"Ofer and Bay Easy Construction are amazing. They are my go to company. Ofer is an honest person who will give you a great estimate. I have used them on several projects and will continue to use them in the future. He was able to solve a flooding problem in my garage. His team came in and moved the cabinets to ensure they could simulate where the water was coming in from. His team fixed the problem in a few days."

"I was very impressed with Bayside Builders from start to finish. They were always asking what we wanted before starting any part of the renovation because it's important that everyone is on the same page beforehand so they can deliver exactly what you're looking for. The contractors are very professional, punctual , show up every morning at 8 am sharp during summer months, have amazing attention to details and craftsmanship plus I'm really happy with how everything turned out-just perfect!"

Customers say: True professional

"We found McCormick home builders through Angie’s list. They were not one of our original contacts, but they contacted us and came out to give us a quote. Matteo was extremely helpful, informative, honest, and gave us reasonable realistic prices, and did not try to inflate the prices or pressure us in anyway. We felt very comfortable with him immediately. We felt like he was a member of the family that we could just talk to and ask questions he was very personable. He gave us his contact number in case we had other questions and he was always available when we needed him for any type of questions or concerns. Mateo‘s team did a beautiful job. They were fast. They were efficient. They cleaned up beautifully. They did a wonderful job. They were very considerate of our time our needs and our neighbors. They were an absolute pleasure to work with. I would highly recommend Matteo from McCormick home builders for any home building projects, and we will be calling him again in the future!"

"If you’re thinking about getting a new roof, definitely go with Build Atlas. I’m in my mid-20s and had no idea where to even start, but a neighbor recommended them and I’m so glad that they did! The whole team was super friendly, down-to-earth, and made the entire process way less stressful than I imagined. They showed up when they said they would, kept everything clean, and finished faster than I expected. Plus, the roof looks fantastic — it’s like my house got a facelift! It’s rare to find a company that’s this easy to work with!"

"We are very pleased with the work done through Streamline Renovators. Everything looks beautiful. The installer's punctuality and communication could have been better at times, but the final result was very good and the price was competitive to say the least."

Subcontractors questions, answered by experts

Universal design costs can be minimal when you add them during construction; however, adding universal design principles to existing homes can sometimes increase renovation costs. For example, a mid-grade bathroom remodel is estimated to cost around $30,000, while a standard universal design remodel can cost closer to $40,000. Adding accessible design components can include widening hallways ($500 to $2,000), curbless showers ($2,000 to $8,000), and widening doors ($400 to $800). Keep in mind that these increased costs can lead to higher resale values because universal homes may appeal to a wider variety of buyers.

Building designers charge between $2,000 and $50,000, depending on project scope, complexity, and customization.

It is technically possible to draw your own blueprints, but the process is extremely involved and really demands help from an expert. A professional architect has an understanding of design elements, interior design, the functionality of different rooms in a home, and how everything from furniture, outlets, and light switches should be laid out to serve you and your family best. Hiring an architect for blueprints can get expensive, but it’s the most responsible way to begin a new construction project. If you’re keen on DIYing, you could consider starting the process and then having a professional take over.

You likely need to hire an architect for your new house design and build, unless you have the design skills and experience with building regulations and standards needed to get your plans approved. If you are able to meet the design requirements, you can hire a draftsperson to create the blueprints for the builders to follow.

It usually takes around four to six months to build and install a modular home, although your timeline could go up to around eight months if there are delays in the manufacturing or permitting process. Heavy site preparation and foundation pouring can extend that timeline if you need them, as can customizations you want for your modular home. Your modular home company should be able to provide an estimate for the construction timeline before you sign any contracts or agree to any work.
