Custom Homes

Custom Homes in Southeastern Pennsylvania

Walnut Hill Heritage Builders builds new custom homes with the proportions, materials, and permanence of the region’s best old houses, made for modern life. We work with owners and architects on new homes on farmland, wooded lots, and historic properties across Berks, Lehigh, Bucks, Montgomery, Chester, and Lancaster counties.

What does a custom home with heritage character mean?

It means building a new house with the same logic that made the region’s old houses last, not borrowing a style and applying it to a standard build. The stone farmhouses and bank houses of southeastern Pennsylvania look the way they do for reasons: thick walls, simple rectangular forms, steep roofs that shed snow, and careful placement on the land. A new home that understands those reasons can feel settled on its site from the day it’s finished.

What gives a house regional character?

A few features do most of the work, and they are easy to get wrong:

  • Massing and proportion. Traditional houses here are mostly simple, rectangular volumes, often with symmetrical facades and later-looking wings. Proportion matters more than ornament.
  • Real depth at the walls. Old stone walls produce deep window and door reveals. Thin veneer over a standard frame wall can’t reproduce that shadow line, which is why many new “stone farmhouses” look flat.
  • Roofs. Steep gable roofs, tight rakes, modest overhangs, and materials such as slate, standing-seam metal, or wood shingle. Pent roofs, the shallow roof ledge between floors common in the region, work only when their proportions are right.
  • Windows. True divided lite windows with appropriate muntin widths, set deep in the wall, rather than grilles sandwiched between panes.
  • Chimneys and gable ends. Substantial stone or brick chimneys, often at the gable ends, anchor the house visually.

Siting on Pennsylvania land

Early builders placed farmhouses carefully. Many face south or southeast to catch winter sun, sit into a slope for shelter, and stand near a spring. Bank barns were built into hillsides so wagons could reach the upper floor. When we review a site, we look at the same things: sun, slope, prevailing wind, drainage, views, and how the house relates to any existing buildings.

Rural sites bring practical questions too. Many need an on-lot septic system and a private well, both of which depend on soil and water testing. Some farmland carries agricultural preservation or conservation easements that limit where, or whether, a house can be built. Driveway access, stormwater rules, and zoning setbacks vary by municipality. We raise these early, before design gets ahead of the site.

Building for generations

A house meant to stand for generations has to be built to last longer than a typical new home. That shows up in the structure (properly sized framing, sound foundations, good drainage), in the envelope (a continuous drainage plane, careful flashing, and moisture-tolerant assemblies behind stone), and in the materials (slate, copper, lime-based mortar, durable wood species). These choices cost more at the start, and we explain where they pay back over decades.

What we do

Our custom home work includes:

  • Site and feasibility review, covering zoning, septic, well, access, easements, and orientation, before you commit to a design.
  • Design coordination with your architect, including early pricing, constructability review, and material recommendations.
  • Foundations and drainage designed for the specific site, including hillside and walkout conditions.
  • Full-bed stone masonry with mortar and stone chosen to match regional traditions, along with chimneys and stone details.
  • Timber framing for great rooms, porches, and exposed structure, with traditional joinery where it suits the design.
  • High-performance envelopes with continuous air barriers, insulation, and controlled ventilation behind traditional exteriors.
  • Roofing in slate, standing-seam metal, or wood shingle, with copper flashings and gutters.
  • True divided lite windows and custom doors set at traditional depths.
  • Interior millwork, stairs, and built-ins designed and built to the house.
  • A complete house record documenting structure, systems, and materials at completion.

How we approach it

Our process applies to new homes the same way it does to old ones.

  1. Start with the site. The land decides a great deal: where the house sits, how it meets the ground, and what the approvals will require.
  2. Build the real thing. Where it counts, we use real stone, real divided lites, and real structure rather than imitations.
  3. Price as the design develops. Early and continuing pricing keeps the design and the budget aligned, so there’s no painful redesign after drawings are done.
  4. Detail for the long run. Water management, flashing, and durable materials are designed up front, because they determine how the house ages.
  5. Stay afterward. Through Heritage Care, the house record and ongoing maintenance keep the home in good condition long after move-in.

If your land already includes a historic barn or outbuilding, our barn and outbuilding conversions work may be part of the plan. If you’re weighing whether to build new or expand an existing house, see home additions and historic home restoration. We build throughout our southeastern Pennsylvania service area.

Common questions

Custom Homes: questions we hear

Do you build custom homes from our architect’s plans?

Yes. Most of our custom homes are designed by an architect the owner has chosen, and we prefer to join during design rather than after drawings are finished. Early involvement lets us price the design as it develops, flag details that are costly or risky to build, and suggest material and structural approaches that keep the house true to the design and to the budget.

Can you build a new house that looks like an old Pennsylvania farmhouse?

Yes, and the difference is in the details. A convincing farmhouse depends on simple, well-proportioned massing, deep window reveals, real stone laid with lime-rich mortar, correct roof pitches and overhangs, and windows with true divided lites. We focus on those fundamentals rather than applied ornament, so the house reads as rooted in the region rather than as a theme.

What should I check before buying land to build on in southeastern Pennsylvania?

Start with zoning, sewage, water, and restrictions. Confirm what the zoning allows, whether the soil supports an on-lot septic system through testing arranged with the local sewage enforcement officer, and whether a well is feasible. Check for conservation or agricultural easements, deed restrictions, floodplains, and wetlands. Requirements vary by municipality, so involve your attorney, surveyor, and township early. We can review a site with you before you commit.

Is real stone worth it compared with stone veneer?

For a house meant to last generations, often yes. Full-bed stone masonry is thicker, deeper at openings, and ages the way historic walls do, while thin veneer can look flat at corners and window returns. Real stone costs more in material and labor. We walk through where it matters most, often the main facade and chimneys, and where other cladding can serve well.

Can a new home with historic character also be energy efficient?

Yes. A new home isn’t bound by the limits of historic fabric, so we can build a tight, well-insulated envelope with controlled ventilation, modern windows, and efficient heat pump or hydronic systems behind traditional exteriors. The key is detailing, such as insulated stone walls with a drainage cavity and window installations that keep deep reveals without creating cold spots.

Can you build a new house on a property that already has a historic farmhouse or barn?

Often, subject to zoning and any easements. On older farm properties, a new house might sit alongside a historic farmhouse, replace a later structure, or incorporate a barn. We look at how historic farmsteads were arranged, including orientation, slope, and the relationship between buildings, so the new house fits the place. Some municipalities restrict second dwellings, so we confirm what’s allowed first.
