Architects, Engineers, Surveyors & Builders Under One Roof.
Surveyor-led refurbishment advice via Hampstead Chartered Surveyors →One Studio. One Contract. One Team.
We deliver Knightsbridge building projects with an integrated design-build team under one fixed-price contract - RIBA design, structural engineering, party wall coordination, procurement, directly managed site teams, Building Control, programme control and final handover through one accountable fixed-price contract.
In Knightsbridge the consent file is as much a builder's tool as the scaffold. The Regency and Victorian townhouses and prime mansion flats around Lowndes Square, Cadogan Place and Wilton Place are largely listed, largely leasehold, and among the most valuable homes in the country; the Cadogan and other estates hold much of the land within the Knightsbridge Conservation Area. In practice that means estate or freeholder consent and Licence to Alter requirements often run alongside planning and Building Regulations, and the consent strategy leads the project rather than following it.
The neighbours are part of the job too. Cost here is driven by high specification, RBKC-compliant basement works, acoustic separation in the mansion blocks, conservation-grade external work and party-wall awards with close, high-value neighbours — and in the prime mansion flats, some of London's most valuable leasehold homes, structure, acoustics and freeholder or estate consents are handled together so the exacting finish is never compromised by what sits behind it.
On budgets, the London-wide bands we quote from run £90,000–£180,000 excluding VAT for a cosmetic renovation of a three-to-four-bed house, £275,000–£475,000 for back-to-brick, and £60,000–£110,000 for a full two-bed flat refurbishment — with Knightsbridge specification typically pressing toward the top of each band.
What Our Building Service Covers
Hiring a builder should mean hiring one accountable team, not refereeing a chain of subcontractors. As a design-and-build practice we carry your project from drawings to handover under a single fixed-price contract, with the architect, engineer and site manager answerable to the same programme. The scope below covers most of the building work we are asked to price.
- Extensions — rear, side-return and wraparound additions, built weathertight before the existing house is opened up
- Loft & basement conversions — new storeys above and below, with steelwork and waterproofing engineered in-house
- Structural alterations — load-bearing wall removals, new openings and floor changes with calculations done before pricing
- Refurbishment — whole-house or single-floor upgrades sequenced so trades never queue behind each other
- Kitchens & bathrooms — first fix to final silicone, delivered by the same teams who built the rooms around them
- Mechanical & electrical — rewires, heating systems and ventilation installed and certified as part of the main contract
- Joinery & carpentry — doors, staircases, skirting and fitted furniture made to suit the age of the building
- External & facade works — brickwork, render, roofing repairs and landscaping tied into the main programme
How We Run Your Project
Six checkpoints between first phone call and final handover, each signed off before the next starts.
- Site visit & scope — we walk the property with you, test what the budget can realistically deliver and flag constraints early.
- Drawings & approvals — our architects prepare the design and handle whatever consents the work requires.
- Itemised fixed price — every trade, material and provisional sum listed line by line, so nothing is priced twice.
- Mobilisation — protection, welfare, neighbour notifications and deliveries organised before the first skip arrives.
- The build — structural work, first fix, second fix and finishes run by a dedicated site manager you can reach directly.
- Handover — a walked snagging inspection, full certification pack and aftercare contact once the site is cleared.
Almost all building work of this scale needs Building Regulations approval — structural openings, electrics, drainage, heating and fire safety are each inspected and certified through building control, which we manage on your behalf. Where the works cut into, bear on or excavate near a wall shared with a neighbour, the Party Wall etc. Act 1996 obliges you to serve notice before starting, and we coordinate the surveyors so the programme is not held hostage to it. Our planning guide library sets out what applies borough by borough.
Why Hampstead Renovations
The word “builder” covers everything from a van and a ladder to a full construction practice, so credentials matter. Ours: design by our in-house RIBA Chartered Architects, structural calculations from our own chartered structural engineers, and RICS surveying support through our sister company, Hampstead Chartered Surveyors, for party wall and condition matters. Every project runs on a fixed-price JCT contract, carries £10M public liability insurance, and is backed by a 12-month defects period plus a 10-year workmanship warranty. Enquire before 2pm on a weekday and we will call you back the same day.
Builders in Knightsbridge: Questions
Which consents does a building project in Knightsbridge need?
Usually a stack of them. Estate or freeholder consent and Licence to Alter requirements often run alongside planning and Building Regulations here — estate and freeholder consent runs in parallel with the council's decisions, and flats need a Licence to Alter before work starts.
What makes building work in Knightsbridge different from the rest of London?
The combination of value and control. The townhouses and mansion flats are largely listed, largely leasehold and among the most valuable homes in the country, and cost is driven by high specification, RBKC-compliant basement works, acoustic separation in mansion blocks, conservation-grade external work and party-wall awards with close, high-value neighbours.
Do you build inside Knightsbridge mansion blocks?
Yes — it is a discipline of its own. The prime mansion flats are among London's most valuable leasehold homes, and we handle structure, acoustics and freeholder or estate consents together for an exacting finish; flats need a Licence to Alter alongside any planning decisions.
Which Knightsbridge streets and building types do you work across?
Lowndes Square and Cadogan Place carry grand stuccoed and red-brick terraces; Wilton Place and Montpelier Square hold elegant Regency and Victorian houses; and the great mansion blocks provide some of London's most valuable leasehold flats — Regency townhouses, estate-owned terraces and prime mansion flats are the typical stock.
What should we budget for building work in Knightsbridge?
As London-wide bands excluding VAT: £90,000–£180,000 for a cosmetic renovation of a three-to-four-bed house, £275,000–£475,000 for a back-to-brick renovation, and £60,000–£110,000 for a full refurbishment of a two-bed flat. We firm those into a scheme-specific figure once consents and specification are scoped.
How do you differ from a standalone builder in Knightsbridge SW1X / SW7?
Most builders in Knightsbridge subcontract design, structural engineering and planning — leaving you managing four to six separate firms with overlapping responsibilities and gaps where things get dropped. We are one practice with every discipline in-house: RIBA chartered architects, surveying support through Hampstead Chartered Surveyors, IStructE chartered engineers and our own build teams. That means one contract, one point of responsibility, one fixed price. When an issue arises on site — a hidden beam, a changed specification, a neighbour request — it is resolved inside our office, without finger-pointing between separate firms with conflicting commercial interests.
