Let the transformation begin.

The concept is surprisingly simple - rather than starting from scratch onsite, we construct your second storey in a purpose-built facility offsite, fusing the advanced thermal properties of EPS with the enduring quality of engineered steel in a controlled environment shielded from the elements. Once completed, we’ll transport it to your property, using a crane to secure it to your home within a single day, before connecting services and installing your staircase in the coming weeks.
