Frequently asked questions
Do you charge for estimates?
No. Consultations and written estimates are free and carry no obligation. For complex structural projects that need engineering or design work before a price is possible, we will explain any professional fees clearly before anything is commissioned.
Do I need planning permission for a loft conversion or extension?
Many loft conversions and single-storey extensions fall under permitted-development rights, but conservation areas, flats, maisonettes and larger designs usually require a full planning application.
We review your property's position at the start and handle the process — architectural drawings, submissions and liaison with local councils across London and the Home Counties.
What is the typical timeline for a full residential renovation?
Timelines vary with scope, but for a full-scale, high-end renovation clients should anticipate:
- Pre-construction (8–12 weeks): design, structural engineering and planning.
- Primary works (16–24 weeks): structural alterations, first-fix services and shell completion.
- Finishing phase (8–12 weeks): joinery, specialist finishes and commissioning.
Smaller projects move much faster — a bathroom typically takes 2–3 weeks on site and a kitchen 3–5 weeks.
How do you handle budgets and payments?
Estimates are broken down by stage so you can see where every pound goes. Once scope is agreed, payments are staged against progress on site — you pay for work as it is completed, not large sums up front. We recommend holding a 10% contingency for the unforeseen issues that are common in older UK properties, and we bring you costs and options before any variation proceeds.
