In September 2025, JP Building Ltd officially rebranded to Tier One Developments Ltd. While our name has changed, our commitment to delivering high quality projects and exceptional service remains the same.

Just the name. The same team, led by Managing Director Joseph Polfrey, continues to deliver extensions, renovations, new builds and planning across Cambridgeshire, Bedfordshire and Milton Keynes from our base at Wyboston Lakes near St Neots.

Repeat clients mean everything to us. Some of our current projects are for homeowners we first worked with as JP Building, including a family whose extension we completed back in 2016.
