Projects in Higher Denham and Sandon Barn required bespoke engineering, including steel shutter boxes and raised drainage designs to prevent groundwater contamination.
At Aldenham’s 13th-century cottage, care was taken to protect existing structures while upgrading outdated systems.
Some sites (like Watford) required Environment Agency permits. Willowmead handled all paperwork and compliance verifications internally.
