BUILT AROUND YOUR HOME
A seamless addition starts with the connection.
An addition should improve how your whole home works. We discuss circulation, daylight, rooflines, materials, and the transition between existing rooms and new space. Foundation, framing, utilities, and existing conditions shape the final scope.
MASSACHUSETTS COST GUIDE / EARLY PLANNING
What might an addition cost?
A published Massachusetts builder guide lists $150–$350+ per square foot, with a 400 sq ft example at $60,000–$140,000. These are Greater Boston reference figures, not SR USA quotes or guaranteed Cape Cod prices.

A smaller extension to an existing room.
SINGLE-STORY ROOM

Scope, foundation, roof connection, mechanical systems, exterior matching, and finishes affect cost. Confirm inclusions, site work, utilities, design, and permits in a written proposal. Martha’s Vineyard and Nantucket need separate island pricing. Read the published Massachusetts cost guide ↗
CONCEPT DRAWINGS — NOT FOR CONSTRUCTION. No site eligibility, permit approval, structural suitability, or final dimensions are implied. These examples are not represented as completed projects. Your actual plans must be developed for your property.
A CONSIDERED PROCESS
Clear steps. Better decisions.
01
Tell us your vision
Share the property, the way you want to use the space, your priorities, and your existing plans.
02
Review the home
Discuss the structure, access, utilities, and the site conditions that influence your project.
03
Define the scope
Coordinate design questions, materials, responsibilities, and the construction estimate.
04
Build with clarity
Move forward with an agreed scope and clear conversations about decisions and changes.
BEFORE WE BEGIN
Your questions, answered.
Can you work from my architect’s plans?
Bring your architectural drawings, survey, and any existing reports. We can review the proposed construction scope with you and identify questions that need coordination with your designer.
Are these actual approved construction plans?
No. These are illustrative design studies created to compare layouts. They are not approved plans or drawings of completed SR USA Construction projects. A build requires property-specific architectural and structural design and the applicable reviews.
How do I get a project estimate?
Send your property address, photos, intended use, rooms needed, and any plans you already have through our estimate form. Cost and timing depend on the property, scope, approvals, and selected materials.
What areas do you serve?
We serve Massachusetts homeowners from Cape Cod to Boston and Worcester. Contact us with your property address to discuss your project.
