Decorating a mansion flat

Identify the block’s architectural character

Westminster’s Dorset Square audit identifies the mansion blocks of Clarence Gate; its East Marylebone audit describes later Victorian and Edwardian red-brick blocks with timber sashes and decorative brick or stonework. Those settings differ from a flat formed within a Georgian terrace. Use the relevant audit to understand the building, then inspect what survives at your own windows, entrance and internal junctions before proposing a treatment.

Draw the boundary of the proposed work

Make a separate marked photograph for the flat entrance and for each window, showing which faces are included. Ask the managing agent to identify any shared responsibility, existing finish specification or lease restriction affecting them. Treat a balcony, communal landing or external face as a distinct enquiry. Resolve these boundaries before a room colour is extended onto an element that belongs to the wider building’s scheme.

Survey the shared route with the manager

Walk the delivery route from the pavement to the flat with the person responsible for common parts. Note the vulnerable corners, threshold changes and any restrictions on lift use. Agree how protection will be secured and removed, where deliveries can be received and who checks the route at the end of a working visit. Inside the flat, nominate a materials position that keeps the entrance and circulation available.

Separate decorative defects from unresolved repairs

On each room’s photographs, distinguish paper seams and worn finishes from areas with water staining, loose material or recurring cracks. Ask for those uncertain areas to be assessed before the decorative allowance is settled. If the cause or repair falls outside the flat, identify who will resolve it and how completion will be confirmed. Decoration can then follow a defined repair, rather than becoming the point at which an unresolved building problem is concealed.

Use the hall to test the room sequence

Start the programme sketch with the spaces reached through the hall and the doors that must remain usable. Allocate a place for furniture from the first room before selecting the next one. Discuss when painted doors can be handled and how the chosen products affect ventilation and reoccupation. Where the flat remains in use, agree the daily handover of circulation and essential rooms as part of the working arrangements.

Leave a record the next maintenance visit can use

Prepare a finish record by location, including the manufacturer’s colour reference, product and sheen for each wall and timber element. Distinguish the flat’s scheme from any manager-approved treatment at the entrance or windows. Add instructions for retaining spare material and the relevant product care information. This gives a future repairer a specific starting point, even when the visible colour varies with the light across the room.
