Lyon Square is located around a triangular site in the middle of Harrow town centre. CZWG was approached by Redrow Homes to make significant design changes to an existing planning permission, all to be agreed as minor amendments within a very tight programme. The brief was to provide better quality housing which would include full compliance with the current GLA’s Housing Design Guide and meet Lifetime Homes requirements. The design amendments included increasing the floor to ceiling heights of the consented development drawings by 300mm to meet the GLA specification. This resulted in an increase in height to some of the lower buildings, and the loss of floors from the tallest five buildings; those flats removed were relocated so that the total number of residential homes did not alter. CZWG successfully delivered the design changes through negotiations with London Borough of Harrow within an eight-week period, culminating in a revised planning submission dealt with under a section 73 application.
