Mansion Block Refurbishment London
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.
Refurbishing a Period Mansion Flat
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.
Period Character, Restored
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.
Freeholder & Managing-Agent Approvals
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.
Acoustic & Fire Separation
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.
Services Brought Up to Standard
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.
Protected-Building Logistics
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.
Conservation & Listing
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 Block Refurbishment FAQs
Plan the apartment and common parts together
A mansion-flat brief should describe the home and the route used to deliver the work. Record the building's requirements before confirming installation methods, delivery sizes and the construction programme.
Document access
Measure or verify the entrance, staircase, lift and delivery route. Request booking arrangements, permitted working hours, protection requirements and the process for arranging interruptions to shared services.
Coordinate the proposed work
Ask the appointed team to identify shared structure, service routes and fire or acoustic interfaces affected by the design. Keep responsibility for the required surveys, submissions and inspections explicit.
Agree restoration and handover
Record the starting condition of common parts, the agreed protection and the completion inspection. Track the required records, snagging and reinstatement obligations alongside the apartment handover.
