Smart House Extension
Architects in Cardiff
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!”

“We were very lucky to have been referred to Tom and Phil by our friends and I am so grateful for all the hard work they have done for us. From the initial visit to finishing the project, we couldn't have asked for a better team. What sets Tom and Phil apart from other architects is the transparency - fees, hours, expectations, budget vs actual costs, steps and process. At the beginning, like many others, we didn't know where to even start - we had a budget and we wanted a kitchen extension but we felt so overwhelmed. Tom and Phil took us through everything, it's been two years of hard work: nailing the designs, ensuring everything in place, obtaining approvals, finding an excellent builder, not compromising on quality materials and more importantly being excellent at finding solutions in those moments when you just want to give up and cry! Initially we definitely underestimated the importance of having a good architect and only now we understand how much cost it saved us and what good finish we achieved by having Phil and Tom from start to finish. For our next project we have already lined them up and wouldn't trust anyone else. We can't shout loud enough to anyone we know how amazing, professional and creative they are.”

Architect or Architectural Designer FAQs
An architect is a professional who designs and creates building plans, ensuring the building is functional, safe, and aesthetically pleasing. They collaborate with clients to understand their needs and create designs that meet their requirements. Architects also consider building codes, regulations, and sustainability principles in their designs. They may oversee the construction process to ensure it aligns with the design intent.
If you are looking at a house extension or building a new home from scratch, chances are you are going to need the help of a residential architect. They have extensive knowledge of architectural design, construction methods and building materials, not to mention a strong appreciation of ergonomics – warmth, light and flow within a property. Architects will also be far more capable of seeing the bigger picture – carefully balancing aesthetic appeal with structural safety. With their local knowledge, your Cardiff architect will also often help to obtain planning permission and building regulations approval.

    After choosing a residential architect, you will usually start with a consultation to discuss the project. Preferably at your property or building site where the work will be done. Give as clear a picture as possible of the kind of home you are trying to create to your architects. Chat through your goals, projected budget, scope of work, schedule and feedback, together with any very specific requirements you might have. They will explain their process to you alongside any other on-site visits up to and including the build stage, depending on whether they will be involved at that stage. From there they will produce the designs and plans required for your project.
    The cost of hiring an architect in Cardiff can vary depending on the scope and complexity of the project, experience, reputation, and location. Architectural fees are typically structured as a percentage of the project’s total construction cost, ranging from 8% to 15%. For example, if a project has a construction cost of £500,000 and the architect’s fee is 10%, the fee would be £50,000. It’s advisable to discuss fees and payment structures with architects in Cardiff during initial consultations.
