One-Five Design Co. creates practical building plans and reference guides for small residential projects, with a focus on clarity, efficiency, and real-world buildability.

The work is rooted in the belief that good buildings begin with good planning. Rather than offering one-off designs or highly customized drawings, One-Five Design Co. develops complete, well-considered plans intended to be used as part of a thoughtful building process—whether the project is owner-built or constructed with local professionals.

The plans emphasize:

• Clear structure and straightforward construction logic
• Efficient use of space, materials, and energy
• Drawings prepared to industry standards and suitable for permit review
• Designs that balance proportion, durability, and long-term use

Alongside the plans, One-Five Design Co. provides building guides designed to help owners understand how drawings are intended to be read, how costs and tradeoffs emerge, and how the overall process fits together before construction begins.

This approach is intended to reduce uncertainty, prevent common missteps, and support projects that are built with intention rather than haste.

The goal is not to simplify building—but to make the process easier to understand before it begins.
