Custom House Plans in Portland, ME - Legacy Construction

Every home we build starts with a plan, and every plan we produce starts with how you live. We develop custom architectural designs for homeowners across Greater Portland and Southern Maine: lifestyle-centered floor plans, 3D visualization, and full construction documents engineered for Maine's climate and ready for permit submission and construction.

A custom house plan is not a starting template you modify. It is a design built from scratch around your life, your lot, and Maine's specific building requirements.. That distinction determines whether your home works the way you imagined or requires compromises you did not anticipate. Legacy Construction starts with how you live and designs outward from there.

What we bring to every project:

  • We show up when we say we will
  • We build exactly what we said we'd build
  • We never leave a project unfinished

Legacy Construction built an addition onto our home, and the quality is outstanding. The new space blends perfectly with the original house. They worked with us on budget and design and were always upfront about costs and options. Very professional from start to finish.

From the first meeting, Legacy Construction was honest, professional, and easy to work with. They walked us through budget, design, and expectations clearly and followed through on everything. The end result is a beautifully built space that feels solid and well thought out.

Legacy Construction Service Area

Designed around how you live. From blank lot to permit-ready documents.

Every plan we produce starts with your lifestyle and your lot. We develop designs built for Maine's climate and refined with you before producing construction documents ready for permit submission.

  • Site Visit, Design, and Full-Scope Construction

    It starts with a site visit where we evaluate your lot, discuss intended use, and identify setback constraints, drainage, and utilities. We design around your specific needs — whether that is a two-car heated garage, a multi-bay collector space, or a structure with attic storage above. Joe Hausler reviews every plan personally before we build. Every garage includes excavation to four-foot frost depth, foundation, framing, roofing, siding matched to your home, electrical, overhead doors, and concrete flatwork.

  • Commercial-Grade Planning for Your Garage Build

    Joe Hausler spent 15 years managing commercial builds up to $300 million before founding Legacy Construction. He brings those planning systems and quality control standards to every custom garage we build in Southern Maine. Every garage gets a fixed-price contract before we break ground, a five-year workmanship warranty when we walk out, and Tim Schofield's finish carpentry on every interior detail. Most builders cannot say any of those three things. We can say all of them.

  • Cost, Timeline, and What a Legacy Garage Delivers

    Custom garages in Southern Maine typically range from $55,000 for a standard two-car build to $150,000 or more for a multi-bay heated space with premium finishes. Timelines run eight to fourteen weeks from groundbreaking to walkthrough. Legacy Construction provides a fixed-price contract before breaking ground and backs every garage with our 1-year materials, 2-year systems, 5-year workmanship, and 10-year structural warranty package. We recommend starting design in late winter so construction begins in spring and wraps before fall.

We coordinate all design phases, structural engineering, and permit documentation so your project starts with a solid foundation. Contact us to begin your design process.

Frequently asked questions regarding Custom House Plans

  • Do you need a permit to build a garage in Southern Maine?

    Yes. Every new garage build in Southern Maine requires a building permit through your local code enforcement office. State electrical and plumbing permits are also required separately. Most municipalities process residential building permits within one to three weeks. Legacy Construction handles every permit application, inspection scheduling, and code coordination from start to finish so you never have to chase paperwork between offices.

  • How long does it take to build a custom garage in Southern Maine?

    Most custom garage builds with Legacy Construction run eight to fourteen weeks from groundbreaking to final walkthrough. Larger or more complex builds — multi-bay collector spaces, heated floors, full workshop systems — can reach sixteen to eighteen weeks. The most common schedule variables are ledge discovery during excavation, engineered truss lead times of three to six weeks, and state electrical inspection scheduling. We build all of these into the timeline before we break ground so there are no surprises mid-build.

  • How much does a custom garage build cost in Southern Maine?

    Custom garage builds in Southern Maine typically range from $55,000 for a standard two-car build to $150,000 or more for a multi-bay collector space with heated floors and premium finishes. The biggest cost drivers are foundation conditions, electrical scope, insulation and heating systems, siding material, and garage door quality. Legacy Construction provides a fixed-price contract before breaking ground so you know exactly what you are investing before the first shovel goes in. Every garage is backed by our full warranty package.

  • Do you build detached and attached garages in Southern Maine?

    Yes. Legacy Construction builds both detached and attached garages across Greater Portland and Southern Maine. Detached garages are freestanding structures on their own foundation. Attached garages share a wall with the main home and require fire-separation assemblies between the living space and the garage. We handle both types with the same process — site evaluation, design, fixed-price contract, and full construction management from excavation through final walkthrough. Every garage is backed by our full warranty package.

  • What warranty does Legacy Construction provide on garage builds?

    Every custom garage Legacy Construction builds is covered by our comprehensive warranty package: 1 year on materials, 2 years on systems, 5 years on workmanship, and 10 years on structural coverage. The five-year workmanship warranty is five times longer than Maine's standard one-year requirement. If something we built is not right, we come back and fix it. Everything is documented in writing before any garage project begins. We build garages meant to stand for generations — and our warranty reflects that commitment.

  • What should we expect during a Legacy Construction garage build?

    When a Legacy Construction garage build begins, you will see a crew on site at the scheduled time with a clear plan for each phase. Joe Hausler is on site multiple times per week. Jonathan Henshaw coordinates every trade — excavation, foundation, framing, roofing, electrical, and concrete — so trades flow into each other without gaps. Tim Schofield handles every finish detail inside the garage. We provide weekly progress updates, communicate any discovery or condition change before we act on it, and keep the site clean and organized throughout.
