What qualifications and experience do you have as an extension builder in Petersfield?

An extension builder in Petersfield should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

What experience do you have with similar extensions in Petersfield?
