Custom Workshops & Accessory Structures in Southern New Hampshire
Need a dedicated space for projects, equipment, storage, hobbies, or something that doesn't quite fit inside your home or garage?
DeSalvo Builders designs and builds custom workshops and accessory structures for homeowners throughout Southern New Hampshire. We plan each building around your property, intended use, preferred layout, and long-term needs.
Whether you're looking for a dedicated workshop, equipment building, hobby space, storage structure, or multi-purpose building, we'll help you create a structure designed specifically for how you want to use it.
A Custom Structure Designed Around Your Needs
We design your project around your property, priorities, and the way you plan to use the space. We have designed and built custom structures for a variety of purposes, including:
Dedicated workshop space
Tool and equipment storage
Lawn and garden storage
Recreational vehicle storage
Hobby and craft workspace
Seasonal item storage
Project and fabrication space
Upper-level storage space
Machinery and equipment space
Multipurpose work and storage space
Custom Design & Construction vs. Prefab Buildings
Prefab and packaged buildings can be practical when your needs match a standardized design. But if you need more space, greater flexibility, specific features, or a structure designed to complement your property, custom construction may be a better fit.
​
A custom workshop or accessory structure gives you greater flexibility when making decisions about:
Building dimensions
Building height
Door size and placement
Window placement
Roof configuration
Exterior materials
Interior layout
Storage and work areas
Electrical needs
Lighting options
Upper-level storage
Future space needs
Instead of adapting your plans to a packaged building, we design the structure around your specific needs.

What Should You Consider When Planning a Workshop or Accessory Structure?
Property Details
One of the first things we look at is where the structure will sit on your property and how you'll access it.
Grade, setbacks, driveway access, drainage, utilities, nearby buildings, property lines, and the size of vehicles or equipment entering the structure can all influence the final design.
Thinking through these details early can help you select the right location, footprint, and configuration for your new building.
How You'll Use It
Next, we look closely at what you actually plan to do inside the space.
A woodworking workshop may have very different requirements than a building used for equipment repair, vehicle storage, crafts, fabrication, or general household storage.
You may need more natural light, additional electrical capacity, larger doors, durable interior surfaces, insulation, dedicated work zones, built-in storage, or room for specialized equipment.
By understanding how you'll use the building today—and how your needs may evolve over time—we can help create a space that remains practical for years to come.
Custom Workshops & Accessory Structures FAQs
In many New Hampshire communities, yes. Permit requirements vary by size, location, intended use, foundation, electrical work, plumbing, and other project details.
Local zoning rules may also regulate setbacks, building height, lot coverage, and the number or type of accessory structures allowed on a property.
Do I need a permit to build a workshop or accessory structure in NH?
DeSalvo Builders can construct a range of custom accessory structures depending on your property and needs, including workshops, equipment buildings, storage structures, hobby buildings, and multi-purpose spaces.
Because each project is custom-built, you can design your structure around a specific use rather than a predetermined package.
What types of accessory structures does DeSalvo Builders build?
Yes. Depending on the project, a workshop can include insulation and heating provisions so you can use the space more comfortably year-round.
Your intended use will help determine the appropriate level of insulation, ventilation, electrical service, and interior finish.
Can you build a heated or insulated workshop?
Yes. You can incorporate electrical service based on how you plan to use your building, including general lighting, outlets, dedicated circuits, equipment power, exterior lighting, and other project-specific needs.
Can a workshop include electricity and additional lighting?
Depending on the design, property, and local requirements, yes. Loft or upper-level space can provide additional storage or other usable space.
Consider the intended use, access, structural requirements, and applicable local regulations during planning.
Can you build an accessory structure with a loft or second floor?
Yes. We can plan door sizes, ceiling heights, building dimensions, interior clearances, and access around the equipment or vehicles you need to accommodate.
Can you build a structure large enough for equipment or recreational vehicles?
Yes. We can coordinate exterior materials, rooflines, siding, trim, windows, doors, and other architectural details so the new structure complements your home and property.
Can you match my new workshop or accessory structure to my house?
No. DeSalvo Builders specializes in custom-built structures, not standard prefab building designs or packaged workshop kits.
Do you build prefab sheds or workshop kits?
Pricing varies significantly based on size, intended use, site conditions, foundation requirements, roof configuration, exterior materials, windows and doors, electrical work, insulation, interior layout, storage features, and level of finish.
