This guide focuses on the decisions that determine a St John's Wood flat refurbishment: defining the work, checking property and consent constraints, setting an evidence-backed budget and planning the sequence. The detailed local service scope remains on the St John's Wood flat refurbishment page.
Start with the local service context
St John's Wood sits in the City of Westminster, and a large share of its homes are leasehold flats — within substantial detached stucco villas and grand mansion blocks. Refurbishing one is a full interior project: reconfiguring the layout, renewing services and finishes, and often combining or reworking rooms within the existing footprint.
Do I need my freeholder's permission to refurbish a St John's Wood flat?
Expect the lease to lead the project. Leasehold tenure covers nearly every mansion-block flat in NW8 and a good share of the grandest villas, which seats the freeholder, the managing agent and the lease terms at the table with Westminster from day one — and no change to services or layouts should begin before freeholder consent and a Licence to Alter are secured.
What are the St John's Wood mansion blocks like to refurbish?
Demanding in the right ways. The imposing red-brick blocks that stand alongside the villas of Hamilton Terrace, Carlton Hill, Grove End Road and Elm Tree Road hold lateral flats, and refurbishing one is a Licence to Alter project in which acoustic separation, services routing and managing-agent coordination sit at the core of the scope rather than at its edges.
Define the work before comparing prices
Record the existing layout and services, then separate essential fabric and compliance work from layout changes, fitted joinery and finishes. For a leasehold flat, place freeholder, managing-agent and Licence-to-Alter requirements on the decision list before design is fixed.
Check the recorded local constraints
These cited records identify issues to verify for a St John's Wood brief. They do not replace property-specific advice or a current consent check.

Use the approved budget ranges consistently
The approved flat range is based on a full two-bedroom refurbishment. Keep that basis visible when comparing it with a project-specific scope.
| Scope basis | Guide rate | Typical total | Programme |
|---|---|---|---|
| Full two-bedroom flat refurbishment | £900–£1,700/sqm | £60,000–£110,000 | 16–32 weeks |
These are planning ranges, not a quotation. The property survey, final scope, specification, access and consent requirements determine the project-specific cost and programme.
Build the brief in a practical order
- Confirm the measured area, retained rooms and every proposed structural or services change.
- Check the lease, freeholder and managing-agent requirements before committing to a layout.
- Confirm whether planning permission, listed-building consent or building-control approval applies.
- Price one written scope so exclusions, provisional sums and finish allowances can be compared.
- Plan access, deliveries, working hours and neighbour communication for the specific building.
