The company was established in 2006 by its director Mark Sheehan who has over 30 years experience in the design and construction of buildings.

We undertake work on a large variety of products from small rural house extensions through to Penthouse Apartments in Inner London . We appreciate that each project is unique to our client and consequently they all receive the same degree of personal attention that National Companies may not be able to deliver

Mark worked for prominent Norwich based Architects - Feilden & Mawson before spending more than 20 years working in Building Control for Local Authorities in Norfolk & Gloucestershire. Mark Sheehan Building Consultancy Ltd draws on this substantial experience in Architecture and Building Control.

Mark is a Fellow member of the Chartered Association of Building Engineers, a body recognised throughout the United Kingdom and Europe for Architects & Surveyors.

The company has offices in Swansea and Chalford . We are ideally located for all work throughout South Wales, Gloucestershire, the South West, and the M4 corridor from Swansea to London. SAP calculations and Consultancy work can be undertaken throughout the country.

We are a small family company and pride ourselves in the quality of service we provide. You will be provided with a fixed price quote for any projects you submit to us and can be assured there will be no hidden extras.

We provide PDF copies of all our work as standard practice which can be e-mailed to you to minimize delays but will always provide hard copies if requested.
