Design-build additions with commercial-grade project management
Why Choose Us
The Bradford Difference
Most contractors disappear after the final payment. We don't. Here's what makes our design-build approach to home additions different. Learn more about us.
Daily Photo Documentation
Every day, you receive timestamped photos showing progress on your addition. No guessing what's happening on site - complete transparency from foundation to final walkthrough.
Commercial-Grade Project Management
We bring professional project management from $500M+ commercial builds to your home. Clear schedules, documented milestones, and accountable execution every step of the way.
Transparent Pricing
We provide detailed scopes with clear pricing upfront. Any changes during construction go through a documented change-order process - you approve costs in writing before we proceed.
Lifetime Support
Through Bradford Home Services, we provide ongoing maintenance and support after your addition is complete. We don't disappear - we're here for the long term.
Our Services
Home Addition Services We Provide
From second-story additions to garage expansions and in-law suites, we handle every aspect of your project - design, permitting, structural engineering, and construction. View our full range of services.
Second-Story Additions
Add bedrooms, bathrooms, or dedicated office space by building up instead of out. We handle structural analysis, foundation reinforcement, and seamless integration with your existing roof and exterior.
Garage Additions & Conversions
Expand your garage for additional vehicles or storage, or convert existing garage space into livable square footage with proper insulation, HVAC, and electrical.
In-Law Suites & ADUs
Create accessible, comfortable living spaces for aging parents or adult children. We navigate Massachusetts ADU regulations, accessibility requirements, and utility connections.
Bump-Outs & Room Extensions
Expand kitchens, dining rooms, or living areas without the cost of a full addition. Bump-outs provide strategic square footage gains with minimal disruption.
Whole-Home Additions
Major expansions that transform your home's footprint and functionality. Comprehensive planning includes structural engineering, mechanical system upgrades, and aesthetic integration. Often combined with a whole-home renovation.
Sunrooms & Four-Season Rooms
Light-filled additions with proper insulation, heating, and foundation work. Designed for year-round use in New England's changing seasons.
Planning more than an addition?
We also deliver custom home builds, kitchen remodels, and bathroom remodels - often as part of the same project. One team, one timeline, one point of contact.

Common Questions
Home Addition FAQs
Common questions about home additions, permitting, timelines, and costs in Massachusetts.
Home addition costs in Massachusetts typically range from $200 to $500+ per square foot depending on the scope, complexity, and finishes. A standard 400-square-foot addition might range from $80,000 to $200,000. Second-story additions, structural complexities, and high-end finishes increase costs. We provide detailed, transparent estimates during the consultation phase so you understand the full investment before committing.
Yes, all home additions require building permits. This includes zoning approval, building permits for structural work, and inspections for electrical, plumbing, and mechanical systems. We manage the entire permitting process including applications, plan submissions, and coordinating inspections so you don't have to navigate local building departments.
Project timelines vary based on size, scope, and complexity. During your consultation, we'll assess your specific project and provide a realistic timeline. Our commercial-grade project management systems help us maintain schedules and keep you informed of progress through daily documentation.
Most homeowners stay in their homes during addition construction. We create temporary barriers, maintain safe access paths, and schedule noisy work during reasonable hours. For major whole-home additions or second-story projects, there may be brief periods where utilities are interrupted, but we plan these carefully and provide advance notice. Our daily updates keep you informed of any upcoming disruptions.
Design-build means one team handles architectural design, engineering, and construction under a single contract. This eliminates the finger-pointing and miscommunication that happens when architects and builders work separately. Changes are faster, decisions are clearer, and you have one accountable partner from concept through completion. Traditional approaches require managing multiple contracts, coordinating between different companies, and navigating conflicts when design and construction don't align.
Yes. We design additions to integrate seamlessly with your home's existing architecture, rooflines, siding, and windows. This includes matching materials, trim details, and proportions so the addition looks original to the house. Our design team evaluates your home's character during the consultation phase and creates plans that enhance - not clash with - the existing structure.
Unlike typical contractors who disappear after final payment, we provide ongoing support through Bradford Home Services. This includes warranty follow-through, seasonal maintenance, and access to our team for any issues that arise. Because we already know your home, you're not starting over with a stranger when something needs attention.
Yes. All our addition projects include professional structural engineering to ensure safety and code compliance. This covers foundation analysis, load-bearing calculations, beam sizing, and integration with existing framing. For second-story additions, we evaluate whether your current foundation can support the additional weight or if reinforcement is needed. Structural plans are submitted with permit applications and verified through building inspections.
All changes go through a documented change-order process. If you want to upgrade materials, modify layouts, or add features during construction, we provide a written change order with the cost impact and timeline adjustment before proceeding. This prevents surprise bills and keeps the budget transparent. You approve every change in writing before we execute it.
Three things: daily photo documentation so you always know what's happening, commercial-grade project management that brings professional systems to residential work, and lifetime support through Bradford Home Services after the project is complete. We're Massachusetts HIC licensed (#201908), fully insured, and committed to transparent pricing with documented change orders.
