"I can't say enough about John, Gary, and the team at Busy Bee Construction. They took on a big project transforming my horror of an overly-large primary bathroom into a beautiful, new bathroom plus an additional study. They were clear, communicative, and knowledgeable, and they did exceptional work at a very fair price. I would absolutely work with them again (and definitely will!). These guys are the real deal."

Ayotte Home Improvements is a fully licensed and insured remodeling/construction company. We offer free estimates and years of experience.Take a look at our website for some of our past projects.
"We were very happy with Bob Ayotte and his team and would hire them again. We hired Ayotte Home Improvements to remodel the two and a half bathrooms in our ~25-year old house. In the two full bathrooms they stripped everything down to the studs, replaced vanity, counter tops, sinks, and toilets, and installed tile in the new bath/showers. They started demolition in January and received final sign-off from the local building inspector in April. Bob’s team was very respectful of the rest of our house, doing everything within their power to reduce the spread of dust and dirt from the construction areas. All work done was high quality. Of exceptional note was the tile work. Brian at Nashua Tile was extremely helpful in choosing the right style and colors for the bath/shower tiles to coordinate with our counter tops and overall color scheme. Kirk, who installed the tiles did a meticulous job and the result added a real visual “pop” to the two full bathrooms. As with any project of this scope, there were issues to be transcended. When the newly installed shower plumbing leaked, Bob recalled his plumber to address the issue through the hallway wall and arranged for re-plastering and painting. Similarly, when the wrong toilet and fixtures were installed and the faucet leaked, the plumber fixed the issue with little to no impact to the overall schedule. Bob’s allowances were reasonable, allowing for “better” on a scale of “good, better, best”. Our selections, which included some “best” toilets and shower fixtures, came in very close to Bob’s original allowances. Bob’s preferred suppliers were easy to work with, although those with 9 to 5 jobs may find their scarcity of evening and weekend hours problematic. Overall, a great experience!"

Guest house building services FAQs
In most states, yes—you can build a guest house, but every city or county sets its own zoning rules and building codes. Before breaking ground, check local ordinances, confirm lot setbacks, and secure the right permits. A local contractor or design-build firm can walk you through the paperwork and site requirements so your project starts on solid legal footing.
Yes—homeowners often tap a few different financing tools. A home-equity line of credit (HELOC) lets you borrow against your equity as you need funds. If you prefer a lump sum tied directly to the project, a short-term construction loan can roll into a second mortgage once the build is complete. Cash-out refinancing is another option: you replace your current mortgage with a larger one and use the difference to cover construction costs.
When you build a guest house, you’re creating a separate structure for hosting visitors without the full amenities needed for permanent living. An accessory dwelling unit, however, includes a complete kitchen and bathroom, meeting building codes for a long-term residence. This key difference makes an ADU ideal for long-term occupancy or rental income, adding enduring value to your property.
How many rooms you need depends on how you plan to use the space. Aim for one bedroom per every one or two occupants to make sure everyone has enough privacy and comfort. Added living and dining areas give you extra functionality, especially for rental use or long-term stays.
Most homeowners pick somewhere between 600 and 1,500 square feet to fit all the essentials. Make sure your design supports one to two occupants per bedroom and includes enough common areas for comfortable daily living. A well-proportioned layout boosts both functionality and property value.
No—a guest house isn’t just a bump-out on your main home. A bump-out is a small extension within an existing room for extra seating or storage. In contrast, you build a guest house as a standalone building with its own foundation and amenities, giving you a fully separate living area that can boost your property’s versatility and value.
