Home Addition Plans — Southern NH & Northern MA

Need more living space? I create custom addition plans that blend seamlessly with your existing home—whether you are adding an in-law suite, expanding a kitchen, building a garage, or planning a complex second-story extension.

As a draftsman with a 40-year background in framing carpentry, I specialize in solving the structural puzzles that come with remodeling. I don’t just design the new rooms; I make sure the new rooflines tie cleanly into your old roof system, the foundation additions are engineered correctly, and the entire layout is optimized for a smooth construction process.

Common addition types I design:

• In-law suite and apartment additions (High-demand multi-generational spaces)

• Garage additions (Attached, detached, and bonus rooms over garages)

• Kitchen and great room expansions (Including vaulted ceilings and custom fireplaces)

• Second-story additions and full home extensions

• Bedroom, bathroom, and mudroom expansions

What’s Included in Your Permit-Ready Plans: To get a building permit in New Hampshire or Massachusetts, your town requires specific details. I deliver complete construction documents that include:

• Detailed floor plans showing existing vs. new layouts

• Full exterior elevations to show how the addition matches your current home

• Precise structural foundation and conventional wood-framing details

• Compliance with local NH and MA building codes

Accurate As-Built Measuring The most critical part of drawing an addition is mapping out the current house correctly. I specialize in creating accurate “as-built” layouts of your existing home. This ensures your new SoftPlan blueprints line up properly with your home’s real-world dimensions, preventing costly framing surprises on-site.
