Architects and engineers on one team.

Hillsborough is one of Somerset County's largest townships, covering about 55 square miles between the Sourland Mountain and the Raritan and Millstone rivers. Roughly 40 percent of its land is protected or preserved open space, so homes range from suburban subdivisions to properties with real acreage.

Projects here often involve adding a family room, a primary suite or a full second floor, along with the structural work that makes those changes possible.

Local considerations

Site and structure in Hillsborough.

In New Jersey, most additions and structural renovations need zoning approval from the town before the construction permit, and the construction permit itself is reviewed under the state Uniform Construction Code. When a design needs relief from a setback, coverage or height limit, it goes to the town's land use board for a variance hearing.

On the Sourland side of the township, rocky ground and slopes affect footing design, grading and drainage. Near the rivers, low lying properties may fall within mapped flood areas. We check both during the first site visit so the design accounts for them from day one.

Larger lots often bring septic and well systems, which limit where an addition can go. We locate them early and plan the footprint around them.

However your project is approved, we deliver signed and sealed drawings to you, support you and your contractor through the permit submission and answer the building department's review comments in house. Read how a project moves from consultation to close out on our process page.

Questions

Hillsborough homeowners ask.

My house has a septic system. Can I still add on?

Usually, but the addition has to stay clear of the system and its required separation distances. We locate it early and design the footprint around it.

Is Belle Mead in Hillsborough or Montgomery?

Belle Mead spans parts of both townships. We confirm which municipality and zone your property is in before design starts.

Can you add a second floor to a split level?

Often, yes, after we check the existing structure and design any reinforcement.
