Frequently Asked Questions

Many conversions, particularly lofts and garages, fall under "Permitted Development" rights. This means you may not need full planning permission. However, rules vary by borough and property type (e.g., conservation areas). We assess your specific situation and handle all necessary applications.

While it varies by area, a high-quality loft or basement conversion can add significant value, often up to 20%, to your property. This makes it a smart financial investment in the London market.

Timelines depend on the complexity of the project. A typical garage conversion might take 3-4 weeks, while a loft or basement conversion usually ranges from 6-12 weeks. We provide a detailed schedule before work begins to ensure minimal disruption.

We operate throughout Greater London and the surrounding areas. Our team is experienced in working with the diverse housing stock found across the capital.
