People guide us

Architecture does not exist in a vacuum – it must meet the needs of the people who commission and use it. Our depth of experience has taught us the value of genuine engagement. We work closely with each client to understand their particular needs, before devising imaginative solutions that expand on possibilities while meeting constraints.

Place inspires us

As architects, we strive to create spaces of lasting joy and fulfillment. Our purpose is to design buildings that inspire people through light and form while offering a high level of comfort and usability. Lines of sight, proportion, balance, material wisdom and environmental compatibility are all elemental to the places we create.

Our studio

For a highly successful architectural firm, our studio is surprisingly low-key. We have purposefully maintained a small team so that we can remain focused on our clients and projects. Our multi-talented staff are led by three directors, each of whom bring their unique style of design and leadership to the table.
