Who we are...

We are the UK’s leading Master Developer having been specifically created 13 years ago to disrupt the established approach to the promotion and delivery of large scale residential led Strategic Sites. Now owned by the Wellcome Trust we are committed to delivering on our purpose, vision and values and achieving our strategic objectives.

What we do…

At the core of our business are the 14 Strategic Sites where we are currently bringing forward, either directly or in partnership, over 16,000 acres of land predominantly within 100 miles of London. As Master Developer, we take responsibility for obtaining planning and delivering the sustainable green, grey and community infrastructure to establish high quality places within which we market fully serviced land parcels to housebuilders.
