Postlethwaite Hill Architects is a RIBA chartered practice based in Norfolk. Having worked at leading London studios including Foster + Partners, Assael Architecture and Hugh Broughton Architects, directors Laura and Adam now bring that experience to local projects, combining design ambition with a personal, hands-on approach. Our aim is simple: to deliver thoughtful, well-crafted buildings that serve their users and enrich their setting.
Thoughtful design for people and places
Flexible Services, Focused Design
Every project is different and so is the way we work. Whether you're planning an extension, fit-out, new-build home, or a larger development, we shape our services around your needs, your site, and your ambitions. We understand that some clients want end-to-end support, while others may only need help with a specific stage, such as securing planning permission or producing technical drawings. Our aim is to make the process clear and manageable, providing the right level of input at the right time.
Personal, Professional & Hands-on
We’re a small architectural practice with a simple approach: every project is led by the same experienced architect from start to finish. That means no handovers, no confusion - just clear communication, consistent thinking, and a close working relationship from day one. Our size is our strength. It allows us to be responsive, collaborative, and fully invested in each brief. Whether your project is straightforward or complex, we bring care, attention to detail, and a deep commitment to quality at every stage.

Jamie Cook, Business Owner
“Adam was essential in helping us get this challenging project off the ground. He provided invaluable advice at the start of the project and continued to be communicative and proactive throughout the process. He was prompt with his delivery of information and always took the time to explain complex issues to us in a clear way”

Helen, Home Owner
“Adam and Laura helped me consider how I could rework my home to make better use of the space I had. I love my garden, and their proposal really demonstrated how I could better connect the rooms at the back of the house to the outside. They were prompt in their communication and responded well to my comments on their designs.”

K & G, Home Owners
“PHA convinced us that we didn’t have to build an extension to get much more from our home. Their clever idea to convert the garage instead of building a new extension has given us a lot more confidence to go ahead with the build in the knowledge that it will cause less disruption to our lives. We’re really excited to move on to the planning stage and have recommended Adam and Laura to our friends.”

“We’ve absolutely loved working with Postlethwaite Hill Architects on the design for our extension in Hove. The team were so thoughtful taking the time to understand how we live and our vision for our home - and helping us navigate all the different options and stages in the process, which was so appreciated as first time renovators (no question was too stupid!) They've created a layout we love and they were patient and collaborative throughout. Highly recommend!"
