"It gives me great pleasure to write this review for Unison Builds LLC. Chris and his team handled the complete interior and exterior renovation of our 7,500 square feet office building. Their work included adding seven new offices, a gorgeous marble kitchen and dining room, a wonderful reception area, an executive conference room with a 14-foot table, the CEO's new office, and nearly everything else. He is a reliable builder. His team takes great pride in what they do. And the work proceeded even faster than we expected."

"Stud Construction was professional and gave us great solution on the layout and finish of our 1500 sq ft basement. In addition to the basement we had them install hardwood floors in our dining area and living room and refinish the existing wood floor entrance. Justin was extremely responsive to inquiries and overall communication during all phases of the project. He was able to source subs in a timely manner and fix any concerns we had along the way. The subs were professional and respectful. We're very pleased with the finish and would recommend and use Stud Construction again."

Custom Home Builders FAQs, answered by experts

Yes, professionals offer mantel and surround customization for aesthetic appeal.

Local regulations dictate how big an ADU can be, and there may also be restrictions on the percentage of the main residence’s square footage an ADU can have. In most cases, an ADU must be smaller than the main residence, but check with your local building authority to confirm restrictions on ADU size.

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.

The early stages of building a house are harder than the later stages; laying the foundation and framing the house are two of the most challenging steps. However, it varies for everyone. Some people have difficulty installing HVAC, plumbing, and electricity, while others find it harder to plan the house and secure the necessary permits. 

Renovating or remodeling an existing structure is usually less expensive than the cost to build a new house. That’s because you can save on the costs of new building materials, laying a foundation, framing the entire building, and installing new materials and utilities throughout the house. However, if a home is in very poor condition or is incredibly old, you could spend more on upgrades and restoration compared to building from scratch.
