Case Study – Ecclesbourne Reach

Duffield, Derbyshire


Ecclesbourne Reach is a residential development in Duffield, Derbyshire comprising four detached individually designed prestigious houses. The site was formerly the home of the Derby Colour Works factory and sits alongside the River Ecclesbourne in a rural setting. The properties are traditionally built using loadbearing masonry walls with a coursed stone outer face. The roof structures are traditionally designed with large clear open spans to facilitate further accommodation.

Given the sites proximity to the River Ecclesbourne we worked closely with the client Redmill Industries, Montague Architects and Gisborne Homes to ensure that all works impacting the River were fully approved by the Environment Agency.
