These homes are: - Sustainably focused and structurally optimized. - Designed for lower design-related costs and shorter timelines than a fully custom home. - Created to be modern, energy-efficient, and high-performing, while maintaining strong design character. Because the core plans are already established, pre-designed homes usually involve fewer decisions and a more streamlined process. Pre-designed home collections Sustainable 9 and Unfold have created several design lines, including: - Scandi – Minimalist, functional designs with clean lines and simplicity. The Scandi line includes multiple layouts with different square footages and lot types, including multifamily rowhome configurations. - West Coast – Modern waterfront-inspired homes with expansive glass, open floor plans, and strong indoor–outdoor connections, balancing simplicity, elegance, and livability. - Mountain – Designs oriented around the natural landscape, often with separate wings for private and public spaces, strong connections to views, and warm, natural materials. Typical timelines (from the website FAQ) Timeframes vary by project, but the website notes the following typical ranges: - Design phase - Pre-designed home: approximately 2–4 months. - Custom home: approximately 4–8 months. - Permitting and loan (for both pre-designed and custom homes): typically 1–2 months. - Construction phase - Pre-designed home: typically 6–10 months. - Fully custom home: typically 10–14 months, depending on complexity and level of personalization.
