Custom Metal Barndominium Contractors Broaddus Texas

Down around Broaddus, near the shores of Lake Sam Rayburn, acreage living is all about kicking back, keeping chores simple, and having a secure spot to park your camper or boat. Not everybody needs thousands of square feet to keep clean—a lot of folks just want a well-insulated, stout little home base with plenty of covered outdoor space to enjoy the timber. Our crew recently wrapped up this custom tiny home steel barndominium right out in Broaddus, Texas, engineered with a sharp modern colorway and a tall, attached RV porch built to keep rigs out of the weather.

Here is a look at the layout, materials, and smart acreage design behind this San Augustine County build.

Project Overview & Exterior Styling

A compact footprint doesn’t mean skipping on durability or curb appeal. The clean neutral tones and unpainted metal roof blend right into the pine country while standing up to the elements:

  • Structure Style: Custom engineered residential tiny home barndominium
  • Primary Wall Panels: Ash Gray heavy-gauge steel siding
  • Roofing System: High-reflectivity Galvalume metal roof
  • Trim Package: Bold black corner trim, fascia, window framing, and gutter accents
  • Standout Feature: High-clearance attached covered steel RV porch
  • Location: Broaddus, Texas (San Augustine County / Lake Sam Rayburn area)

The Ash Gray siding paired with black trim gives the home a sharp, defined outline from the county road, while the raw Galvalume roof works hard overhead. Unpainted Galvalume reflects harsh summer solar radiation better than almost any standard roofing material, keeping heat buildup out of the living space and helping the air conditioner breeze through July and August.

Standout Feature: The Integrated Covered RV Porch

The defining element of this Broaddus project is the high-clearance, heavy-duty metal porch structure tied directly into the home:

  • Dual-Purpose Living & Parking: Instead of paying high monthly fees at an RV storage yard, the owner has a dedicated, covered pull-in bay right next to their front door. It keeps travel trailers, fifth-wheels, or bass boats protected from relentless sun, falling pine sap, and severe hail storms.
  • All-Weather Outdoor Living: When the RV is out on the road or parked back, that massive covered porch turns into an expansive outdoor breezeway. It’s an ideal shaded spot to clean fish, fire up the smoker, hang a couple of rocking chairs, and visit with company out of the direct sun.
  • Tied into the Structural Frame: Rather than using a lightweight add-on kit that might shake in a storm, the tall RV porch is engineered with the same heavy-duty steel framing as the main residence, anchored solidly into concrete footers to stand up to heavy straight-line winds.

Built Stout for San Augustine County Living

Whether you’re tucked in the woods or sitting close to the water, East Texas ground and humidity can be brutal on traditional wood-frame cabins. Building with steel solves those headaches right from the start:

  • Reinforced Concrete Foundation: A monolithic slab poured with deepened perimeter beams and rebar cages provides a level, immovable base that resists shifting in local soils and supports heavy point loads from parked rigs.
  • Sealed Tight Against Humidity: We insulated the living quarters with closed-cell spray foam applied directly to the metal skin. This creates an airtight moisture barrier that locks out high humidity, quiets down heavy rainstorms on the Galvalume roof, and makes the small space incredibly cheap to heat and cool.
  • Zero Termites or Rot: Damp wood invites wood-boring pests and moisture decay. Structural steel and commercial metal panels never rot, warp, or attract pests, leaving you with virtually zero exterior maintenance chores.
  • Open Interior Layout: Clear-span engineering means no load-bearing interior partition walls. In a tiny home, this allows every single square foot to be put to good use for an open-concept living room, kitchen, bath, and cozy sleeping quarters.
