BLB Design/Build, a design-build remodeling firm based in Amesbury, Massachusetts, has announced its expansion into Southern New Hampshire and the Seacoast region, including Portsmouth and Exeter. The move brings the company's integrated design-through-construction services to homeowners who have historically had limited options for coordinated remodeling in the area.
What distinguishes BLB Design/Build in the design build remodeling Southern NH market is its single-team approach. Instead of handing a project off between a designer, a general contractor, and subcontractors who may not have worked together, BLB Design/Build keeps everything in-house. The same team that draws up the plans pulls permits and completes the build. Homeowners interact with one point of contact throughout, reducing miscommunication and making timelines and budgets easier to manage.
This structure is particularly beneficial for complex projects like home additions in Southern NH, where early design decisions directly affect structural requirements, permitting timelines, and final costs. When the designer and builder are the same team, those decisions are resolved before construction begins.
Home additions are a primary focus of the firm's work. These projects include traditional room additions, in-law suites, and accessory dwelling units (ADUs) — spaces that provide families more room without the need to move. In-law suites and ADUs have become increasingly practical for multigenerational households. BLB Design/Build approaches each project individually, working with homeowners to understand how the space will be used before finalizing plans, ensuring the addition fits both structurally and functionally.
Beyond additions, the firm handles kitchen remodels, bathroom renovations, and whole-home projects for homeowners looking to update or reconfigure existing space.
BLB Design/Build carries a 5.0 Google rating across more than 20 reviews, a record built through its Amesbury-area work before this expansion into Seacoast NH remodeling. The reviews reflect consistent feedback around transparency, responsiveness, and quality of finished work.
"We built our reputation in Amesbury and the Merrimack Valley by being straightforward with homeowners about what a project actually involves — the timeline, the process, and the costs," said Ben Becker of BLB Design/Build. "Bringing that same approach to Southern NH and the Seacoast just made sense. Homeowners there deserve the same level of clarity and coordination."
The expansion into communities like Portsmouth and Exeter positions the firm to serve a region where homeowners often undertake additions or renovations on older housing stock that require careful planning around existing structure, local code requirements, and site conditions. BLB Design/Build's integrated team handles all of that within a single coordinated workflow, keeping each project organized from design through final walk-through.
