nearer than 2.5 m to vej and skel if § 181 is met. So § 181 is a permission with a price, not a prohibition.
Heights are measured from natural terrain, as assumed by the kommune at the original permit — later digging does not move it. Under § 456, stk. 3 the kommune can omit a niveauplan for a building inside the 8.50 m plane at every point, and this is at about 4 m. The model assumes level ground.
