Property-first planning
A floor plan is only real when the lot can support it.
Setbacks + usable yard
Test the building envelope, privacy, windows, outdoor access, and relationship to the main house.
Access + set
Review driveway width, turns, overhead conflicts, trees, crane conditions, and staging.
Routes + capacity
Trace electric, water, sewer or septic and identify upgrades or long runs early.
Code + permit path
Coordinate structural, energy, life-safety, zoning, and local submission requirements.
Before full plans
Start with a model direction. Refine after feasibility.
Lumara’s named models establish an architectural and dimensional starting point. Permit-ready plans, engineering, openings, foundation, utilities, and site details are developed for the selected property and scope.
What “starting plan” means
The diagrams and configurations are planning tools—not permit documents. Final square footage, dimensions, fenestration, room arrangement, structure, equipment, accessibility, and finish selections are confirmed through the project’s design and approval process.
Where cost enters
The Studio 160 currently starts at $120,000 plus site-specific installation. Other model and project pricing is confirmed after property fit, selected configuration, utilities, site work, and written scope are understood. Read the cost guide →
