Construction Company
in Buckinghamshire
Clarks Construction Ltd is a leading construction company in Buckinghamshire. A third-generation, family-owned principal contractor based in St Albans, we deliver commercial, education, residential and heritage construction projects valued up to £10 million across Buckinghamshire and the Home Counties.
Your Trusted Construction Partner in Buckinghamshire
For over fifty years, Clarks Construction has delivered construction projects across Buckinghamshire - from classroom extensions at Swanbourne House School to commercial refurbishments in Aylesbury and new build residential developments in Stewkley. Our directly employed site management team and long-standing subcontractor network ensure consistent quality and programme delivery on every project.
We are a principal contractor - not a builder, not a subbie. That means we take full accountability for your project from pre-construction through to handover. Whether your project is a £1 million school extension or a £10 million mixed-use development, we bring the same commitment to quality, programme and budget.
We are CHAS Elite accredited, ISO 9001, ISO 14001 and ISO 45001 certified, and members of the Guild of Master Craftsmen. We work to CDM Regulations 2015 and maintain full safeguarding compliance on all education sector projects.
