BLB Design/Build, an Amesbury, Massachusetts-based design-build firm, has announced its expansion into Southern New Hampshire and the Seacoast region, including Portsmouth and Exeter. The move brings the company's integrated, single-team remodeling approach to homeowners who previously had limited options for coordinated design-through-construction services in the area.
What distinguishes BLB Design/Build in the design build remodeling Southern NH market is its in-house team structure. Rather than passing a project between a designer, general contractor, and subcontractors who may not have collaborated before, BLB Design/Build keeps all aspects in-house. The same team that creates the plans also obtains permits and completes construction. Homeowners interact with a single point of contact throughout, which minimizes miscommunication and makes timelines and budgets easier to manage.
This structure is particularly beneficial for complex projects like home additions in Southern NH, where early design decisions impact structural requirements, permitting timelines, and final costs. When the designer and builder are the same team, these decisions are resolved before construction begins.
Home additions are a primary focus for BLB Design/Build. The firm handles traditional room additions, in-law suites, and accessory dwelling units (ADUs), providing families with more space 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, resulting in an addition that fits both structurally and functionally. Beyond additions, the firm also offers kitchen remodels, bathroom renovations, and whole-home projects.
BLB Design/Build brings a documented track record to its expansion into Seacoast NH remodeling, with a 5.0 Google rating across more than 20 reviews from its Amesbury-area work. The reviews consistently highlight 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 BLB Design/Build to serve a region where homeowners often undertake additions or renovations on older housing stock, requiring careful planning around existing structure, local code requirements, and site conditions. The firm's integrated team manages all of that within a single coordinated workflow, keeping each project organized from design through final walk-through.
