How a scheme runs with us

Who we work with

  • Landowners

    You have a plot or a field that is doing nothing. We look at what it can take and can deliver it as finished homes, without you managing a single contractor.

  • Housing associations and councils

    An accredited partner already trusted on social housing estates in the Valleys, from retaining walls to new homes.

  • Investors and partners

    A delivery team that prices the ground because it digs the ground, so the biggest unknown on a Valleys site is handled first.

Valleys sites are won or lost in the ground.

Steep plots, old retaining walls and wet ground are where schemes in the Valleys tend to run over time and budget. It is also where our team has spent its working life. As approved Platipus installers we can often stabilise a failing wall instead of rebuilding it, an approach Tai Calon says saved them tens of thousands of pounds.

  • More than 50 years combined experience below ground
  • Approved Platipus earth anchoring installers
  • CHAS accredited, with CSCS, CPCS and Street Works certification
