Most people look at a vacant lot and see a place to build a house.

We see everything that has to work together before that can happen.

For this new construction lot, Oakhill Engineering handled:

• Land surveying and plot plan
• Percolation testing for septic feasibility
• Septic system design
• Well location and setbacks
• Driveway layout and grading plan
• Overall site grading to make the lot buildable

All of these pieces have to fit perfectly before construction can even start.

This is the part of building a home most people never see — but it’s what makes the whole project possible.

If you’re thinking about building on a vacant lot, this is where the process really begins.
