The Problem with Separate Firms
Hire an Architect. Then an Engineer. Then a Builder.
- Architect designs without knowing build costs
- Weeks waiting for structural calcs to come back
- Builder says “this won’t work” — back to the drawing board
- Nobody accountable when things go wrong between firms
- Budget inflates with variation orders and extras
- You become the project manager — coordinating everyone
One Studio. One Contract. One Accountable Team.
- Architect and engineer design together from day one
- Structural calcs in days, not weeks — same office
- Build team involved in design — everything is buildable
- One firm responsible for everything — no finger-pointing
- Fixed-price contract — the quote is the final cost
- We manage every trade, every phase, every detail
Everything Under One Roof
At 250 Finchley Road you will find what no other London practice offers. Our RIBA chartered architects, structural engineers, interior designers and planning consultants work from the same studio — meaning design decisions, structural solutions and construction methodology are resolved together in days, not weeks of correspondence between separate firms.
Alongside our design-and-build practice, our RICS regulated sister company — Hampstead Chartered Surveyors & Building Consultancy — operates from the same address, providing pre-acquisition surveys, party wall services, pre-application advisory, residential project management and independent development monitoring. This means clients have access to chartered surveying expertise from feasibility through to final handover, all coordinated under one roof.

Built on Reputation, Sustained by Results
Hampstead Renovations was founded on a simple principle: London homeowners deserve better than the traditional model of hiring an architect, then an engineer, then a builder — and hoping the three can work together. We assembled every discipline under one roof so that design, structure and construction are resolved as one conversation, not three separate invoices.
Our directors bring decades of combined experience across high-end residential projects — from Grade II listed Georgian townhouses in Belgravia to contemporary basement dig-downs in Belsize Park. That depth of experience is embedded in every project we take on, with a director personally involved from first consultation to final handover.
I would like to thank Ross and his team for their consistent commitment to quality and their unerring reliability. They delivered our property to specification and on time, proving to be an extremely effective, experienced, and proactive contractor.
We have worked with Ross and his company many times. They are extremely professional and hardworking individuals who can work under any circumstances. There was no variation to the works.
A company where you get value for your money while at the same time achieving excellent quality. Their work is carried out on time and within budget. We’ve worked with them on multiple projects and they never disappoint.
Book Your Free Design Consultation
We limit our intake to ensure director-level involvement on every project. A consultation assesses your property's potential, planning constraints and realistic budget — completely free.
“How do I know your quote is fair?”
We break down every cost line-by-line: materials, labour, professional fees, contingency. No lump sums, no hidden margins.
“How long will my project take?”
Typical rear extension: 12–16 weeks. Loft conversion: 8–12 weeks. Fixed programme with weekly milestones.
“What if something unexpected is found?”
We include a 10% contingency for unknowns. If we don’t use it, you don’t pay it.
“Do you handle planning?”
Yes — in-house architects manage all applications. 97% approval rate across London.
“Do I need planning permission for an extension?”
It depends on the size and your property type. Many rear extensions fall under Permitted Development, but conservation areas and listed buildings usually require full planning. We assess this at the first visit.
“What does a party wall agreement involve?”
If your build is on or near a shared boundary, a Party Wall Act notice is served to neighbours. We manage the full process including surveyor appointment and schedule of condition.
“How much does a typical loft conversion cost?”
In London, a dormer loft conversion typically ranges from £65,000 to £120,000 depending on size, finish level and structural requirements. We provide a fixed-price quote after survey.
“Can you work on listed buildings?”
Yes. Our heritage team has completed over 40 listed building projects. We handle Listed Building Consent applications and work to conservation officer requirements.
“Do you offer a warranty?”
Every project comes with a 10-year structural warranty plus 2 years on fixtures and finishes. We also carry £10M professional indemnity insurance.
“Can I stay in my home during the build?”
For most extensions and loft conversions, yes. We phase the work to keep disruption minimal. Basement projects or full refurbishments usually require temporary relocation.
