They were on hand monitoring the subcontractors and making sure the job was done correctly. They did a great job and we are very gratefully for their hard work!"

"We found Landmark construction energy crew, after being frustrated in the past from other contractors. From the initial meeting that we had with Charlie, we were impressed. Their values of customer satisfaction and their deliver everything they said. Charlie was the manager of the work and he was on time for all the meetings that we had with him. He was very straight, kindly and motivated to be invited into our house. He came back and took all the measurements that he needed for the kitchen, asked us many questions about what we would like to include in the new kitchen and 3 days after, he brought us a 3D design for us to look at and see how it will most likely look like. It was exciting to see how fast they could generate a nice design. Charlie knew what he’s doing and we were sure he has done this type of jobs many times before. Their prices are reasonable. We wanted our kitchen finished as soon as possible, so we agreed with Charlie to start the following week. That gave us little time to buy all the appliances, hardware, countertops, tiles Etc… Charlie personally went with us to 2 showrooms where we picked out our tiles and countertops. He also helped us to search and buy all the options for the (sink, faucet, hardware and more…). To be honest, I was probably a nightmare type of work. We moved out of our place during the month of the remodeling and we were a little worried that something would go wrong and we would end up on a terrifying remodeling show. Now after this remodeling is over, we can say clearly that is nothing to worry about when Landmark construction energy crew are working at your house. Their workers was clean, friendly, willing to answer questions. I discovered that Charlie visits the job site every few days, but he too sincerely cares about your home. He always called regarding the schedule, timeline or if there was a problem that need to be solved. We asked for changes to the electric wiring after the tiles have been installed. Would I recommend them to others? Absolutely yes. We will refer this company to all our friends."

Custom Home Builders FAQs, answered by experts

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.

Modular homes are more affordable than stick-built homes if you keep quality and square footage equal. The cost to build a home averages $323,000, while average modular home prices sit at {AvgCost}. If you’re looking for custom or luxury options, a traditional custom home costs $825,000, while a high-end modular home costs $600,000, on average.

Remodeling a house is often less expensive than building a new house. You can expect to pay an average of $100 per square foot when you are remodeling. The cost to build a house averages about $150 per square foot. When remodeling, though, some rooms cost more than $100 per square foot and some cost less. Use a home renovation cost estimator to accurately estimate your remodeling costs.

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.

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.
