The Design Intent
The square footprint is the design decision that drives everything else in The Datum. At 21 by 21 feet, the layout has no long axis to bias toward — which sounds like a constraint but actually gives you more flexibility in how the interior gets organised. The result is 441 square feet that feels genuinely balanced: a main-floor bedroom for long-term livability, an upper loft for guests or a second occupant, and an open living area that doesn't feel like it was carved out of what was left over.
The shed roof keeps construction straightforward and allows for higher ceilings on one side, which the large windows take full advantage of. Light comes in from multiple angles throughout the day and the space stays bright without feeling exposed. As a primary residence, an ADU on an existing property, or a guest house with real separation between sleeping areas — this layout covers a lot of ground efficiently.
This design is perfect for:
- ✓ The Efficient Primary Residence: A study in spatial intelligence for a streamlined lifestyle.
- ✓ The Modern ADU: A striking and functional secondary dwelling with a voluminous interior.
- ✓ The Stylish Guest House: A clean and efficient sanctuary that maximizes its compact footprint.
