Thinking about buying a lot with a view? Sloped land can result in stunning architecture — but it requires specialized planning and construction to avoid problems down the line.
What to Expect When Building on a Slope
- Excavation and Grading
- A sloped site often requires major earthwork to create a stable foundation. This can include removing or adding soil, which increases costs and timeline.
- Drainage and Retaining Walls
- Proper drainage is critical. Without it, water runoff can damage the foundation. Retaining walls are often needed to manage elevation changes — and must be structurally engineered to code.
- Custom Foundation Solutions
- Steep lots often require deeper foundations or piers. A flat slab won’t cut it — we design foundations that fit the topography while staying structurally sound.
- Access and Driveway Design
- Slopes affect everything from garage placement to how guests park. A steep driveway may need special grading, heated surfaces, or even switchbacks to ensure safe access.
