"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."

"I've been working with John and his sub contractors on this property since August of 2013, and they have been patient, responsive, and transparent throughout, especially appreciated when my property insurance had to get involved and they worked with them to get them details, quotes, and insight, as well as being a much-needed professional advocate that I never would have been able to accomplish on my own. I have no doubt that John's professionalism helped speed the process along.
When I realized I would have to switch contractors from my first GC, out of everyone I called, John was the only one who brought someone with him for a second opinion on his assumptions, and even sent additional subs out to ensure the accuracy of the quote. I have had nothing but great experiences with him and everyone he works with since.

"We originally hired Peter to do the design only. We selected him over other architects and are pleased with the design. He listened to our ideas and provided very practical solutions and helped us with zoning variances. During the design phase, they added "and Builders" to their services. We selected Idea over a lower bid because of our good experience with Peter. The build is in progress and the sub-contractors are profession and do quality work. I will update this report when the build portion is complete."

"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

A carriage house is a freestanding building, while a townhouse is connected to other units. A townhouse is a full single-family home and typically shares a parcel of land with other connected homes. A carriage house is rarely used as the sole single-family home on a property and is most often an additional building sharing property with a traditional single-family home. 

The term “cottage” is subjective, so there’s no rigid definition, but it generally refers to a small home with simple and purposeful architecture that embraces nature and focuses on charm over everything else. Cottages are typically 1 or 1 1/2-stories tall, usually with gabled roofs, and are built out of natural materials that help make the structure a part of the surrounding nature rather than something that stands out from it. A big part of what makes a cottage a cottage is the decor, which includes natural materials from the nearby area.

No, a structural engineer is not the same as a builder. A structural engineer is an expert in all things related to the structural integrity of a building. The structural engineer is responsible for calculating the correct materials in terms of load-bearing capacity and overall structural safety. Structural engineers do not perform the actual building of the house or other structures. Rather, the builder executes the plans and designs specified by the structural engineer.

Yes, you can finance new construction, though the process often requires a different type of loan than one for an existing property. There are several financing options available:

  • Construction-to-Permanent Loan: This is a common option where a single loan covers the building costs and then converts into a traditional mortgage once construction is complete and you move in.

  • Construction Loan (Stand-Alone): This type of loan provides funding only for the duration of the construction project. Once the house is built, you will need to pay the loan in full, typically by securing a separate, standard mortgage.

  • Builder Financing: Some custom homebuilders offer their own financing options, which may only require a down payment to begin the building process.

  • Bridge Loan: This can be a useful short-term loan to fund your new construction while you are in the process of selling your old home.

  • Home Equity Options: If you are building a second home, you might be able to use a home equity line of credit (HELOC) or a cash-out refinance on your current property.

It's also important to be aware that some lenders may have restrictions on financing for DIY house builds, so be sure to verify that you can secure financing before starting your project.
