BLB Design/Build, an Amesbury, Massachusetts-based design-build firm, has announced it is now accepting projects in Southern New Hampshire and the Seacoast region, including Portsmouth and Exeter. The expansion brings the company's integrated design and construction services to homeowners who have historically had fewer options for coordinated remodeling services in the area.
What sets BLB Design/Build apart in the design build remodeling Southern NH market is its single-team approach. Rather than handing a project off between a designer, a general contractor, and subcontractors who may have never worked together, BLB Design/Build keeps everything in-house. The same team that draws up the plans pulls the permits and completes the build. Homeowners deal with one point of contact throughout, which reduces miscommunication and keeps timelines and budgets easier to manage.
This structure is especially relevant for complex projects like home additions in Southern NH, where design decisions made early in the process directly affect structural requirements, permitting timelines, and final costs. When the designer and builder are the same team, those decisions get resolved before a shovel hits the ground.
Among the services BLB Design/Build now offers to Southern NH and Seacoast homeowners, home additions represent a core part of the firm's work. These projects include traditional room additions, in-law suites, and accessory dwelling units (ADUs) — spaces that give families more room without requiring a 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 actually be used before finalizing any plans. The result is an addition that fits the home structurally and fits the household functionally. Beyond additions, the firm handles kitchen remodels, bathroom renovations, and whole-home projects.
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 the 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 firm's expansion into communities like Portsmouth and Exeter positions it to serve a region where homeowners often undertake additions or renovations on older housing stock that requires 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 the design phase through the final walk-through.
