FAQs


Do I need planning permission in Belsize Park?

Almost certainly. Most of NW3 and NW6 falls under Conservation Areas or Article 4 restrictions, meaning even small exterior changes need formal approval.


Can I extend a listed property?

Yes — with care. Listed building consent can be secured for sensitive additions, internal reconfigurations, and basement works when they’re well-designed and justified.


Is basement development possible?

Yes it is, but Camden applies strict structural and environmental controls. We manage these with early technical input and comprehensive supporting documentation.


Do you work with developers as well as homeowners?

Absolutely. From boutique multi-unit schemes to mixed-use developments, we balance commercial viability with design excellence to achieve planning success and strong ROI.


How long does planning take?

Typically 8–12 weeks, though more complex heritage or multi-unit schemes may require additional consultation time.


Can you integrate sustainability upgrades?

Yes. We discreetly incorporate energy-efficient systems, improved insulation, and renewable technologies that respect the area’s architectural character.


Are you only Belsize Park Architects?

No. We operate in many North London areas and surrounding areas, see them here. We also sometimes go further if you have a project that is intriguing – let us know.

Dor has been incredible to work with on our renovation. He is extremely thorough, very reachable, attentive to detail, and really listens. He and his team put extra care into their work and come to the table organised with well-thought-out questions. We feel we’re in safe hands moving into construction because everything has been planned to such detail ahead of time, with clear direction, problem-solving, and great communication between all teams involved. For any future project, we’re definitely coming back to Dor! 😍
