How long does a London house renovation take?
Programme depends on design maturity, approvals, procurement, structural work, MEP, joinery and scope. A light refurbishment may be measured in months. A full townhouse renovation with structural works, extensions, basement works or bespoke joinery needs a much more detailed programme.
- Design and planning often take longer than clients expect.
- Joinery, stone, kitchens and specialist finishes need early procurement.
- A realistic programme avoids rushed decisions and expensive changes.
What is design and build, and why does it help?
Design and build brings architecture, interiors, technical coordination, construction, joinery and project management under one accountable team. For private clients, it reduces the gap between design intent, cost control and site delivery.
- One brief and one accountable team.
- Better cost feedback during design.
- Fewer gaps between consultants, contractor and client.
Do I need a party wall surveyor for a basement or extension?
Party wall matters are common for basements, chimney removals, structural works, excavations close to boundaries and many extensions. Notices may be required before work starts. Early advice is important because awards can affect programme and method.
- Do not leave party wall notices until the build start date.
- Coordinate structural drawings before notices where possible.
- Allow time for adjoining owner responses and surveyor appointments.
What does MEP mean in a prime London home?
MEP means mechanical, electrical and plumbing. In prime homes it includes heating, hot water, ventilation, cooling, electrics, lighting, controls, drainage, pumps, plant rooms, safety systems, testing and commissioning.
- Plan MEP before ceilings, joinery and finishes are fixed.
- Commission systems properly before handover.
- Keep records for maintenance and aftercare.
How do I renovate a listed building in Mayfair or Belgravia?
Listed buildings need a careful design and approvals strategy. The work must respect heritage fabric while delivering modern performance. Consent may be required for internal and external alterations, services routes, windows, structure and finishes.
- Start with heritage and planning constraints.
- Avoid assumptions about what can be removed or altered.
- Coordinate architecture, structure and MEP from day one.
What should I ask a luxury interior designer before starting?
Ask how the interior design will connect to architecture, budget, procurement, joinery, lighting, MEP and construction. A beautiful concept only works when it can be detailed, costed, procured and built properly.
- Confirm design stages and deliverables.
- Discuss budget before selecting finishes.
- Make sure joinery and lighting are designed early.
When should bespoke joinery be designed?
Bespoke joinery should be considered early, not at the end. Wardrobes, kitchens, media walls, panelling and storage affect electrics, lighting, ventilation, skirting, flooring and decoration.
- Design around how the room will be used.
- Coordinate sockets, lighting and ventilation.
- Allow realistic manufacture and installation lead times.
What is aftercare after a renovation?
Aftercare is the structured maintenance period after a project is complete. It can include MEP servicing, diagnostics, planned visits, reactive repairs, decorating touch-ups, minor upgrades, roof leaks, reporting and ongoing support for the home.
- Protects the investment after handover.
- Keeps systems maintained and recorded.
- Gives the client one trusted route for small works and repairs.
What should be checked before removing a chimney breast?
Chimney breast removal should be reviewed by a structural engineer and may involve party wall notices, building control approval, temporary works and careful sequencing. It should not be treated as simple demolition.
- Get structural calculations before works.
- Check whether adjoining chimney stacks are affected.
- Confirm party wall and building control requirements.
What is the best route for a Knightsbridge apartment refurbishment?
Knightsbridge apartment refurbishments often require building management approval, licence to alter, noise restrictions, access planning, lift protection, MEP coordination and premium finish control.
- Check the building rules before pricing.
- Plan deliveries, access and working hours.
- Coordinate MEP and interior design before strip-out.
What planning issues affect Holland Park renovations?
Holland Park projects can be affected by conservation areas, listed building settings, tree constraints, basement policy, neighbour impact and high expectations for design quality.
- Check conservation status and planning history.
- Review trees, basements and neighbour issues early.
- Use high-quality drawings and clear design justification.
Do I need building control for internal renovations?
Building control may be required where works affect structure, drainage, fire safety, insulation, ventilation, electrics, plumbing, staircases or change of layout. Internal works can still trigger compliance requirements.
- Check before removing walls or chimneys.
- Coordinate structural calculations where needed.
- Keep completion records for future sale and insurance.
How should a Mayfair townhouse renovation be planned?

- Understand heritage and access constraints.
- Plan MEP routes before detailed interiors.
- Build in procurement time for specialist finishes.
What should be included in a scope of works?
A proper scope of works should describe demolition, structure, drainage, MEP, walls, floors, ceilings, doors, ironmongery, kitchens, bathrooms, joinery, finishes, decoration, external works, testing, handover and exclusions.
- Use drawings and written specification together.
- Make provisional sums visible.
- Separate client supply and contractor supply items.

- Review listed building and conservation constraints.
- Understand access, scaffold and neighbour impact early.
- Agree specification before pricing the build.
How do I plan a Chelsea kitchen extension?

- Check conservation area and planning constraints.
- Design the kitchen and structure together.
- Plan glazing, drainage and lighting early.
What affects the cost of a full home refurbishment?
The cost of a full home refurbishment depends on how far the works go. Decoration-only works are very different from a full strip-out with structural works, MEP, bathrooms, kitchen, joinery, flooring, lighting and interior design. Use the NU Projects Build Cost Calculator for an early guide.
- Define what is staying and what is being replaced.
- Check whether structure, services and layouts are changing.
- Agree specification before comparing prices.
Should I start with an architect or a builder?

- Start with survey, brief and feasibility.
- Bring cost advice into the design stage early.
- Avoid separating design ambition from construction reality.
