This site checks and explains; it sells nothing. When you need the work itself done, it goes to one of two independent practices — which one depends on whether the job is about designing and consenting the scheme, or about the building's condition, your neighbours and the lease.
The architect's door: designing the scheme and getting it consented — drawings, the planning application and the building-regulations package.
- Residential design for extensions, lofts, basements and conversions
- Planning applications, pre-application advice and appeals
- Lawful development certificates
- Building-regulations and technical design drawings
- Conservation-area design and listed building consent applications
The chartered-surveyor door: professional judgement on condition, risk, party wall matters and leasehold process.
- Building surveys, RICS home surveys and defect diagnosis
- Party wall matters and awards
- Technical due diligence before a purchase
- Leasehold and major-works advisory (Section 20)
- Dilapidations and building pathology
Both practices are independent and separately regulated — Hampstead Chartered Surveyors & Building Consultancy is an RICS-regulated firm (Firm Reg. 923064); Hampstead Architecture and Planning are ARB-registered architects. We publish no fees for their work: each quotes directly for the job in front of them. Your enquiry goes to the practice you choose — we never pass your details to builders or other third parties.
