Your Vision, Our Expertise
At HAA, we don’t just design buildings — we create spaces that reflect your goals, values, and way of life. From the first sketch to the final build, we’re here to guide, support, and deliver lasting architectural value.
We listen closely to truly understand your needs, and then bring insight, creativity, and technical precision to every stage of the project. Whether we’re helping shape a new home, an extension, or a bespoke development, we work collaboratively to make the process easier and more rewarding for you.
We take the time to understand what matters most to you — then challenge and refine the brief to ensure the best outcome, both creatively and practically.
We believe the best results come from working together. Our team is proactive and communicative, so you can feel confident and supported throughout the process.
Our architects are skilled in both concept and detail. We bring together inspired ideas with buildable, efficient solutions that stand the test of time. We design with care — balancing form, function, and environmental responsibility in every project.

Testimonials
“Highly recommended. They have helped us modernise a Victorian semi, from planning through builder selection to delivery. Jono and Natalia have been a delight to work with”.
Chris S,
Henley-on-Thames
“Through each stage, Jono, Jason and the team listened to what we wanted and were proactive in their approach. The design of the house is perfect, modern yet keeping some of the original features. What we loved about working with HAA was how helpful they were through the build. We decided to project manage ourselves, but were novices, and so we leant on Jono and the team at times. HAA came up trumps, recommending companies throughout and giving tips on how to approach any issues which arose”.
Sarah-Lynn S,
Beaconsfield
“Everyone that walks into our home is completely wowed by the interesting and thoughtful design features that make this house extraordinary, we have even had people knocking on the door to tell us how fabulous the house is and they can’t believe the transformation”.
Kate D,
Marlow
“Jono and Natalia (and the whole team) at HAA have done an outstanding job helping us design our major house extension. Their expertise also helped us identify the right Contractor which has ultimately brought our design to life. Couldn’t recommend enough”.
Ged F,
Chalfont St Peter
“We cannot recommend HAA – highly enough, they are totally professional and make your ideas/ dreams a reality – with the help of a great builder too !”
Emma W,
Bourne End
“Jono visited us at home and along with a comprehensive presentation about the steps to be taken to achieve our goal, was quick to grab his colouring pencils and sketch ideas as we spoke. We were not very clear about what we wanted (we really didn’t know) and as total novices had no idea about the approach we should take. Jono emailed us a staged plan and was very realistic about costing. We spent a long time getting the design right and Natalia was instrumental in helping us achieve this”.
Leanne B,
Marlow
We are curious and work holistically, creating a fertile environment for transformative ideas to flourish and come to life
