Planning permission drawings, mansion block reconfigurations, heritage-sensitive extensions, and building regulations for Swiss Cottage's Edwardian and Victorian housing. MCIAT chartered, fixed fees, Camden conservation expertise built in.
Swiss Cottage sits in the NW3 postcode within the London Borough of Camden, south of Hampstead and west of Primrose Hill. The neighbourhood's substantial Edwardian mansion blocks, Victorian villas, and high-value terraces make it one of London's most valuable — and tightly controlled — residential markets.
Mansion blocks: Much of central Swiss Cottage is mansion block. Flat reconfigurations, new bathrooms, open-plan kitchen-living rooms, and balcony additions require planning permission, freeholder consent, and Building Regulations approval. Our drawings meet Camden's standards and typical freeholder requirements.
Fitzjohns/Netherhall Conservation Area: This CA covers the handsome Victorian and Edwardian streets around Swiss Cottage. Article 4 Directions restrict PD rights. Heritage Statements are required for most applications. Our team prepares conservation-grade submissions.
Basement works: Camden's basement policy is among the strictest in London. Subterranean developments must meet specific tests on hydrology, structural impact, and size. We prepare compliant schemes with full structural and hydrological input.
Victorian and Edwardian villas: Swiss Cottage has substantial detached villas suitable for extensions and loft conversions. All require planning permission in the CA. We design heritage-sensitive schemes.
