Construction has commenced at Kielder Castle, signalling a major milestone in the transformation of this Grade II listed former hunting lodge into a dynamic, year-round multi-use visitor and community destination. Located deep within the Kielder Forest in Northumberland, the landmark project brings together heritage restoration with new-build intervention in one of the UK’s most remote rural contexts. 

We’re proud to share that planning permission has been granted for Beehive, a carefully developed rear extension to a Grade II listed home located in Dorking, Surrey.

Tucked away in the Berkshire countryside just outside Newbury, Virginia Lodge is a handsome early Victorian home set on a generous, split-level plot with an expansive garden.

With planning permission secured, construction is set to begin at Fulwell Farmhouse, a historic gem in the heart of the Cotswolds.

We are delighted to share that Mailen Design has received planning permission for a sensitive extension to a charming 19th-century cottage.

Our latest project, Fulwell Farmhouse, is a stunning example of Mailen Design’s commitment to preserving heritage and sustainability.

We are pleased to share that we recently received planning permission and listed building consent for a historical property in Oxfordshire.
