FAQs


Do I need planning permission in Whetstone?

Yes. Most extensions, loft conversions, and new-build schemes require formal consent from Barnet Council.


Can I build on a backland or infill site?

Yes, but planning is complex. We specialise in maximising site potential while navigating access, privacy, and massing constraints.


Is basement development allowed?

Yes, though Barnet applies strict structural and hydrological checks.


Do you work with developers as well as homeowners?

Absolutely. From bespoke homes to small multi-unit schemes, we balance design ambition with commercial value.


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. From insulation and airtightness to discreet renewable systems, we design for energy efficiency without compromising aesthetics.


Are you only Whetstone 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! 😍
