Alchemy

Alchemy Architects ADUs

Founded by Geoffrey Warner in 1992, Alchemy Architects is an architectural design firm focused on environmentally responsible, smaller residential home designs built using various prefab and modular techniques.

Alchemy’s residential home and ADU designs are based on their weeHouse® building block concept. weeHouse® modules can be used alone for smaller, 300 – 850 square foot dwellings (Alchemy’s 1x weeHouse®) or added together for larger layouts of various configurations (2x, 3x, or 4x weeHouse® designs). The weeHouse® series of homes is designed for primary homes, vacation homes, ADUs, or even multi-family projects.

The lightHouse series by Alchemy is specifically designed to be used as accessory dwelling units or ADUs. These homes are offered in a variety of standard sizes from S, M, L, XL, and 2X as follows:

• S (14′ x 22′ 310 sq ft)
• M (16′ x 24′ 380 sq ft)
• L (16′ x 30′ 480 sq ft)
• XL (16′ x 38′ 600 sq ft)
• 2X (24′ x 24′ 570 sq ft w/ tuck-under garage)

In addition to the weeHouse® and lightHouse series of homes, Alchemy also offers a panelized series of barn-modern style homes, the barnHouse series. The Small and Large standard models offer open, lofted living space with up to three bedrooms, two bathrooms, and a loft or second level. The barnHouse homes are assembled from 12″ high-efficiency SIPs (structural insulated panels) and designed to be economical to purchase, and live in, with total project costs estimated around $300 per square foot.

Alchemy coordinates all Alchemy projects alongside the homeowners. Depending on the location and series of the home purchased (weeHome, lightHome, or barnHome), the building process may involve a variety of prefabrication, modular or panelized techniques. Alchemy works with several prefab build factories in Utah, California, and Washington.
