You're not short of options. You're short of certainty.

Every homeowner in West London thinking about a loft conversion hits the same wall. You get quotes that vary by £20,000. You’re told “it depends” when you ask about planning. One company disappears after the survey. Another hands you off to a project manager you’ve never met.

You don’t just want a loft conversion. You want to know exactly what you’re getting, who’s doing it, what it will cost, and that it will be finished properly.

That’s what we built our business around.

One team. From planning to handover.

We don’t quote the structure and hand you a list of extras. Everything is covered, in writing, before we start.

🔒

Fixed-Price Contracts

The price we quote is the price you pay. Itemised, in writing, before any work starts. No ‘while we’re at it’ surprises halfway through.

👷

One Team, Start to Finish

The people you meet at survey are the people who build your loft. No handoffs to strangers. No site manager you’ve never spoken to.

Common questions before most loft conversions.

Most loft conversions in West London fall under Permitted Development rights — meaning no full planning application is required. However, if your property is in a conservation area, is a flat, is listed, or if previous extensions have used up your permitted development allowance, a full application may be needed. We check all of this at the free site survey and tell you exactly where you stand.
A standard Velux conversion typically takes 4–6 weeks on site. A dormer runs 8–12 weeks. A mansard or hip-to-gable conversion, which involves more structural work, typically runs 10–14 weeks. We give you a realistic programme in the written proposal, built around building control inspection milestones — so there’s no artificial pressure.
In most cases, no. The majority of structural and roofing work happens above the existing ceiling line. The most disruptive phase is when the staircase is cut in — we give you advance notice and plan carefully around it. If a particular phase of your project genuinely makes it easier to be away for a few days, we’ll tell you honestly.
As a rough guide, 2.2 metres or more at the highest central point gives a good chance of a practical conversion. If you can stand upright in your loft at the centre, it’s worth a survey. We measure properly at the site visit and give you a definitive answer.
In West London, adding a bedroom through a loft conversion typically adds 15–25% to property value, depending on the street and finish quality. More practically, it’s often the most cost-effective way to gain a bedroom — significantly cheaper per square metre than buying a larger property in the same area.
We work exclusively across West London — W1 to W14, and TW, SW and KT postcodes including Ealing, Chiswick, Hammersmith, Kensington, Fulham, Richmond, Twickenham, Hounslow, Acton and surrounding areas. If you’re just outside this, ask us anyway.
