Lumara is a Massachusetts ADU builder with two starting footprints and a property-first process. We help you connect the design you want with the site work, plans, approvals and construction your address needs.
For aging in place, we discuss entry access, circulation and bathroom needs early. Accessibility features are developed for the household and property through design.

From your address to your ADU
A clear way forward.
Review the property.
Start with your address and who the home is for. Walk the property with Lumara, or begin by Phone/Zoom. Review placement, access, utilities and major site questions.
Resolve what matters.
Where needed, define survey, septic, wetland or other investigations before moving further. Receive a written recommendation and agree on fees before authorizing work.
Develop the plans.
Refine the home and coordinate architectural, structural and applicable site documents, with a permitting path specific to your property.
Build with clarity.
Agree on the construction scope, price, responsibilities and terms. Coordinate the work with required approvals, utilities and inspections.
Massachusetts properties need local planning
Designed for the home.
Planned for the land.
The right ADU is about more than a floor plan.
Usable yard, privacy, slopes, ledge, drainage, construction access and utility distances shape what is practical. Septic capacity and local review can also change the scope.
We bring those questions into the conversation early, before the project moves into full design and construction.

A few useful answers.
What does a Massachusetts ADU builder coordinate?
The home must work with the property. Lumara’s process connects model selection, site questions, plans and engineering, permitting and a defined construction scope. The written agreements identify the services, costs and responsibilities for your project.
Is the starting price the complete installed cost?
No. Lumara 320 starts at $209,000 and Lumara 640 at $373,000 for standard home construction. Foundation, external utilities, site work, project-specific installation, plans, engineering and permits are additional. We assess those items for your address and confirm scope and price in writing.
Can you help me plan a home for an aging parent?
Yes. Begin with how your parent lives today and what may matter over time. Entry access, circulation and bathroom design should be considered early. Final accessibility features depend on the site, selected layout and agreed design scope.
How long will an ADU take?
The schedule depends on investigations, design, local review, utility work, site conditions and the construction scope. We develop the project path as those details become clear rather than promise one timeline for every property.
What happens after I request a property review?
Raphael will text or call, based on your contact preference, to arrange your selected onsite or Phone/Zoom review. The initial review is at no cost. Your appointment is booked once you agree on a date and time; submitting a request does not confirm property eligibility or permit approval.
