Dennis Hellyar - About

Dennis Hellyar Architects is an RIBA Chartered Practice providing Architectural Services in South Wales and South West Regions - Our City focus is on Swansea, Cardiff, Bristol & Bath.        

Working formerly with Cardiff based Architect practices in the past and delivering high quality projects in the Commercial, Education and Residential Sectors in the South Wales and South West regions, Dennis Hellyar established dhA to serve primarily two key needs:


- Domestic Residential clients with a desire for sustainable, high quality design, needing a creative professional and experienced architect for domestic and residential projects of any size or nature.


- Commercial clients seeking a smart, personalised and bespoke design office, delivering high end, contemporary, ecologically green and sustainable design, with care and sensitivity for the character of the local architecture and surrounding environment.   


Dennis Hellyar works closely with all projects in the office and given the broad experience from larger practices and the employment of State of the Art BIM Virtual Building Modelling as standard, dhA has the knowledge, technology, skills and enthusiasm to provide Architectural Services for all clients.


At dhA, we are flexible and adaptable when it comes to delivering architectural services across the domestic and commercial sectors. All of our projects are unique and we work closely with the client to discuss exactly what is expected, throughout the project.


Please take some time to look at the past Architectural projects which Dennis has worked on in Cardiff and Wales. If they are of interest, we welcome the opportunity to meet people to discuss their aspirations, so please feel free to get in touch with us today. Call us on 01446 500720 or email for more information.

Testimonial - Client for St. Cynog: Nigel Gabriel, January 2016


'I cannot recommend Dennis Hellyar architects highly enough. This was a bereft and unloved property in poor condition in need of considerable attention. DHA reviewed, and saw potential with an imaginative, bold scheme (perhaps too bold for some). Their enthusiasm and imagination carried all before it, and now we are the proud owners of an exciting and remarkable space at the heart of the city. 

Being new to renovations, we were heavily reliant on the team put together by DHA and I now believe our confidence in them was well placed. DHA was the fulcrum of the team, keeping a weather eye on progress, quality and costs. Above all their attention to detail proved the key to a quality result. 

The firm has an enormous wealth of experience covering domestic and commercial work and it was evident this was brought to bear in the job. In particular, DHA went the extra mile to make this work'
