Our history.

KSA began life in 1984 as a partnership between former Portsmouth City Council and Hampshire County Council architect Kenn Scaddan and his erstwhile PCC colleague John Wilson.

By the time Kenn stepped aside thirty years later, KSA had established its reputation as one of the South Coast’s leading independent practices, with an ethos of ‘creating places’ - developing homes and residential estates, as well as commercial, third sector and civic amenities around the needs and wellbeing of the people who would occupy them.

Four decades of making ‘places for people’.

Our first project, back in 1984, was a commission to design the special needs Horizon Centre at Cosham.

In the 40 years since, we have built a reputation for delivering high quality, cost effective, affordable housing for housing associations and local authorities across the country, while maintaining our interest in other civic and third sector requirements.

Our focus, now as in 1984, is always on ‘Placemaking’.
