What does our architect service include?

Our architect service across London covers a comprehensive range of work, tailored to the specific requirements of each property. Whether you need planning applications as part of our architect service. We also handle permitted development as part of our architect service. Our team provides expert listed buildings as part of our architect service. This includes comprehensive extension design as part of our architect service. We cover all aspects of loft design as part of our architect service. Our ARB-registered architects specialise in residential projects across NW London. From planning applications and permitted development assessments to full architectural design and contract administration, we provide a complete architectural service. Every job begins with a thorough assessment so we understand the full scope before quoting, and we use quality materials suited to the age and character of your property. We do not cut corners or use cheap substitutes — the materials we specify are chosen for durability, appearance, and compatibility with your home. If a job requires specialist skills or equipment, we have them in-house rather than subcontracting to unknown third parties. For London properties — many of which are Victorian, Georgian, or Edwardian — this attention to detail and material selection makes a real difference to the quality and longevity of the finished work.

Areas we cover for architect

We provide architect across London, covering North, Central, and South West London. Our core service area remains NW3 (Hampstead, Belsize Park, Swiss Cottage, Frognal), NW6 (West Hampstead, Kilburn, Brondesbury), and NW8 (St John's Wood, Maida Vale, Hamilton Terrace), but we now serve homeowners throughout a much wider area. In North London, we work in Highgate, Primrose Hill, Dartmouth Park, Highbury, and Canonbury. In Central London, we cover Mayfair, Fitzrovia, Belgravia, Knightsbridge, Bloomsbury, Paddington, Bayswater, and Westminster. In South West London, our team serves Chelsea, South Kensington, Kensington, Fulham, Battersea, Putney, Richmond, Barnes, and Hammersmith. Each area has its own property characteristics and conservation area considerations — select your area above for local architect information, typical pricing, and current availability specific to your neighbourhood. We understand the particular characteristics of London properties in each area — from the grand stucco-fronted houses of Belgravia to the red-brick Victorian terraces of Battersea — and tailor our approach accordingly.

When to call us for architect

Not sure whether you need professional architect? Here are some common situations where London homeowners call us. — You want a feasibility study before committing to a major renovation. — You need professional drawings and plans for a planning application. — You want an interior designer to help you make the most of a space. — A structural issue needs a qualified engineer’s assessment. — You are starting a renovation and need an architect to lead the design. — Party wall agreements are required before building work can begin. Bear in mind that some architect issues are seasonal. Autumn and winter bring increased demand for heating-related work and weather damage repairs, while spring and summer are peak times for renovation projects and outdoor work. Booking early in the season often means shorter wait times. If your situation does not match any of these exactly, contact us anyway — we are happy to advise over the phone or by WhatsApp, and there is never any obligation to proceed. We would always rather you asked and got honest advice than delayed and let a problem escalate.

What to expect from our architect service

When you engage us for architect, the process is collaborative and transparent. We start by listening — understanding how you use your home, what you want to change, and what constraints apply. For period properties, we research the building's history and any heritage designations. We then develop initial concepts, present them for your review, and refine the design based on your input. Planning and building regulations applications are managed on your behalf. Throughout the process, we keep you informed on progress, timescales, and costs. Our aim is to deliver a design that works practically, looks right for the property, and meets all regulatory requirements. We treat every property with respect — shoes off or covered, dust sheets down, and everything cleaned and tidied before we leave. Our aim is that the only evidence of our visit is the completed work itself.

Architect pricing & costs

The cost of architect in London depends on the scope of work, the property type, and any specific materials or access requirements. Typical project costs range from £2,000–£20,000. We provide free, no-obligation quotes for all architect work. Every quote is fixed-price — the amount we quote is the amount you pay, with no hidden extras, call-out fees, or surprises. Property type has a significant impact on pricing. Victorian terraces and Georgian townhouses often require specialist materials and careful handling of original features, while modern apartments may involve different access and compliance considerations. Properties in conservation areas may carry a small premium to account for the additional planning requirements and heritage-appropriate materials and techniques. London pricing reflects the quality of tradespeople, insurance, and materials required to work to a high standard in the capital. For larger projects, we can break work into phases with clear pricing for each stage. Payment is by bank transfer after completion for standard jobs, or by deposit and staged payments for larger works. We never ask for full payment upfront, and we are always happy to walk you through the quote line by line so you understand exactly what you are paying for.

Our architect process

Getting architect sorted through Hampstead On Demand follows a simple four-step process. First, submit your request — tell us what you need, upload photos if you have them, and indicate your preferred timing. Second, we review your request and provide a detailed, fixed-price quote, typically within a few hours. Third, once you approve the quote, we schedule the work at a time that suits you. Finally, our team completes the work to our standards, cleans up, and follows up to make sure you are satisfied. Every job comes with our 12-month workmanship guarantee. For members, repeat requests are even simpler — we already have your property details and history on file, so there is less to explain each time.

Property types we work with for architect

London’s housing stock is remarkably diverse, and our architect service is equipped to handle all of it. The approach, materials, and techniques we use depend entirely on the property — a blanket method that ignores the building’s age, construction, and character leads to poor results. We regularly work with: Mews houses with their compact footprints, limited access, and often complex structural histories from their original use as carriage houses. Victorian terraces with their bay windows, decorative plasterwork, and original timber floors — require tradespeople who understand how these buildings move and breathe. Georgian townhouses with their symmetrical proportions, sash windows, and lime plaster walls — demand respect for traditional materials and construction methods. Edwardian semi-detached homes with their generous room sizes, picture rails, and Arts and Crafts detailing — benefit from tradespeople who can match existing features. Mansion flats and mansion blocks with their high ceilings, communal areas, and often strict management company requirements — need contractors experienced in block-managed properties. Each property type presents its own set of challenges and opportunities. Period properties often have hidden complexities — lath and plaster walls, lime mortar, lead pipework, or non-standard structural arrangements — that require experience to handle correctly. Whatever your property type, our team adapts its approach to suit the building, because what works in a new-build apartment is rarely appropriate for a Grade II listed townhouse.
