"It was great to work with Icon Builders to building our dream home. They went out of their way to accommodate the completion of our home build in time for school. Their response times are great and the staff is truly personable. It was great working with Jenna, Natalia, Joe, Scott, Shawna and Charlie. I will recommend Icon to anyone looking to build a custom home."

"I can't say enough about A P Builders and how absolutely wonderful they have been from start to finish. We completely gutted and remodeled our home and Angelo was upfront, honest, timely, and everything that was contracted was done to perfection. We had crew there every day from start to finish. He started on time and finished on time. Any change orders were handled professionally and solutions were found for any unforeseen challenges due to the age of my home. I highly recommend AP Builders for any of your home improvement needs."

"We actually had 4 major renovations - the basement finished, master bath remodel, kitchen remodel, and garage finished. Started the projects on 6/1/2022 and finished on 7/31/2022 - amazing time frame. Projects flowed smoothly, attention to detail was awesome. All of our questions and concerns were addressed to give us the utmost comfort level to choose Aaron/Clean Edge to handle our remodeling projects. Carmella did an awesome job in keeping us updated on when to expect contractors to be in the home. There is not one thing that I would have changed in what was done, but believe me, we did change things as we moved along in the projects... added a 1/2 bath in the basement and changed the kitchen and basement counter choices. Aaron and crew were amazing to work with. I would highly recommend them and were very happy to work with them."

Overall we are very satisfied with the work. It didn't take long for John to review our initial drawings and issue a quote and get the job scheduled. Between the time we scheduled the job and when work actually began we made some changes to the plans and John and his guys were able to accommodate. They also found some relatively shoddy workmanship from the builders of our townhome and did their best to point out areas that needed attention. The initial demo and framing went very well and moved quickly. After demo and framing there were times when communication wasn't the best and there were many days when work wasn't done and we weren't kept up to date on the schedule, which I understand is very typical for this type of job and not unique to John and his guys. I do wish he would have used a different electrician. He was pretty messy and rarely showed up and we still have some minor flickering with the lights in our master bedroom. The finishes are excellent and John's tile work was very good. The custom vanity they built for our master is excellent and it's fits perfectly. The shower glass is just what we wanted. Overall I was vey happy with the outcome despite some minor frustrations with the process. I would definitely call John again for other major jobs.

"We started working with IDEA back in the fall of 2010 for designs for a remodel/addition to our 1950's Cape Cod.  The designs were done by one of the original partners of the firm and we could not have been more pleased.  He really took into account our desire to maintain the overall feel of the house and the charm as well as creative ways to re-purpose existing space.
Construction on the house started in April of 2011 and was originally supposed to take 6 months.  We ended up being out of our house for 7 months but most of the delays were due to weather issues at the very beginning of the project.  Also, mid-way through the project, Peter (the architect who did our drawings) left the company to move out of the country.  Marty and Angela did scramble at first trying to pick up the pieces in Peter's absence but eventually, things sorted themselves out and we honestly have nothing but good things to say about them!  They were incredibly responsive to our requests and concerns, Angela provided excellent guidance with design, color, style etc. on decisions that we easily could have been overwhelmed with.  She has a wonderful taste level!  Any time we had issues with how construction was progressing, Marty quickly responded, met with us and made sure things were fixed to our satisfaction.  He is also one of the genuinely nicest people we have ever met!  
It's been several months now since the project has been completed and we could not be more pleased.  Any kind of construction/remodeling on your house is stressful but in retrospect, Marty and Angela were great to work with and we would definitely recommend them, and IDEA to anyone considering a remodel or addition.  They were great!"

"The service was top notch and would definitely use the service again. Contractor was very professional and always honest with the situation. Price was a bit higher than I initially budgeted for but the quality of work more than made up for the higher cost. I was very pleased with the whole job being completed in 3 weeks when it was initially estimated for a 4 week process. Any future home construction jobs in the future, I will immediately call this contractor first.

Custom Home Builders FAQs, answered by experts

Ranch and colonial-style homes are often the most affordable to build. They have a common layout with available designs that are easy to adjust in simple ways without having to spend too much on a structural engineer or architect. Both types of homes' symmetry, simple roofs, and often one or two-story plans mean they often fall in the $150 to $200 square-foot range, putting them right around average.

An A-frame home can be cheaper to build than a traditional house, but that is not always a given. Prices can be fairly similar in some cases, depending on the location, design, and necessary site preparation. Costs for an A-frame typically run between $100 to $200 per square foot, which is comparable to the cost of a traditional home. The cost of an A-frame can come in under those numbers if you opt for a prefabricated kit.

Building a house without blueprints is not advised. It will prevent you from obtaining necessary building permits and meeting building codes and is likely to result in shoddy construction and unsafe living conditions. Detailed blueprints ensure that a house is built to exact specifications and is constructed safely and structurally stable.

In most states, you can build an in-law suite on your property as long as you follow local building codes. However, it's important that you have enough space on your property to accommodate the new structure. A functional in-law suite in your backyard will require between 300 and 800 square feet of space.

Modular homes are a type of prefab home. Specifically, manufacturers first build modular homes in sections and then deliver them to the job site. The modules, or sections, are usually at least 70% finished before they arrive on your property.

In comparison, prefab homes arrive in panels or segments, and workers assemble them on-site. Generally speaking, modular homes tend to be more durable, and their consistent construction standards may mean you’ll have an easier time getting conventional home loans.
