Westbrook Contracting LLC offers the highest level of professionalism and quality renovations Westchester County. We strive to meet our residential and commercial clients’ individual needs and do not cut corners. Dave, the owner, is on the jobsite from the first consultation through the close of the project to ensure his high standards. Thank you for considering Westbrook Contracting LLC and we look forward to impressing you!

"We hired Dave last year for a major remodeling project and were incredibly pleased with the result. His approach of bringing on his crew to review the plans on site led to a very accurate estimate which minimized surprises. When we started out he said he'd have people working on site 5-6 days a week and that was absolutely true - work was constantly progressing and he was in constant communication with us each week to lay out the plan and what to expect. Every day we love our new home more!"

They were so cordial -- knowing it was our only full bath, they worked quickly so we could get our kids in a tub again! This was much appreciated. The bathroom came out better than we even expected. I would redo my bathroom again with them in a heartbeat ... but I don't think we'll have to for a long time!!"

"We were very pleased with the job performed. Helio's team expanded and renovated our small master bathroom. We took out a large closet and converted it into our shower. Once started, they worked quickly and efficiently. We did have a few small hiccups, namely using our garage to cut tiles and mix thinset, which created an exorbitant amount of dust coating my tools, bikes, and anything else that was stored in the garage. We also had an issue with the cleanliness of the home after some of the workers left, however, after we brought it to Helio's attention, he made sure to tell the team to do a better job moving forward. Contract was a little confusing, so I would encourage many questions to clarify things ahead of time such as timeline for selecting certain items, confirming when the next payments are due etc. All in all, we're pleased with the project and how it turned out."

FAQs for guest house building service projects in Hartsdale, NY

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.
