FAQ’S

Do I need permission for an extension in Winchester?

Do you provide a guarantee on your building work?

We provide written guarantees covering our workmanship and agreed materials. This applies to projects across Winchester and surrounding areas.

How do you handle building regulations and inspections?

Building regulations are managed in full by our team. We coordinate inspections, liaise with local authorities, and maintain compliance throughout the build. Homes in SO23 and SO22 follow strict standards, which we meet through structured workflows and clear documentation and timely reporting.

How long does a typical home renovation take?

Timeframes depend on scope, structure, and access. Smaller renovations may take weeks, while larger projects take months. Properties in SO23 or SO22 often need careful sequencing. We provide realistic schedules and regular updates so you can plan with certainty from project outset.
