“Greg's attention to detail and dedication elevated both the experience and the result - he certainly knows his way around a tile. In addition to the bathroom refit, Cormac replaced all the plastic switches, sockets and pull-cords in the house with brushed brass. Highly recommended and will certainly work with the Buildaway team again…”

His team worked extremely hard and a big shoutout to Greg for his attention to detail!

Frequently Asked Questions
Your questions about home extensions in Pimlico, answered.
How much does a home extension cost in Pimlico?
As a guide, a home extension in Pimlico (SW1V) runs roughly £40,000–£60,000 for a single-storey rear, £60,000–£80,000 for a larger or wrap-around scheme, and £100,000+ for double-storey work. UK build costs sit around £1,800–£3,000 per m², and London consistently lands at the upper end. Buildaway fixes your figure in a written quote after survey.
How long does a home extension take in Pimlico?
Allow roughly 12–20 weeks of build in Pimlico, depending on scheme. The programme most people forget is before that: design, Westminster City Council approval and party-wall awards can add 3–4 months to a SW1V project. Buildaway runs those in parallel and gives you a realistic combined timeline up front.
Do I need planning permission for an extension in Pimlico?
Sometimes yes, sometimes no. In Pimlico, permitted development can cover a modest rear extension, but Westminster City Council takes a close view on anything altering the street elevation, and heritage designation around St George's Square and Dolphin Square removes the easy route. Buildaway checks planning, party-wall and freeholder position together.
What types of extension do you offer in Pimlico?
All the usual types: single-storey rear, side-return, wrap-around, double-storey and basement work. In Pimlico the choice is set by the plot and the planning position, not preference. Buildaway measures the SW1V site and boundary first, then advises honestly on what is achievable.
Do Buildaway handle both design and construction for Pimlico extensions?
Yes - design, planning and construction under one Buildaway contract in Pimlico. That single accountability is the main reason our SW1V extensions finish on the dates we committed to.
Are your extension specialists local to Pimlico?
Buildaway covers Pimlico and the wider SW1V area year-round. Having extended this housing stock around St George's Square and Dolphin Square repeatedly, we know its constraints before the survey - and we are nearby well after handover.
