Yes — Expandify homes are suitable for moderately sloped sites thanks to our BMSA footing kit and adjustable steel stumps.
Key limits:
Slopes up to 250mm per 5 metres are permitted without cut and fill
Finished floor height can be elevated up to 900mm on H1-class soil
Additional engineering is required for P, M, or H2-class soil types or steeper grades
All slope suitability is confirmed during the Site Assessment. Sites with significant fall may require excavation, retaining, or crane access modifications.
