Modern Monticello

Common Builds

The MM build catalog — Ogopogo's modular structural system and the off-grid appliance line it connects to, each with a five-tier ladder from Settler to Mythic. Most of these are still concept-stage, pending real engineering sign-off before construction — that status is called out on each card, not glossed over.
Modular Papercrete/Geopolymer Post-and-Panel System

The Ogopogo

One universal connector standard, so any structural module — deck tile, stair tread, wall panel — mates to any post. The parts library the rest of the MM build system is built on.

Thermal Mass Heater System

The Snawfus Hearth

A double-bell masonry heater — the Russian stove's slow-release thermal mass, achieved through two stacked heat-exchange chambers instead of a fragile serpentine flue. Already specified for Greenbrier Getaway.

Modular Cast Masonry System

The Melonhead

One interlocking stud/pocket grid under three cast unit shapes — brick, structural block, and rocket-mass-heater flue — so a wall, a footing, and a heater's flue all key into the same registration system.

Einstein Absorption Refrigerator

The Snow Wasset

A heat-driven fridge with zero moving parts, running the 1930 Einstein-Szilard cycle — and the heat source is agnostic: burner, gas line, grid element, solar thermal, or waste heat off another system already running.

Passive Insulated Cooler

The Grafton

No fluids, no power — a 3D-printed, panelized liner inside a cedar box, sealed and foam-filled. The only capital cost to open the whole product line is a ~$150 consumer FDM printer.

Water Catchment System

The Uktena

Every MM roof is already standing seam metal — the best catchment surface there is. This line doesn't add infrastructure, it captures what's already hitting the roof, in a terraced cistern cascade.

Washing Machine

The Flatwoods

Closes the water loop — the Uktena catchment supplies it, and its greywater output routes back to the food forest. Power scales from hand crank to pedal to low-draw DC; no tier requires a grid hookup.

Cedar Chest Clothes Dryer

The Nunnehi

A cedar chest that dries clothes instead of just storing them — heat-trapping cabinet, self-powered thermal fans, no electric dryer motor at any tier. Doubles as linen storage on days it's not drying anything.

Wood-Fired Hot Tub

The Ogua

The catalog's first pure pleasure build — everything before it sold on utility or independence. Cedar and copper, heated by an external firebox through a pump-free thermosiphon loop, filled off the same cascade and draining to the same food forest as everything else.

Micro-Hydro Power System

The White Thang

Solar's real cost driver isn't the panels, it's the battery bank needed to bridge cloudy stretches — a well-sited creek delivers steady, near-continuous output no solar array can match on its own, cutting how much buffer the rest of the power stack has to carry. Pairs with the Snawfus Hearth's winter leg and the property's solar/battery hub under the redundant power stacking rule: no single system has to be the hero.

Yarrow-Stalk I Ching Casting Set

The Pukwudgie

Fifty hand-milled cedar stalks and a length of hemp cord — the full classical stalk-counting method for casting an I Ching hexagram, built instead of bought. Companion build to the I Ching guide on Common Ground.

Tongue-and-Groove Plank Fabrication Jig (Zach's Method)

The Leshy

Interlocking log-cabin-style planks from pallet wood and homemade glue, no router or milling equipment required — the joint is entirely hidden once assembled.

Cross-Braced Truss with Center Rain Channel + Vent

The Raiju

An X-braced open-air truss that catches and channels rain down its own spine while the perpendicular gaps vent passively — built with the holes, not against them.

Kang-Style Heated Sleeping Platform (Bed Stove)

The Domovoi

A masonry bed that stays warm for hours after the fire's out — one firebox heats both the room and the mattress. Traditional in northern China and Russia.

Horizontal Chimney Heated Bench/Platform (Hypocaust-Style)

The Salamander

Hot gas runs sideways through a masonry mass before it ever reaches the chimney — a bench or floor that holds a fire's heat long after the flame is gone.

Flue-Through-Mass — The Shape Behind Every Thermal-Mass Heater

The Selkie

One skeleton, wearing a different skin every time — floor, bed, bench, wall, or oven surround, it's the same shape underneath.

One Firebox — Space Heat, Water Heat, and Trickle Power

The Hydra

Three outputs from a single fire: thermal mass for the room, a thermosiphon loop for hot water, and a thermoelectric module trickle-charging small devices off the same heat.

Self-Supporting Interlocking Log Arch (Carport / Hoop House)

The Bifrost

A timber arch that holds itself up through interlocking friction alone — no fasteners at the crossing joints, covered with tarp or greenhouse film for a carport, hoop house, or covered patio.

Dead Hedge (Benjes Hedge) — Brush Barrier

The Bogle

A fence built entirely from yard waste — stakes and woven brush, no purchased material beyond the stakes — that doubles as wildlife habitat and a slow-release compost windrow.

Earth-Sheltered Greenhouse — Ground Thermal Mass + Glass Roof (Walipini)

The Sídhe

A greenhouse built into the hillside itself — earth walls hold the day's heat and release it slowly overnight, extending the growing season without burning anything.

Small Builds & Homestead Systems

Weekend-scale builds and animal/pollinator systems, ready to build now — no engineering sign-off pending, just the manual.

Easy · 2–3 hrs · $15–25

Cedar Birdhouse

The first rung on the builder ladder — one board, screwed joints only, sized so a kid can run the tools under supervision and rebuild it if a cut goes wrong.

Very Easy · 30 min · $8–15

Terracotta Olla

Two stacked terracotta pots that water a garden bed for a week on one fill — ancient technology that delivers water straight to the roots with zero runoff and zero moving parts.

Moderate · 4–5 hrs · $40–60

Cedar Garden Planter

The first food-growing build on the ladder — bigger stock, real joinery, and a box that's still producing after the sawdust settles.

Easy to Moderate · 6 hens = ~$265–510 startup

Chicken Coop System

A 6-hen backyard flock produces 30+ eggs weekly, 3 lbs of manure daily, and meat birds on top — provided the coop is genuinely predator-proof, which is non-negotiable, not a nice-to-have.

Easy to Moderate · ~$65–105 per hutch

Rabbit Hutch System

The best feed-to-meat conversion of any common homestead animal (3:1), silent enough for close neighbors, and closes the loop completely — garden waste in, meat and hot manure out.

Very Easy · ~$65–100 per hutch

Quail Hutch System

The urban homesteader's animal — silent, stackable, and a single female lays 300+ eggs a year from a footprint measured in square inches, not square feet.

Moderate learning curve · ~$60–120 DIY top-bar hive

Beehive & Pollinator System

Bees are pollination infrastructure first and a honey source second — a garden with an active hive sees 20–50% higher yields, a value that outstrips the honey itself.

Easy · 1–2 hrs · Free from butchering scraps

Rendered Tallow

Beef fat, water, and low heat turn into a shelf-stable base for soap, skincare, and cooking — a standard wet-rendering method, nothing exotic about it.

Advanced · Several days · Free from a fresh hide

Home-Tanned Rawhide

Wood ash loosens hair the same way lime does in commercial tanning — a real, complete rawhide process from a fresh hide to a finished, pliable sheet.

Homesteader · A few hours · Free from scrap hardwood

DIY Biochar

Burning hardwood with limited oxygen produces biochar — a genuinely useful soil amendment, but not the medical-grade activated charcoal some source pins wrongly call it.

Very Easy · 30 min · Free from scrap wax and shavings

Wax & Wood Shaving Fire Starters

Wax-saturated wood shavings in an egg carton mold — a reliable 8–10 minute burn to get a fire going without lighter fluid.

Very Easy · 20 min · $10–20 for two unglazed pots

Zeer Pot Evaporative Cooler

Two terracotta pots and wet sand cool produce by evaporation — Zach runs one on his own deck, and confirms it's a mild-cooling novelty in WV's humidity, not real refrigeration.

Easy · A weekend · $50–150 per 100 sq ft

Reflective Roof Coating (Cool Roof)

A white or aluminum elastomeric coating that reflects sunlight instead of absorbing it — the single easiest first fix for a hot WV roof, per Zach's own call on the MM Local property-walk wizard.

Moderate · A day · $80–250

Attic Vent Fan Install

Pulls hot, stuffy attic air out through the roof so it stops radiating heat down into the living space below — a real fix, but only if there's enough intake venting to back it up.

Moderate · Weekend+ · $200–600

Earth Tube (Ground-to-Air Heat Exchanger)

A buried intake pipe that pulls outside air across stable underground soil temperature before it ever reaches the house — free pre-tempering, no moving parts beyond an optional fan.

Moderate-Advanced · Multi-day · $400–2000+

Cistern & Rainwater Catchment System

Catches what already falls on your roof for free, year-round, instead of paying the water company for it — gutters, a first-flush diverter, a storage tank, and a pump to get it back out.

The working animal fleet — 1 machines from Working Animal through Mythic tier, each named for what it actually does.
