First things first
Got a plot of land that needs developing?
Send us the details or give us a call. We will talk it through with you, then meet you on site to walk the land together and give you a straight answer on what it can take.
-
2Prepare the site
Clearing the land, setting the levels and digging in the drainage the homes will need.
-
3Lay the foundations
Reinforced concrete foundations, services and roads, laid ready for the build.
-
4Build
The homes go up on foundations we laid, with no handover between contractors.
-
5Hand over
Finished, signed off and handed over, with one point of contact throughout.
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 and fully insured, with CSCS, CPCS and Street Works certification
