"I reached out to Liam to to possibly hire him to remodel two bathrooms for me. He came over to look at them and sent me an estimate. There were a few items we had discussed that were wrong on the estimate, and there were also a few new (minor) items we hadn’t discussed I wanted to add into scope, so I set up a follow up phone call with Liam. While on the phone with Liam, I had asked if he was licensed as a Construction Supervisor, which I read on Mass.gov was a requirement for my project scope. Liam said he was and when I asked for him to provide his license # when he sends me the revised estimate, he agreed to do so. (For context behind my request, Mass.gov had only showed his HIC license but not a CS license, and the phone rep I had spoken with also confirmed he was not licensed a CS. But I wanted to give Liam the benefit of the doubt…perhaps the license was not listed under his name, but maybe a partner name). The morning after our phone convo, I received this text from Liam: “Good morning, After speaking with you yesterday morning I've decided I do not want to do the project for you, I wish you all the best and finding another contractor. But I'm clearly not interested.” Huh? What the heck is this about? Since Liam didn’t give me the reason why he “clearly wasn’t interested” and when I responded to ask, I found he had blocked me from contacting him. I strongly caution anyone considering Liam to hire. This experience leaves me to believe he is not an honest, trustworthy, or legally qualified professional. He most surely does not have the CS license he claimed he has and was forced to bail on the project since he knew he couldn’t back up that claim with a license #. Liam evidently had no respect for me as a person. If he did he would have given me the common courtesy of the reason for his sudden loss of interest (or leave me the ability to respond to him to ask). I feel I dodged a bullet by doing some basic due diligence before hiring him (as I have done for every contractor I have hired for my projects in my 20+ years of owning a a home.) I strongly suggest that you think twice before contacting Liam for work to be done. Is this how YOU want to be treated? Is this someone you want to entrust your time and hard earned money to?"

We focus on all kind of projects, big or small. We do your traditional Landscaping such as cut grass, trim bushes/trees, pull weeds. We also work on bigger projects like creating new back or front yards and patios, and all kind of cement work. We work all year around and do our best to give the customers the best affordable price out there. We shovel during the winters and paint all year around, as well as much more.

"We do not recommend Hernanadez Landscaping. After at least 3 requests to for a written estimate, including the night before the project (we had to call for the arrival time), it was never provided. Red Flags! Jerry claims he sent it via the Angi app, and that he isn't given any personal contact information. However, he had previously asked for and gotten my personal email. When he first came to give an oral estimate, we liked the crew and agreed that they would install a walkway that matched the pavers of a connecting walkway, remove some trees and a brush pile, and clean the patio. When they arrived to start, we were told they didn't have the matching pavers. When we spoke with Jerry on the phone, it seemed he wasn't entirely sure which job was ours. At this point we cancelled the walkway project but asked him to do the other part of the job. The next thing we knew, the crew was packing up to leave. Jerry took no responsibility for the problems. One star is for the nice crew."

Homeowners and business owners rely on MACH for High Quality Masonry, Hardscaping and Landscaping Services, all aspects of creating a beautiful outdoor: patios, pavers, retaining walls, walkways, as well as lawn maintenance all year around.

"Mario and his crew did an incredible job on our very large project, encompassing a back patio, stairs down to stone walkway on side with retaining wall, and a total redo of front stairs, walkway and front porch. Mario and his crew are very skilled, professional, hard working, and timely. They always solicited input, were open to making adjustments to plan along the way, and when solicited for design advise offered up a wealth of knowledge! He also moved two 23 year old trees. Recommend highly!!"

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.
