Having the Beams team on hand to manage the project and provide extra reassurance on build decisions was incredibly helpful and made the whole experience stress free.

They have been extremely efficient and reassuring. It was a complex project but they took it all in their stride. They recommended very good contractors who were all punctual, polite and capable.

All about trust. I felt comfortable with my money, my project, and my home knowing that the outcome would be to my satisfaction or would be made good.

Renovate your whole home in Westminster with confidence
Westminster's housing stock is as varied as anywhere in London, from Georgian terraces in Pimlico and Belgravia to mansion blocks in Marylebone and period townhouses tucked behind Maida Vale's canals. A full home renovation across any of these needs a team who understands how the building is put together before work starts, not after walls are opened up.
That is why Beams puts structured project management at the centre of every whole-home renovation in Westminster. You get a single point of contact, a proper design and scope of works before any pricing is fixed, and a vetted local builder who has worked on similar properties, so the plan matches the building rather than the other way round.
One team, one plan
Managing a whole-home renovation usually means juggling an architect, a builder, and a design team who don't always talk to each other. Beams brings design and build together under one roof, so the same team that designs your renovation is accountable for delivering it.
That means one point of contact from your first estimate through to snagging, a design that has been checked for buildability before it is priced, and a fixed-price contract that reflects exactly what was designed, with no surprises when the build starts.
What a home renovation costs in Westminster
Westminster is one of London's most expensive property markets, and renovation costs here often sit toward the higher end of typical London ranges, reflecting higher labour and material costs in central London, tighter site access on many streets, and the additional care that period and listed buildings require.
The figures below are estimate ranges only, not fixed quotes. Based on Beams' experience of London home renovation projects, your actual cost will depend on the size and condition of your home, the specification you choose, and whether any structural or planning work is involved.
Project scope | Estimated cost range |
|---|---|
Single-floor refresh (decorative refurbishment) | £30,000 - £60,000 |
Full flat or house refurbishment | £70,000 - £150,000 |
Larger house renovation including some structural work | £150,000 - £300,000 |
Top-end whole-house renovation with extension or basement | £300,000+ |
How it works
Free estimate: Tell us about your project and get a free, no-obligation estimate and a first design call.
Design and scope: We create a full home design with a detailed scope of works, so everything is agreed before you commit.
Fixed-price build: Your vetted builder delivers the project to a fixed price, with milestone payments and a 12-month warranty.
Designed and specified properly
A renovation is only as good as the detail behind it. Vague specifications are one of the biggest causes of cost increases and disputes once a project starts on site.
That is why every Beams project includes a detailed scope of works and specification before pricing is fixed, covering everything from structural details to finishes, fixtures and fittings. This protects you from scope creep and gives your builder a clear brief to price and build against.

£6m public liability insurance: Every project is covered by public liability insurance.
Why renovate rather than move
Moving home in Westminster means stamp duty, estate agent fees, and the cost and disruption of finding a new property in one of London's tightest markets. Renovating lets you stay in the area and the community you know, while reshaping your home to suit how you actually live.
A well-planned renovation can also make better use of the space you already have, whether that is opening up a ground floor, reconfiguring bedrooms and bathrooms, or making more of a loft or basement, without the cost and upheaval of moving.
Renovating a home in Westminster
The average house price in Westminster was £877,000 as of July 2026, according to provisional ONS and HM Land Registry figures, reflecting the strength and premium nature of the borough's property market. That value makes getting a renovation right, both in quality and in planning terms, particularly important.
Much of Westminster falls within one of the borough's 56 conservation areas, and some conservation areas and individual streets also carry an Article 4 Direction, which removes certain permitted development rights. In practice, this means full home renovation and refurbishment projects in Westminster more often need full planning permission for anything beyond internal, like-for-like work than they would elsewhere. We work with homeowners across Westminster, and into neighbouring Hammersmith and Fulham, to navigate this properly from the start.
