The BALI Awards adjudication panel highlighted the sheer scale of the project, from the initial major earthworks and installation of attenuation draining to the outstanding hard paving and construction of multiple walls and terraces.
"Stunning" planting schemes in a series of garden rooms had, said the judges, also benefitted from the "expert horticultural hands of the contractor", making it a worthy recipient of the Grand Award.
Commenting on the company’s achievement, outgoing chair of the adjudication panel Greg Allen said:
"It is wonderful to see a private garden scheme winning the Grand Award. The complexity and challenges of this project belie what is a simply beautiful and tranquil space."
"Designed to create a series of garden rooms, each with their own ambience and interest, this scheme is proof that however good a design may be it relies entirely for its truthful implementation on the skill and expertise of the contractor."
"Bowles & Wyer has demonstrated its professional excellence across the board and the judges’ decision to recognise the company’s achievements was unanimous."
