Average rating: 5 out of 5 stars17 May 2026
“Nesh made the planning stage of our extension and renovation rapid and stress-free; he's extremely knowledgeable, responsive and has been an absolute pleasure to work with from start to finish. Planning permission went through with no issues and we've been given lots of reliable contacts for the next stage of the process. Would 100% recommend to anyone looking for an architect!”

“I am able, with pleasure, to say that Annie is an absolute joy to collaborate with. She listened carefully to the overall look I wanted to achieve, ably helping me to achieve it, whilst at the same time expanding my horizons. This was a very large, whole house project. Annie provided constant support, advice and monitoring of progress whilst allowing me personal choice of all aspects of the design. She introduced me to new, stylish and unusual furniture, lighting and soft furnishing sources. Thank you, Annie, I am delighted with my new home.”

“Fran worked with us during lockdown to design our extension and then led on the approvals process with Cardiff Council as this is a grade II listed property. This was a complex process but Fran navigated us through it with expertise. Fran was endlessly patient with us as we explored different options, producing numerous designs and drawings. Once we started the work, Fran acted as project manager, liaising with the builders, and led on the many interactions with utilities companies as we had to redirect gas and electricity and have a new stop tap installed by Welsh Water. Fran was a steady, calm presence across all the dramas of construction and ensured that we stayed on track, to time and, more importantly, to budget. I'd definitely work with Fran again - she's creative, pragmatic, experienced and a great communicator. She's also a lovely person who deeply cares about the quality of her work. We are really delighted with the work.”

Design and Build Company FAQs
In short, a design and build company consists of all stages of the construction process, from design to build, in one place. A design-build firm works under one contract with the project owner to complete both design and build steps of the project.

They will take on the responsibility of planning the project, drawing up the designs, costing, sourcing the building materials and supplies, building the structure, installing any permanent features and possibly advising on the interior design of your home; all while consulting you every step of the way.
Speed and cost. Hiring a design & build company for your Ystrad Mynach project means that the whole process from start to finish will be quicker, as all stages of the project will be handled by one company. This also saves time finding additional companies to complete certain stages of the project and potential back & forth between builders and designers to discuss the plans.

By using a design and build company in Ystrad Mynach for your project, you will also be given an all-in-one quote for the design and construction of your project. This is often cheaper than hiring separate professionals for each step of your project.
