"Hired Superb LLC to remove three thru the wall air conditioners, brick up opening on exterior and drywall interior opening. The interior drywall installation was very good. The brick installation on exterior wall was amateurish at best."

"Very Happy with choosing Golden Temple Builders for my construction needs. Nick the owner was very professional and clearly explained the stages of the project and was able to work with the pricing points that I could commit to. His team went above and beyond my expectations, and job was completed even well before promised. Would Highly Recommend!!!! 10/10"

"I don’t usually leave reviews but I had to write one for Rightway Construction. Great prices and even better customer service. They did our master bathroom and completely remodel our floors. We couldn’t be happier. I will re-hire them in a heart beat."

"J & H was phenomenal. Great price and an exceptional product. Replaced all kitchen countertops and installed new countertops on the bar. Could not be happier with the finished product. Answered all our questions and worked with us on customizing some items. Countertops and backsplashes all match patterns at the joints. Looks like one continuous piece. Highly recommend J & H."

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.

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.

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.

One of the best ways to negotiate with a homebuilder is to forgo price reductions. Instead, negotiate over upgrades and incentives, as many builders are more willing to go down that road than to decrease their own fee. Even if they were willing to take a cut, a reputable homebuilder often knows their worth, so a willingness to negotiate could be a red flag. Beyond that, builders are typically willing to negotiate closing costs instead of offering a discount on the base price.

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.
