The Placemakers who

From our Part I year out students to our Directors, our entire team at KSA are Placemakers. Working closely together provides the broad expertise, and creates the unique culture, which are key to designing and developing places that people will love living in.

Our Placemakers

Making places. Why does it matter so much?

As our society evolves, the pressures of population growth, immigration, resources, environmental concern and physical and mental wellbeing bring the issue of housing into ever sharper focus. As residential architects, we believe passionately that providing well-planned and constructed housing, in thoughtfully designed neighbourhoods, is a fundamental duty of society. we are proud to play our part in helping to fulfil this duty.
