So you're trying to keep costs down, huh? The absolute cheapest option? That's gotta be a tiny house on a trailer or maybe just a simple barndominium shell. But if we're talking about a real, permanent foundation home, you're looking at a small, single-story rectangle with a basic gable roof, built with wood frame construction on a concrete slab. Honestly, it all comes down to keeping things simple—minimal square footage, cheap materials like vinyl siding and asphalt shingles. That's the ticket. Per square foot, you can't beat a barndominium or a simple ranch-style home. No complicated rooflines, no fancy dormers, just straight lines and cheap finishes. From what I've seen, a basic stick-built ranch runs you somewhere between $120 and $180 per square foot. A barndominium—that's a metal building turned into a living space—can get as low as $80 to $120 for just the shell. And then there's the tiny house on a trailer. Those can be $30,000 to $60,000 for 200-400 square feet, which works out to about $100 to $150 per square foot once you throw in appliances and finishes. Crazy, right? If you're pinching pennies, go with a single-story rectangle and a gable roof. That's it. No weird corners, no complex shapes—just a box. It saves on foundation costs, reduces roofing waste, and framing is a breeze. Adding a second story? That means stairs, floor joists, more structural stuff. Sure, a two-story might be cheaper per square foot for total living space, but total cost goes way up. For the absolute lowest total tab, think one bedroom, one bathroom, around 600 to 800 square feet. That's your sweet spot. Picking the right materials is huge. Here's a quick breakdown of what's cheapest for the big stuff: There's plenty you can do. Here's a list of tricks that actually work: The cheapest foundation? Hands down, a concrete slab on grade. No digging for a basement or building a crawl space. It's just poured concrete, usually 4 to 6 inches thick, with some wire mesh or rebar. For a small house under 1,000 sq. ft., you're looking at $4,000 to $8,000. that to a full basement—$20,000 to $50,000 or more. But watch out: slabs don't work everywhere, like places with deep frost lines. And fixing plumbing under a slab? That's a nightmare. Generally, a tiny house (under 400 sq. ft.) is cheaper overall—$20,000 to $60,000. But a small house (600-800 sq. ft.) can be cheaper per square foot because of economies of scale. Like, a 200 sq. ft. tiny house might cost $50,000 ($250/sq. ft.), while an 800 sq. ft. small house might be $120,000 ($150/sq. ft.). If you need more space, the small house wins on value per square foot. Cheapest roof is a gable roof with a simple pitch, like 4/12 or 6/12. A shed roof (single slope) is also cheap but might need more structural support. Stay away from hip roofs, mansard roofs, or anything with valleys and dormers—those just jack up labor and material costs. Yeah, it's possible, but you gotta be smart. A 400-600 sq. ft. tiny house or a barndominium shell can be built for $50,000 to $90,000. You'll need to do a lot yourself, use the cheapest materials, and skip any custom stuff. Labor's the big killer, so being your own contractor is key. Usually, yeah. The metal shell costs less than wood framing, and the open floor plan keeps things simple. A basic barndominium shell runs $80 to $120 per square foot, while a traditional home is $150 to $250. But finishing the inside—plumbing, electrical, insulation—can bring the total closer to a traditional house. It's best if you're willing to do the finish work yourself.Which is the cheapest house to build
