What’s different about building on a hill?

A house built into hill requires a level platform to be excavated for stability, retaining the earth to prevent erosion, and implementing waterproofing and tanking to address ground water.
Seamless integration of these elements and attention to floor level height are crucial for a successful hillside construction.

How much does
a hill build cost?



It’s 20-30% more expensive for houses built on sloped land, to cover the spectrum of additional engineering, consultants, construction costs and waterworks. The steeper the site, the more the cost increases due to additional retaining walls and outdoor areas. The ground's slip-prone nature and rock content affect design possibilities and expenses, such as geo tech reports, water runoff, likelihood of natural groundwater courses.
