Looking to extend your home? At Clarke and Whalen Architects Limited we have completed a wide variety of extension projects in and across Hertfordshire and the surrounding counties over the past 40 years. Whilst the majority of our projects are local, within the central Hertfordshire region, including Harpenden, St Albans and Welwyn we are by no means constrained to these areas having worked across much of the county and other parts of the South East and beyond.

Getting to know our client’s requirements is a key factor to each project, and this, combined with our flexible professional services (to suit the needs of each and every client) is what has brought us success to date. We are able to help you with all stages of an extension project, whether it is a full or partial design service.

Clarke and Whalen Architects Limited can offer a full architectural service from concept to completion – see our services page [click here] for more information. Our design experience includes projects in sensitive locations, having completed works to many Locally Listed and Listed Buildings, we also have a broad knowledge of working on sites within Conservations Areas. Extension project costs for recent work has ranged between £50,000-£800,000.

Clarke and Whalen Architects Limited will be on hand to help guide you through the design and build process, to deliver a beautiful home environment that you can enjoy for years to come.
