Period mansion flats are some of London's finest homes — and some of its most demanding to refurbish. We deliver mansion block refurbishment with the freeholder approvals, acoustic compliance and protected-building logistics handled, restoring period detail while bringing services up to modern standard.
A mansion block flat is a particular kind of project. These Victorian and Edwardian buildings have generous proportions, original joinery, plaster and fireplaces worth preserving, but also ageing services, strict freeholder and managing-agent regimes, and shared structure that makes acoustic and fire separation critical. A successful mansion block refurbishment balances three things at once: sensitive restoration of period character, a full upgrade of services and layout, and disciplined compliance with the building's rules and the lease. That is exactly the kind of multi-disciplinary project our one-contract studio is built for.
Cornicing, panelled doors, fireplaces, sash windows and parquet are part of a mansion flat's value. We restore and replicate period detail rather than strip it out.
Mansion blocks are tightly managed. We prepare the drawings and specification for the Licence to Alter and work to the managing agent's surveyor and house rules.
Solid and timber floors between mansion flats must meet Building Regulations Part E acoustic standards and fire separation. We design compliant build-ups that also protect period ceilings below.
Original wiring, plumbing and heating are usually well past their life. We re-service the flat discreetly, routing M&E to preserve period fabric wherever possible.
Communal entrances, lifts, stairwells and porters mean access and protection must be planned carefully. We agree a logistics and protection plan with the building before we start.
Many mansion blocks sit in conservation areas or are listed. We manage the planning, conservation-area and Listed Building Consent issues alongside the freeholder consent.
Mansion flat programmes depend on size, the extent of restoration and re-servicing, and the building's own controls. The figures below are indicative on-site durations; a detailed programme and fixed quotation follow a survey.

We assess the flat, review your lease and the block's alteration rules, and identify the period features worth retaining — setting the consent and restoration strategy from the outset.
Our architects develop a scheme that respects the period character; we prepare the Licence to Alter and any planning or Listed Building Consent the building requires.
Our engineer designs any structural alterations; we detail Part E acoustic and fire separation that protects the flats around you, and obtain Building Regulations approval.
Our build team restores period fabric and re-services the flat, working to the block's access, hours and protection plan under a dedicated project manager.
We complete joinery, decoration and restoration, then hand over with certificates and our workmanship warranty.
