Architecture That Makes a Difference

At OHA, we understand that a fantastic end result begins with a considered and passionate start.

Every project is a chance to create something meaningful, architecture that enhances everyday lives, celebrates its surroundings, and makes a lasting contribution to both people and place.

We draw inspiration from the landscape, the built context, and the layers of history that shape each site. The result? Sustainable, modern architecture that is deeply rooted in its setting and designed to stand the test of time.

Our aim is to make a confident, thoughtful statement, one that reflects a building’s unique moment in time, its location, and its purpose.

We believe passionately in the positive impact that well-conceived architecture can have , not just on the immediate users, but on the environment, the community, and future generations.

Tailored Services. Trusted Results.

We work across a wide range of sectors , from private homes and housing developments to education, leisure and community buildings, always tailoring our service to suit the people and purpose behind each project.

Our talented, growing team has experience in projects of all scales, from modest extensions to large, multi-stakeholder public sector schemes. Whether you’re a homeowner or a developer, a college or a care provider, you’ll find we bring the same level of care, creativity and commitment to every brief.

Many of our clients return to us time and again, from local authorities and landowners to families and forward-thinking developers who share our values of raising design and sustainability standards in 21st-century building.

We offer:

• Feasibility studies

Over the past decade, we’ve also built a trusted network of consultants, craftspeople and specialist teams, allowing us to assemble the right expertise around your project, at just the right time.

No matter the scale or challenge, every project is an exciting one for us, and we’d love to help you realise yours.
