Our Design Delivery Approach

2. Site Concept / SD — starting from $900
Explore what could fit. Two site-placement or layout approaches for one ADU, preliminary floor-plan sketches and a concept massing study. Includes consultation and two consolidated revision rounds.
3. Developed Design — from $3,500
Refine your chosen concept. Dimensioned plans, elevations, a key section, preliminary materials and up to three AI-assisted presentation views checked against the drawings. Includes consultation and two consolidated revision rounds.
4. Construction Documents — from $6,500
Prepare for permit submittal. Architectural drawings, consultant integration and two architectural plan-check response rounds.
Each phase is priced separately. The report is an optional first step; consultation already included in a design phase is not charged again. Site complexity and project scope determine your final proposal.

Coordination & Project Support
Design coordination and construction-phase support: $150/hour. Permit coordination: from $2,000. Scope and caps agreed in advance; included coordination is not billed twice.
A few details before you begin
Reviews: Custom SD and DD each include two consolidated revision rounds on the agreed scheme. Developed Design includes two review meetings.
Site information: The Property Potential Report is a preliminary desktop review, with no measured drawings or confirmed feasibility. Concept sketches use supplied information and are not surveyed or permit-ready. Construction Documents require consultation, verified site information and a written scope.
Separate costs: Engineering, surveys, energy compliance, consultant and agency fees are separately scoped. Permit approval is not guaranteed.
Tailored proposals: Complex sites, conversions, two-story designs and multiple units need a project-specific quote.
Prefer a premade plan? Explore our coming-soon collection. DD purchases credit the architectural CD service for the same model and project after consultation; full credit terms are on the collection page.
