The project comprised of the construction of a new 115 unit retirement village in a 10 hectare landscaped site in Southampton.

A major engineering consideration for the project was the adaptation of the Grade 1 listed Elizabethan Manor House undertaken in-line with English Heritage requirements.

Due to the site topography, foundation solutions comprised of elements of strip, ground bearing and mini-piled type.

SuDS techniques were used to dispose of surface water on site, and these comprised of a mixture of conventional soakaway devices, infiltration trenches and permeable paving. Foul flows were disposed to a new sewage treatment plant and land drainage fields to Environment Agency requirements.
