Social Housing

Project: Kingston Crescent, Portsmouth

Client: Portsmouth Housing Association

Architect: Kenn Scaddan Associates Architects

Principal contractor: Drew Smith

Timber frame contractor: Prestoplan

Contract value: £2.5m

This project for Portsmouth Housing Association included social and shared ownership properties as well as some ground floor special needs apartments.  Our involvement in the project started at the initial structural appraisal through the detailed design stage and included regular site inspections until project completion.  The structure consisted of a total of 26 units in a 3/5 storey block.  The foundations were deep mass fill trenches as this solution was found to be more economic than piled foundations due to complex ground conditions across the site.  One area of the foundations was cantilevered so as to not undermine the adjacent structures.  The ground floor construction was brick and block supporting an “omnia” reinforced concrete transfer slab.  This then allowed the 2/4 storey timber frame load bearing walls to be offset from the ground floor structure.  We also provided external works, drainage design and construction information including assistance in avoiding the extensive services within Kingston Crescent and Gamble Road.  We also prepared the timber frame design calculations including the necessary disproportionate collapse considerations, directly for Prestoplan.

Prestoplan were introduced to Cowan Consultancy at an early stage of the design development and subsequently appointed them to provide a timber frame structural design, including consideration for disproportionate collapse.  Our expectations were met and we experienced a thorough service that highlighted the best solutions, including onsite support when required.
