Established in 1995, we’re proud that Harries Planning Design Management has grown with our clients to become the trusted building design team we are today.

We provide a complete building design and project management service taking projects from conception, through design and planning to the delivery of beautifully-designed buildings, new extensions and sympathetic renovations. We manage construction activities with the same level of enthusiasm and determination, providing hands on project management services to bring your buildings, extensions and renovation projects to life.

Understanding your business means we can deliver the buildings you need
We are very proud of the relationships we have built through our work over the years. Much of our business is ‘repeat business’ from clients who have used us once and then come back again and again to work with us on subsequent projects. This is good for our business but also for our clients. By building up longstanding relationships and understanding out clients’ aims – be they business aims or personal, we can work more closely with them on projects, and advocate more effectively for them during the planning process.  We also receive a huge amount of work by ‘word of mouth’ recommendation – a huge testament to our reputation, and something we are very proud of.

From our purpose-built office in the Pembrokeshire Coast National Park, built using renewable and sustainable materials, we work for individuals and commercial clients. We cover a wide range of sectors, working not only in Pembrokeshire, Ceredigion and across Wales but all over the UK. Not only do we work on residential, commercial, industrial, rural, and ecclesiastical building projects on a regular basis, we deal with specialist areas such as waste and energy developments and listed buildings.

Delivering design to meet your aspirations and planning requirements
Underpinning much of what we do is a careful understanding of the planning regimes in operation in the areas where we work. We take care to deliver designs that will meet our clients’ needs and aspirations and satisfy planning requirements. We also understand that buildings, whether new builds or renovations, commercial buildings or residential extensions – must deliver financially. We balance all our designs with budgetary control, statutory compliance and functionality to ensure that the resulting buildings and structures work for our clients both practically and financially.
