From sash window restoration to full Grade II refurbishment — sensitive, period-appropriate restoration of London's historic homes. Free site visits.
London has some of the finest period housing stock in the country. Restoring it properly means knowing when to preserve, when to repair, and when to replace like-for-like. TrustBuilt Projects works on Victorian, Edwardian and Georgian properties — including listed buildings and conservation areas.
We specialise in keeping original features intact wherever possible — cornices, ceiling roses, fireplaces, sash windows, original plasterwork, panelled doors — while bringing modern services and comfort up to current standards. Every project is quoted transparently after a free site visit.
We visit your property, measure up, listen to your vision, and ask the right questions about what you need.

Grade II or conservation-area constraints require conservation-officer approval and like-for-like methods, adding 8–16 weeks and 15–40% to standard renovation costs.
Lime plasterers, sash joiners and ornamental plasterers are in short supply and charge higher day rates than general builders, pushing London prices up.
A repairable sash overhaul costs far less than replacing a rotten box sash with a full made-to-measure hardwood or Accoya window.
Breathable lime mortar and plaster cost 30–60% more than modern cement and gypsum, and cure slowly — but cement on solid walls traps damp and damages original fabric.
Lath-and-plaster, dry rot, failed cement repairs and damp behind period walls are common and only surface on opening up — budget 10–15% contingency.
Restricted terraced access, scaffold and parking permits, skip hire and borough rules add a 20–40% London premium over UK national averages.

Yes. We've completed restoration work on numerous Grade II listed properties in London. Listed building consent is required for any alterations to a listed structure — we'll guide you through the application process and work to the conservation officer's requirements.
Every restoration is priced individually — it depends on the size of the house and the depth of work, from a single sash window or room to a full Victorian house restoration. Free quote after a site visit.
Yes — this is far better than replacement for period properties (and required for listed buildings). We strip down the sash, install discrete brush seals, repair any rotten timber with proper splicing, repaint, and reinstall. Cuts heat loss dramatically while preserving the original window.
Yes. Period properties (especially pre-1919) need lime mortar, not modern cement — the building needs to breathe. We use lime mortar for brickwork pointing, lime plaster for walls, and traditional finishing materials where appropriate.
Absolutely — many of our period restoration projects include modern services. The skill is integrating them sympathetically: routing pipes through existing voids, hiding cabling within mouldings, designing en-suites that fit the period aesthetic. Underfloor heating works particularly well in restored period flooring.
Applications are submitted to your local Borough's Conservation Officer. We work closely with these departments and can guide you through the process. Some local heritage-experienced architects are essential for complex jobs — we can recommend trusted ones.
Yes — most of central London is covered by conservation area designations. Even if your property isn't individually listed, conservation area rules can restrict what you change externally. We know the rules and work within them.
