Contact ConsultantWhile many loft conversions fall under 'Permitted Development' (PD) rights, luxury conversions—especially those involving structural alterations or in Conservation Areas—often require full Planning Permission.
One Call UK handles the entire submission process, including architectural drawings and liaison with local councils across London and the Home Counties.
Timelines vary by scope, but for a high-end full-scale 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): High-end joinery, specialist finishes, and commissioning.
We operate on a transparent 'Fixed-Price Contract' model once the technical design is frozen. Our quantity surveyors provide a detailed breakdown of every unit cost, from structural steel to the final coat of heritage paint. We also recommend a 10% contingency fund for unforeseen structural issues common in historic UK properties.
All One Call UK projects are backed by a comprehensive 10-year structural warranty. We carry £10m in Public and Employer's Liability Insurance, as well as Professional Indemnity insurance for all design and engineering works performed in-house. We also provide bespoke insurance solutions for 'Homeowner Remaining in Residence' scenarios.
