Specialists In Home Extensions, Conversions & Major Renovations

GRW Construction is a well established, family-run construction company that primarily specialises in home extensions, conversions and major renovations. Built on a cornerstone of strong professional values and absolute attention to detail, we pride ourselves in delivering excellent solutions for our clients.

Our projects are typically centred around Hertfordshire, North London and the surrounding counties and we have carried out a variety of major extensions and other construction projects over many years, all of which have been the result of recommendations. This was epitomised in one particular small road where we carried out a range of projects concurrently from 2007 - 2011.

We offer several bespoke services, all designed to meet both the exacting requirements of the client and project alike. We are able to fully manage all communications between Architect, Planning Departments, Building Control and the Local Authority. We provide complete dedication from the point of inception through to project completion, working closely with our clients every step of the way.

What Our Clients Say

"Now that the works have been completed I just wanted to let you know how pleased Joanna and I are with the high standard of works carried out at our home in Tewin, and more recently, the same high quality of works and the dramatic difference it has had on my business premises in Welwyn Garden City.

During both projects you have been most helpful and offered practical solutions to problems that occurred during the project. Your supporting team obviously takes a pride in their work and are very thorough. Thank you for your efforts and be assured that I will not hesitate to recommend you and your team at every opportunity.

Kind regards and sincere best wishes."
