• Conversion of existing buildings
• Self-build project
Phosphates mitigation

Planning drawings of original bungalow for demolition at Willen Farm

Following Pre-Application discussions, the Council confirmed that our approach to the site would be supported provided the design were acceptable and any adverse impacts were overcome. We worked closely with Orme Architecture to devise a scheme that was both appropriate to the site and that provided the special accommodation required by the applicant and his family.

The proposal included the conversion of an existing cowshed which formed part of the dwelling attached to a very generous 2 storey main house. Extensive landscaping restores the farmyard and traditional orchard.

As the site is within the Somerset Levels and Moors Catchment Area and cannot connect to mains drainage, it was necessary to come up with a strategy to mitigate phosphate arisings. A ground-breaking phosphates strategy which uses a willow bed and high performing package treatment plant was devised by Zak Simmonds of Enviren and was agreed by Natural England.
