Garage and detached structure construction for homes in Charlestown, New Hampshire.
You park outside because your home in Charlestown does not have a garage, or you store tools, equipment, and seasonal items in a basement that floods or a shed that sags. A detached garage or accessory structure gives you covered parking, organized storage, and workshop space that keeps vehicles and belongings out of the weather. If your property has room for a separate building, this option adds value and function without altering your home's footprint.
T2B Carpentry, LLC builds single and multi-bay garages, workshops, storage sheds, and accessory structures on residential properties. The process includes site preparation, pouring a concrete slab, framing walls and roof, installing doors and windows, and siding the exterior with materials that match or complement your home. You choose the size, door configuration, and interior layout based on what you plan to store or build inside.

Build Storage and Workshop Space That Lasts
What Gets Built From Slab to Roof
Construction in Charlestown starts with clearing and leveling the site, then forming and pouring a concrete slab with footings that extend below frost line. T2B Carpentry, LLC frames the walls with studs sized for the span and load, installs roof trusses, and sheathes the structure with plywood or OSB before adding roofing and siding. Overhead doors, entry doors, and windows get installed once the shell is weather-tight.
When construction finishes, you will have a dry, enclosed space with a level floor that supports vehicle weight and keeps moisture from reaching stored items. Overhead doors open smoothly without binding, and the roof sheds snow and rain without leaking. If you added electrical service, outlets and lighting are wired and ready to use.
The work includes site prep, slab, framing, roofing, siding, doors, and trim. It does not include electrical, insulation, or interior finish unless specified during planning. If you want a heated workshop or need plumbing for a utility sink, those systems get priced separately and installed before drywall goes up.
What size garage do I need for two vehicles?
A two-car garage is typically 20 by 20 feet minimum, but 24 by 24 feet gives you room to open doors, walk around vehicles, and store equipment along the walls. T2B Carpentry, LLC helps you size the structure based on what you plan to park or store inside.
How deep does the slab need to be?
The slab itself is usually four inches thick, but footings around the perimeter extend at least four feet below grade in Charlestown to sit below the frost line. This prevents the slab from cracking when the ground freezes and thaws.
When do I need a permit for a detached garage?
Most detached structures over a certain square footage require a building permit in New Hampshire, and some towns have setback rules that determine how close you can build to property lines. T2B Carpentry, LLC handles permit applications and confirms setbacks before construction begins.
What type of doors work best for a garage?
Insulated steel overhead doors resist dents and reduce heat loss if you plan to use the garage in winter. Wood doors offer a traditional look but require more maintenance, and aluminum doors work well for unheated storage buildings.
How long does it take to build a detached garage?
A single-bay garage typically takes two to three weeks from site prep to final inspection. Larger structures or those with electrical and interior finishes take longer depending on the scope and weather conditions in Charlestown.
T2B Carpentry, LLC builds garages and detached structures throughout Charlestown, and every project begins with a site visit to confirm grading, access, and utility locations before breaking ground. If you are ready to add covered parking or workshop space, get in touch to review your property and receive a written estimate.
