Castle View Retirement Home, Windsor


Client:  Castleoak Group Ltd/Castle Retirement Living Ltd

Sector:     Health/Care Homes

Value:      £20m

Cambria Consulting were the appointed Civil, Structural and Environmental Engineers on this 3/4 storey luxury development located in the centre of Windsor with direct views to the castle. The project delivered 58 retirement apartments each with their own external dual aspect balconies, undercroft car parking together with a completely self-contained Extra Care Facility. With a construction value of £20m the development provides roof top conservatory and gardens and on-site Red Cross and Mencap facilities.


The structure solution adopts a concrete frame with flat slabs for ease of services distribution and fin columns so they are hidden within wall thicknesses. The basement car park utilizes contiguous concrete piling founded within the lower London Clay strata and deals with the challenging ground conditions which are prevalent in the area with a high water table, permeable strata and risk of running sand. The concrete framed solution is also ideal for delivering the required waterproofing details resulting from the roof top gardens and plant areas.

Generally, the site was a straight forward build out but as with most sites it did have its own particular challenge in the 600mm diameter adopted foul sewer which crosses the site at approximately 3m deep. This Thames Water asset was diverted off the site via a section 185 Agreement with the works completed ahead of the main construction programme.
