Castle Builders is family run, has expertise in every area of construction, and specialises in hi-spec extensions, new builds, renovations and loft conversions.

​Our standards are high and we achieve superior results because we work with exceptionally trained and experienced local craftsmen. We collaborate throughout the construction process to provide innovative, efficient and contemporary builds throughout St Albans.

Since our inception, our goal has been to provide our clients with open and honest collaboration throughout the construction process. This has resulted in long-term relationships with our clients, who often refer us to their friends and acquaintances, creating a powerful word of mouth network.
