"Bruce Robinson I would unreservedly recommend Lionel Martinez, L Martinez Construction LLC, for any home construction job, from a remodel to a new home build. Lionel is a superb builder as well as an honest businessman. We hired Lionel for a significant construction job on our existing home. Lionel laid out the job in detail, provided a thorough estimate, and came in on budget. Based on that excellent experience, we had him build us a cabin in the mountains. Lionel was an exemplary contractor, laying out the project, establishing both fix prices and allowances based on the component of the job, and stuck to these prices without the shifty add-ons that you get from many contractors. His workmanship is superb, and he has a network of subcontractors who also performed at a high level. He ensured that his workers and subs kept the job site clean and completed the work to his exacting standards, even if that required additional work. Finally, he worked with my wife and me to make sure the finished product would exceed our expectations. In the case of our cabin, there was no mystery about the budget, and no surprises - the cabin came in on budget as well. Having had other experiences with contractors that left us unsatisfied, I can say that from the workmanship to the budget, Lionel Martinez exceeded our expectations in every way."

"I saw Annex Builders LLC build our neighbors garage and I asked them for a quote to stucco our house. The price was very reasonable and they completed the job very satisfactorily. At the same time they redone our entire roof. I will definitely hire these guys again for any job, big or small."

Custom Home Builders FAQs, answered by experts

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.

Ultimately, a work warranty is only as reliable as the contractor you’ve hired. That’s why trust and reputation are such important factors, in addition to having a solid contract and confirming appropriate licensing, insurance, and bonding. When looking for a contractor, it’s a good idea to read online reviews and ratings to see what kind of experience past customers have had. Issues with your contractor can make for an unsatisfying renovation process, but a reliable contractor can make the process go as smoothly as possible.

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.

Whether it’s more affordable to gut a house than build a new one depends on the markets where you'd be buying and selling. However, it’s usually less expensive to renovate a home than to build new construction. 

Most homeowners pay between $100,000 and $200,000 for demolition and remodeling costs, whereas the average cost to build a new home is between $139,000 and $531,300.

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.
