Renovating a new-build flat in LondonAI Visualiser — before-and-after renders
Mock up a new-build flat refurbishment on your own London room photo before you brief a contractor. Average refurbishment costs in London for this property type sit between £16,800 and £56,000 — visualise it for £2.99 first.
Typical new-build flat layout
Open-plan main living area, narrow corridor to bedrooms, fitted bathroom and en-suite, juliet balcony or terrace. Storage is consistently the weak point. Most renovation work is therefore cosmetic restyling plus storage joinery rather than structural change.
New-build flat renovations are mostly about installing fitted joinery, replacing developer-grade kitchen doors and worktops, and upgrading lighting to add character without breaching the lease.

Common renovation pain points for a new-build flat
Issues that catch out first-time renovators of this property type — particularly relevant in London where Greater London contractor lead times are typically 6–12 weeks.
- Bland developer-grade kitchens and bathrooms feel mass-produced
- Lack of storage — coats, hoover, suitcases all compete for a single utility cupboard
- Acoustic transfer between flats can be poor if developer specification was minimum
- Restrictive lease covenants on flooring, painting and structural alterations
- Service charges often include sinking-fund contributions for future external works

Planning permission notes for London
In London and the wider Greater London area, many boroughs operate Article 4 Directions that remove permitted development rights for window changes, render alterations and small extensions. Conservation areas — particularly inner-London boroughs like Camden, Islington, Hackney, Westminster, Kensington and Chelsea — require formal planning consent for visible alterations. Always check the borough planning portal before stripping render or replacing sash windows.
Flats almost never have permitted development rights — every meaningful change needs landlord/freeholder consent under the lease. The lease will dictate what flooring underlay, what window treatments and what bathroom waste runs are permitted. Always read the lease before commissioning works.
Watch-outs your surveyor will mention
- Cladding fire-safety certification (EWS1) is critical post-Grenfell — buyers and lenders insist
- Cracking in plasterboard joints is normal as new buildings settle in their first 5 years
- Underfloor heating manifolds and pump should be serviced annually
- Mechanical ventilation with heat recovery (MVHR) filters need 6-monthly cleaning
