"Hired them 9/6/2025. They sent out a third party to measure the home. That third party never provided Evolution the measurements. Evolution sent out another third party and they measured the house at something like 2,400 sq ft. We were provided a draft of the house and almost all the measurements were off. We communicated with Eliza and Collin but the corrected drafts were inaccurate as well. All we were trying to do was convert a golf cart garage to a closet and connect an existing bathroom to that closet, which would have increased our square footage from 1,490 sq ft to 1,610 sq ft. We sent the accurate measurements that we took ourselves to Eliza on November 18, 2025. Today is December 29, and despite a follow up call to Collin a few weeks ago we still haven?t heard anything from her. Fortunately we only spent a few thousand dollars on these clowns and have now found a reputable local company who has many more five star reviews on Yelp and this site. Avoid them at all costs!!"

Custom Home Builders questions, answered by experts

Framing is often the most expensive phase of building a house because it’s time-consuming and requires a lot of materials. It costs between $20,000 and $50,000 on average, depending on materials and labor costs. Before construction begins, it’s possible that purchasing land is the priciest step in the process. Some plots of land sell for $3,000, while others cost upwards of $150,000.

A custom home is one that you design from the ground up, allowing you to customize everything from the square footage to the interior layout to all of the materials used. A spec home is one that a builder has designed and gotten approvals for. Spec homes may give you some limited options for the layout and materials, but most of the build is pre-set. Custom homes cost more and take longer to build.

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.

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.

Whether a prefab home is worth it or not will depend on your personal needs and preferences. Overall, prefab homes tend to cost less than traditional homes, although they also tend to have lower resale values. Another thing to consider is that prefab homes usually last 50 to 60 years or longer, while traditional homes last 50 to 100 years or more.
