"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."

Customers say: Super punctual

"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."

"Shawn and his team made the whole process so easy! They got the most out of my insurance claim and I didn't have to fight with my insurance co. they handled it all. In addition their construction work was beautiful! Have received many compliments from neighbors about quality of work. They were incredible . I left for work in morning and by the time I got home I had a new roof. Not a scrap showing anyone had been there. Same with siding and gutters. Also important to me,if I had questions somebody was always on other side of the phone!"

"The entire process was smooth from start to finish. The initial design for the kitchen utilized the space efficiently and looked fantastic. The quality of the products and vendors that were used are top notch. The construction crew arrived punctually at my home every morning. They were very skilled in their carpentry and at the end of each day they left the site as neat and clean as possible. The project ended on time and on budget. I love my new kitchen and new floor. We have been enjoying my kitchen and floors for two years now and never had to call for any repairs or adjustments. Thank You Magnolia!"

"Overall it went well. The only thing I would say is that initially they wanted to use a part from an entire faucet combo (cost about $168) when eventually the part could be purchased seperately for about $40.  But I asked questions and they accommodated by going pick up the part at home depot.  That was very helpful as we were able to get all the work done that day.  Jennifer was great to work with....very responsive and timely follow up.

Custom Home Builders FAQs, answered by experts

The average cost to renovate or remodel a home is $52,300, with most projects ranging from $19,500 to over $88,400. However, costs can vary significantly, from as low as $3,000 for a small project to $170,000 or more for a complete home remodel.

Several factors influence the total price, including:

  • Project Scope and Size: The extent of the renovations, whether it's a single room or the entire house.

  • Location: Geographic location affects labor and material costs.

  • Materials: The quality of materials chosen.

  • Room Type: Kitchen remodels ($14,500 - $70,000+) are generally more expensive than bedroom remodels ($1,500 - $5,500).

  • Other Factors: The time of year, complexity of the work, and any additions or expansions.

On a per-square-foot basis, you can expect to pay between $15 and $60 for standard projects and up to $150 for luxury renovations.

Examples of specific project costs include:

  • Basement remodel: ~$20,200

  • Garage remodel: ~$27,900

  • Loft conversion: ~$20,200

  • Disability accommodation remodel: ~$4,300

  • Major home repairs: ~$11,700

If you are financing the project, note that some loan programs, like the FHA 203(k), may require a minimum project cost (e.g., $5,000) and will necessitate a home appraisal and professional cost estimates. Using a home renovation cost estimator can also help you budget for your project.

A green home is one that focuses on conservation, with the goal often being net-zero carbon emissions and self-sustainability. It will often include some kind of self-generation equipment, like solar panels or a small wind turbine, high-efficiency electrical components and mechanicals, and high-quality insulation and air sealing to reduce the loss of conditioned air. Many green homes also include xeriscaping or rainwater collection to cut down on drainage and water consumption.

Typically, architects do not build homes in a hands-on sense of doing the actual framing, roofing, or other building. Architects usually do not have the training and experience to build the homes they design. An architect would need to know how to do the specific trades required to build a house, which is possible but not a common practice. A general contractor or homebuilder typically oversees the actual details of building the house that the architect designs.

Buying a house is easier than building one from scratch. Buying an existing home is almost always faster, even if you need to make renovations once you move in. When you hire the right team to build a home, they will simplify the design and build phases so that there is little guesswork throughout the process, but building new construction will almost always take longer than buying an existing home.

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.
