From Pennington borough to Titusville, Harbourton and the slopes of the Sourlands, we design and engineer additions, renovations and new homes across the Hopewell Valley.
Hopewell Township is one of the largest municipalities in Mercer County, running from the Delaware River at Washington Crossing up into the Sourland Mountain region, with preserved farmland in between. It surrounds the boroughs of Pennington and Hopewell, which have their own walkable centers and older homes on smaller lots.
That range of settings shapes the work. An addition on a village lot in Pennington is mostly about fitting the plan within setbacks and respecting the street. A new home or a large addition on a rural Hopewell parcel is about the site: slopes, rock, drainage, septic and well locations, and how the house sits in the landscape. We handle both, with architects and engineers on the same team.
Licensed architects and professional engineers on one team, one contract and one set of signed and sealed drawings. See all of our services.
Rear, side and wraparound additions for kitchens, family rooms and primary suites, with the existing house evaluated by our engineers.
New floors over ranches, capes, garages and one story wings, with foundations and framing checked and reinforced as needed.
Whole house and partial renovations, wall removals and open plans, basements and attics, with structure and systems designed in house.
Ground up single family homes and teardown rebuilds, from site planning to sealed construction drawings.
Decks, covered porches, pergolas and garages engineered for footings, ledgers and loads.
Beam replacements, foundation fixes and engineer's letters for homeowners, buyers and insurers.
Hopewell Township has a Historic Preservation Commission, established in 2000, that oversees the Harbourton Historic District and designated landmarks such as the Titusville Store and the Marshall's Corner Schoolhouse. The Pleasant Valley Historic District, listed on the National Register, also extends into the township. If your property is designated, we plan for the Commission's review as part of the design schedule.
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.
In the northern and western parts of the township the Sourlands bring rocky soils and steeper ground. Footing design, retaining walls and drainage around a new addition get real engineering attention from our team rather than a typical detail from a standard set.
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.
No. Pennington is a separate borough, about one square mile, completely surrounded by Hopewell Township. Each has its own zoning and permit offices, and we work in both.
Not usually, but it needs engineering. We design footings, any retaining walls and drainage for the actual site so the addition performs and the contractor prices a complete design.
Yes. We look at the site first, including access, septic and well locations and grading, then design the house around it.
