Common Questions, Answered
Build the budget from the actual design, structure, ground/access conditions, services, specification, professional and statutory costs, VAT, allowances and exclusions. The current TCM register does not approve a universal London per-square-metre or total extension price for this hub; use the dedicated cost guide and a project-specific quotation.
It depends on the property and proposed roof alteration. Some loft projects can use permitted-development rights when every applicable condition and limitation is met, while others require a planning application or another route. Check the exact property, planning history, designations and design in the dedicated planning guide.
There is no universal build duration. The programme depends on design information, permissions, procurement, ground and structural conditions, access, inspections, long-lead products, services, finishes and approved changes. Use the project-specific programme and the dedicated timeline guide rather than a fixed number of weeks.
It can affect market value, but the result depends on the property, design, usable space, quality, location and market conditions. This hub does not publish a percentage uplift or return-on-cost promise; use independent valuation evidence for the actual property.
