The main structure.

The barndo is the heart of the compound — primary residence for Jeff & Denise, home for Kona & Colten, and Kyle's interim residence until his supplementary structure is built. It also holds the shared kitchen and common space. Texas has more barndo builders than any other state, so the choice isn't whether to find one; it's filtering between dozens of comparable options.

Design Examples

Five style directions worth shortlisting before talking to builders. Each comes with a recognizable visual language that drives finish costs.

• Modern Farmhouse Barndo — the dominant Texas style. White or natural wood board-and-batten siding, black trim, standing-seam metal roof, deep wraparound porch. Open great room with vaulted ceiling.
• Industrial Modern Barndo — exposed steel framing celebrated as a feature, factory-style windows, polished concrete floors, minimal partitions. Reads more like a converted warehouse.
• Hill Country Barndo — limestone accents, dark cedar beams, copper or weathered metal roof, deep porches with stone pillars. Blends with the cedar-and-limestone aesthetic from Salado through Wimberley.
• Traditional Ranch Barndo — lower-profile gable, longer footprint, single story, deep eaves. Inspired by the working ranch barn aesthetic. Functional and unpretentious.
• Two-Story Loft Barndo — vaulted main living below, sleeping loft above, often with mezzanine. Maximizes square footage on a smaller footprint. Strong fit for a compound where the main barndo houses both common area and private wings.

Texas Styles, Limitations & Features

Central Texas climate and building codes dictate a handful of non-negotiables. Skipping them looks like a savings at quote time and costs three times more in remediation later.

Climate must-haves

• Spray foam insulation throughout — open-cell minimum, closed-cell on the roof line. Texas summers punish anything less.
• Standing-seam metal roof — 50+ year lifespan, hail resistance up to Class 4 impact rating, dramatically lower insurance premiums.
• Tinted Low-E windows — the difference between a livable space and an oven.
• Wraparound porch facing west or south — passive sun protection that the architecture pays back ten-fold over the building's life.
• Mini-split HVAC zoning — cool only the rooms you're using; barndo open volumes are too large to cool monolithically.

Foundation

Slab-on-grade is the standard. No basements in Central Texas — high water table and expansive clay make them impractical. In areas with expansive soils, upgrade to a post-tension slab; the added engineering handles soil heave.

Wind & insurance

Bell County sits in Wind Zone II under the International Residential Code. Reputable barndo builders engineer for a minimum 110 mph base wind rating. Tornado risk in the I-35 corridor is lower than Oklahoma, but hail is the dominant claim driver. A Class 4 hail rating on the roof and impact-resistant glazing pay back in lower premiums year over year.

Permitting (Bell County)

• Outside Belton, Temple, Killeen, and Salado ETJs: typically no building permit. OSSF (septic) permit, electrical inspection, and any commercial component (commissary kitchen, public studio) get separate review.
• Inside city ETJ: setback, fire-marshal sign-off, and architectural review apply.

Cost reference (2025 ballpark)

• Mueller barndo shell (40×60, steel + roof, no interior): $35K–$55K
• Turnkey 2,000–3,000 sqft barndo, finished interior, mid-range finishes: $180–$280/sqft
• Comparable stick-built in Bell County: $200–$320/sqft

Texas Builders

Texas-based or Texas-active firms with real reputations behind their barndo work. Get bids from at least three before signing.

Prefab & Kit Suppliers

Kit-only typically lands at 60–70% of comparable turnkey pricing. The trade-off: you arrange foundation, erection labor, MEP (mechanical/electrical/plumbing), and interior finish separately.

The secondary dwellings.

Accessory Dwelling Units handle the housing pieces that sit outside the barndo: one for Susan, possibly one for Kyle, and potentially a guest unit. Smaller envelopes mean cheaper construction per square foot, faster timelines, and more design flexibility than the main barndo.

Design Examples

• Detached Studio Cottage (300–600 sqft) — one open room with kitchenette and bath. Cheapest and fastest. Strong fit for Susan or short-term guests.
• One-Bedroom Casita (500–800 sqft) — separate bedroom, living area, full bath, full kitchen. Standalone livability — could be rented or host long-term.
• Two-Bedroom ADU (800–1,200 sqft) — two beds, one or two baths, living, full kitchen. Designed for Kyle long-term or for adult children with a partner.
• Garage Conversion or Above-Garage ADU — built above a workshop or detached garage. Doubles utility — work below, sleep above.
• Modern Modular ADU — factory-built, delivered on a truck, set on a slab in days. Brands like Cover, Method, and Plus Hus are doing 600–900 sqft units in this format.
• Tiny Home on Foundation (under 400 sqft) — permanently affixed. Crosses into "park model" classification in some jurisdictions; verify with Bell County before designing.

Texas Styles, Limitations & Features

Texas ADU economics are friendlier than the barndo because the smaller envelope makes everything cheaper to handle.

Features

• High-SEER mini-split HVAC is the standard. One unit can efficiently handle a 600 sqft space.
• Same envelope rules as the main residence: spray foam, metal roof, Low-E windows.
• Universal design (zero-step entry, 36" doorways, walk-in shower) if Susan or other older family members will live in it. Costs little extra at build time, expensive to retrofit.

Limitations

• Bell County unincorporated: ADUs are essentially unrestricted as long as you pass septic permitting and have utility access. The main practical limit is septic load.
• Belton city ETJ: ADUs allowed but subject to setback, parking, and owner-occupancy rules. Verify before designing.
• Lender angle: Fannie/Freddie now allow ADU rental income to count toward primary mortgage qualification. Useful if any of the build is financed.

Septic sizing

Bell County requires OSSF sized for the total bedroom count across all dwellings on the parcel. A 3-bedroom barndo plus a 1-bedroom ADU = 4 bedrooms = larger system. Design the septic capacity for every ADU you might add later, on day one — adding capacity later is dramatically more expensive than oversizing up front.

Utilities

Separate electrical sub-panel branched from the main feed. Water and septic typically shared with the main house. Permanent ADUs increase the property tax basis.

Prefab & Kit Builders

Modular ADUs ship more readily into Texas than fully site-built units. Lead times run 4–8 months from order to delivery, plus 2–4 weeks of site prep and hookup.

Texas Builders

Texas ADU specialists are clustered in Austin (post-2023 zoning changes drove a small boom). Bell County builders are typically generalists who'll work to any plan.

The other buildings on the land.

Beyond the barndo and ADUs, two structures play meaningful roles in compound life and the on-property businesses: the chicken coop and the DD's Baked Goods honor-stand.

Chicken Coop

Modest scope: 6–10 hens, primarily for eggs plus bug control on the disc golf course. A rooster is optional and only advisable if neighbors are well distanced.

Design

• Allocate 4 sqft per hen inside the coop and 10 sqft per hen in the run. Eight hens calls for roughly a 32-sqft coop with an 80-sqft attached run.
• Nesting boxes: 1 per 3–4 hens, dark and slightly elevated.
• Roosting bars: round dowels or 2×4s laid flat-side-up so the birds can fully cover their feet in winter.
• Ventilation up high (heat rises) without drafts at chicken level. This is the single most-missed detail in DIY builds.
• Predator-proofing: hardware cloth, not chicken wire — raccoons can rip standard chicken wire. Bury a 12-inch perimeter skirt of hardware cloth. Use carabiner-style latches; raccoons defeat hooks.
• Central Texas climate adaptations: shade over the run, interior fans, optional summer misters. Heatstroke is the leading cause of preventable hen death in TX.

Placement

• Downwind of the barndo and ADUs. Even a clean coop has a smell.
• Near a water source for waterer refills.
• Not directly under tall trees that attract hawk perching.
• Well-drained ground — chickens despise mud, and wet runs cause foot disease.
• Setbacks: 50+ feet from septic field, 100+ feet from any water well, 25+ feet from property lines.

Land considerations

• Bell County predator load: coyotes, raccoons, opossums, snakes, owls, and red-shouldered hawks. A 6-foot perimeter fence around the run with an overhead net handles most of it.
• Free-range or rotational grazing: consider electric poultry netting (Premier 1 is the standard brand) so the flock can be moved around the compound for bug control without losing them to predators.
• Manure composting: high-nitrogen, excellent for the garden, but needs three months of aging before going on edible plants.

Legal

• Bell County unincorporated: poultry are essentially unregulated for personal use. Roosters are permitted.
• Egg sales: Texas exempts on-farm direct sales of under 30 dozen per week from licensing. Above that threshold, register with the Texas Department of State Health Services (DSHS).
• USDA does not regulate personal-flock egg production.
• Ag exemption (1-d-1): chickens alone won't qualify a parcel, but they fit alongside bees, hay production, or rotational grazing as part of a broader ag operation that could.
• Verify deed restrictions on the specific parcel — uncommon in rural Bell County but possible.

Build options

• Kit coops (Tractor Supply, Amazon): $400–$1,500. Light-duty; predator upgrades usually needed.
• Mid-range custom build: $1,500–$4,000.
• Premium fixed coop with run: $5,000–$10,000.
• DIY plans (Carolina Coops, BackYard Chickens community): under $1,000 with reclaimed materials and a long weekend.

DD's Bakery Shed / Trailer

The retail face of DD's Baked Goods — Series A under the compound's Series LLC umbrella. Denise bakes from the main barndo kitchen; finished goods live in a small honor-stand where neighbors, drive-by traffic, and disc-golf visitors pay via cash slot or QR code. Restocked on a regular cadence as fresh batches come out.

Stationary vs. trailer

• Stationary shed — bigger, more display and storage, no towing. Best near the property entrance where it catches drive-by traffic. Treated as a small outbuilding for any permitting purposes.
• Trailer-mounted — can travel to farmers markets, festivals, wedding popups, and disc-golf tournaments. Smaller capacity, requires a tow vehicle, possible TxDOT registration depending on weight.
• Hybrid — primary stationary structure on the compound plus a separate small trailer for events. Maximum reach, double the build cost.

Design considerations

• Climate control is non-negotiable. Texas summer heat ruins baked goods in hours. Plan for a mini-split, window AC, or solar-powered ventilation. At minimum, limit restock hours to early morning and store reserves in the cooler back-room.
• Display shelving: clean, easily wiped, sloped so customers see goods clearly.
• Optional small refrigerated case if expanding into items that benefit from chill — though Cottage Food items by definition should not require refrigeration for safety.
• Lockable for off-hours.
• Pest-proofed construction: tight seals, vermin-grade door sweeps, no gaps. Mice are the real enemy.
• Lighting: solar-LED works well for off-grid placement; bright enough for early and dusk shoppers.
• Signage: branded "DD's Baked Goods," clear price posting, clear payment instructions ("Drop cash here, or scan to pay").

Honor pay mechanics

• Cash lockbox bolted to the interior, slit-only deposit, key access from a hidden back panel.
• QR codes prominently displayed: Venmo, Cash App, and Square. Bigger is better — readable from arm's length and at low light.
• Posted per-item or per-tier pricing ("All loaves $8 · Cookies $4 · Specials priced individually").
• Security camera (Ring, Blink, Wyze) — primarily a deterrent and a tool for spotting restocking patterns. Rural honor stands historically run 80–95% pay rates.
• Receipt option: a "tap for a digital receipt" QR for buyers who want it; otherwise anonymous. Square's dashboard handles the tax-reporting side automatically.

Construction options

• Pre-built portable shed (Tuff Shed, Lifetime, Suncast): $2,000–$8,000. Easy starting point; needs climate-control upgrades.
• Shipping container conversion: $3,000–$15,000 base plus finish-out. Indestructible, simple to insulate, looks more permanent.
• Custom small structure on slab: $5,000–$15,000. Maximum design control. May trigger ETJ permitting depending on size and location.
• Concession trailer (new or used): $3,000–$25,000. Built for food service and easier to hook up, but inspection requirements jump substantially the moment it's classified as a food truck.
• Vintage trailer restoration (teardrop, Airstream, Shasta): cost varies widely. High brand appeal, more involved build, strong fit if DD's runs a market booth presence.

How to make a decision.

1. Pick a shortlist of 2–3 styles per dwelling (barndo + at least one ADU shape).
2. Get three bids per shortlisted approach: one regional GC, one named-brand turnkey, one kit + local-GC combo.
3. Confirm OSSF permitting at the parcel before committing — septic capacity is the hardest constraint to retro-fix.
4. Lock finish-level decisions early (cabinetry tier, flooring tier, fixtures). Mid-project finish upgrades are where budgets explode.
5. Sequence kit orders ahead of slab work — 8–16 week lead times on steel kits in 2025.
