An Extra Care Scheme or Extra Care Housing is also known as very sheltered housing, assisted living, or simply as ‘housing with care’.
The brief for the Waverley Care Homes and Gardens was to add an extension to an existing 66 unit extra care home to add an additional 62 self-contained apartments. The existing building was timber framed and the ground conditions were challenging in that there was an existing basement under the proposed footprint which needed filling and significant made ground, overlaying high volume change potential clay.
The site had previously been landscaped, so the foundation depth ranged from 2.5m deep to 1.4m with numerous steps and level changes. We modelled the foundations and shared with the surveyor so they could understand the complications within the ground. Because we’d made an assessment of the foundations well before we got to site we’d identified potential issues early on in the project and completed a virtual exercise to identify whether we could use existing levels or cut and fill. This gave the project surveyors options to price to ensure the best value was offered.
The brief included a semi-basement to make use of natural topography of the ground. We were tasked with looking at the structural implications of using the semi-basement to house the water tanks with consideration of the weight of them and made simple modifications to enable this to happen.
