The Complete Architectural Set for The Datum.

The Design Intent

The Datum is a masterclass in spatial intelligence and modern form. Based on a perfect 21' x 21' square footprint, this 441 sq. ft. home is a study in efficiency, designed for those who value clean lines and a hyper-functional layout. The simple shed roof and large windows create a bright, voluminous interior that cleverly incorporates two distinct sleeping areas—a main-floor bedroom and an upper loft. The Datum is the definitive choice for a highly efficient primary residence, a modern ADU, or a stylish, compact guest house.

This is more than a set of drawings; it is the complete foundation for a life of intelligent, minimalist design.
