Hako

A complete dwelling in a U-Box envelope · 95 × 56 × 83.5 inches ·

The Hako (Japanese: 箱, "box") is the studio's catalogue capstone. A complete dwelling spec'd to deploy inside a U-Haul U-Box envelope — the same 37 sq ft / 2,000 lb container U-Haul ships across North America for moving and storage. Sleeps one or two. Cooks. Stores a year of belongings. Works as a primary residence in the right climate or a year-round ADU. The Hako is BXBX's proof that a serious dwelling fits inside a commodity envelope.

Interior architecture

A complete dwelling on four walls

The Hako interior is organized around a 34" central passage with four functional walls. Murphy bed deploys from one long wall; galley occupies the opposite long wall; KEEP wall (archive storage) anchors one short end; utility wall (power, water, ventilation) anchors the other. Every surface earns its place.

Wall 1 · Sleep

Murphy bed deploys from one long wall. Folded against the wall by day; full-size bed (54" × 75") at night. The bed's underside doubles as a desk surface when folded up.

Wall 2 · Galley

Opposite long wall holds the full kitchen: BDRC cooker, single-burner induction, small sink, prep counter. Above-counter cabinetry holds dish storage, pantry, and Wowlive shelving for STOCK cells.

Wall 3 · KEEP

One short end is the customer's archive wall. Three Wowlive 3-tier shelves arrayed vertically. Holds the customer's full 1646 cell library — documents, photographs, the entire physical record of a life.

Wall 4 · Utility

Opposite short end holds the power architecture, water system, ventilation, and weatherproof entry vestibule. The technical wall — everything mechanical lives here behind a removable panel for service access.

The 34" central passage The Hako's livability turns on a single dimension: the 34" central passage between the long walls. This is wide enough to walk through normally, wide enough to deploy the Murphy bed, narrow enough to keep every functional wall reachable from the center. Phase 0 mockup test verifies this dimension — a 4'×8' floor tape-out at the Dupont Arts studio with a weekend live-in before committing to a real build.
Power & utility

Off-grid summer, grid-supplemented winter

The Hako's power architecture inherits from the GROW01-OG-spec-v0.2 microsystem work. The Ryobi inverter ecosystem (800W Ryobi inverter or $40 third-party AC inverter compatible with Ryobi One+ 18V batteries) runs all dwelling loads off-grid in summer with solar supplementation. Winter operation assumes grid connection or generator backup for heating loads.

Phased build plan

From spec to livable dwelling

Phase 0 · Mockup

4'×8' floor tape-out at Dupont Arts studio. Weekend live-in to verify the 34" central passage livability. Refine interior plan before committing to a real envelope.

Phase 1 · Studio Hako

First real Hako built for studio use at Dupont. ~6–8 weeks builder time. Documents the build for future customer Hakos. Live photography for catalogue.

Phase 2 · First customers

Build-to-order Hakos for inaugural customers. ADU-focused initial market. Each Hako customized to its site and customer.

Phase 3 · Catalogue scale

Standardized Hako variants. Builder partnerships for cities outside Toronto. The Hako becomes a real product rather than a bespoke build.

Cross-practice integration

The Hako and the rest of the catalogue

The Hako is the studio's catalogue capstone because it integrates every other practice:

A customer buying a Hako isn't buying a single product. They're buying into the studio's full operating system — and that integration is the difference between a Hako and the dozens of tiny-house competitors selling envelope-only products.
