"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"

"Carlyle Nation is a true perfectionist. We had new baseboards installed after getting new flooring and hired Mr. Nation to do the final painting. We also had him paint some door trims, the inside of our front door, and replace a section of crown molding. He did an excellent job on everything for a reasonable price, showing true attention to detail. He also works late to make sure that he gets the job done. We would definitely hire him again."

"FL Project Masters was great to work with.  From the first meeting, he took time to explain what was involved to achieve our desired results and  recommend different options to suit our budget. Eric and his crew were very courteous and professional. They kept the house as clean as possible throughout the process and arrived on time, communicating with us via text to confirm times.  Eric checked in on all the work to make sure that everything was done properly. The job was finished on time and we were very happy with the results.  This project was the first stage of renovations on our new old home and we are looking forward to working with FL Project Masters again in the future!

"AAA construction is the contractor we hired to remodel our house. Kitchen, bathrooms, floors, essentially the entire interior of the home. From day one, until we moved in and even until recently when a small adjustment needed to be made, their professionalism, attention to detail and talents as contractors were second to none. We met with many contractors before we sat down with John to discuss our plans and before Dustin came to our house to start the remodel. I can honestly say that we were lucky in hiring them. These days it is difficult to find a skilled much less honest contractor to perform even simple jobs. When you add the knowledge and experience they have I believe it would be very difficult to match. Their work ethic is what some of us would refer to as old school. Again this is something you can appreciate after you meet with enough other companies and realize how many impostors there are in Dade County. With AAA you have a contractor with a college degree in this field. Do yourself a favor and in the very least contact them and discuss your plans. Feel free to contact me via email for a reference.

"We just moved to Florida and bought a home. Not knowing anyone and hearing a lot of horror stories made us very skeptical in our 'interview' process of contractors. We met with roughly 6 companies and made the great decision to go with Premier. Mike and his crew were awesome from the get go. He was always proactive in his communication with us and was also very interested in feedback regarding his employees- who were all great by the way! We are very happy with the quality of work and the time they were able to accomplish it in. I would highly recommend using Premier General Contractors for any project! *Disregard the dirt in the front yard, this wasn't due to the construction of Premier it was from replacing a Septic tank."

"Proceed with caution! Things started out fairly efficiently and then went downhill quickly. I had a small kitchen reno that shouldn't have taken more than a week to complete and 8 months later, it sat unfinished. There were some delays due to supply chain, however I would constantly have to chase to set up a time for the project to be worked on. Weeks would go by with no work done and when Tommie would come out, it was often at odd hours when he was rushed, performing sloppy work. I subsequently had to hire new people to complete the project (thanks, Angi!) who took over on wiring that had to be reworked, an outlet that was left non-functioning and was actually fixed by someone who took the time to repair it, and all of my tiling/drywall that was left incomplete by Tommie and his contractors. Furthermore, both my stove and countertop were broken during construction and I was never compensated for the cost to repair the counter and to buy a new stove which I ended up taking out of pocket. There may be bigger projects out there, but it is a fairly simple (decent) business practice to commit to working on something and to seeing it through to completion. What should have been an easy project left me living in a construction zone for over half a year."

Home Building FAQs, answered by experts

Above all, the downside to building a new house is a longer timeline. You need several months to finish the build, depending on the supply chain and labor availability in the meantime. Building a home compared to buying one is also more expensive, both in the building process and when it comes to mortgage rates and property taxes.

Buying a house is easier than building one from scratch. Buying an existing home is almost always faster, even if you need to make renovations once you move in. When you hire the right team to build a home, they will simplify the design and build phases so that there is little guesswork throughout the process, but building new construction will almost always take longer than buying an existing home.

An A-frame home can be cheaper to build than a traditional house, but that is not always a given. Prices can be fairly similar in some cases, depending on the location, design, and necessary site preparation. Costs for an A-frame typically run between $100 to $200 per square foot, which is comparable to the cost of a traditional home. The cost of an A-frame can come in under those numbers if you opt for a prefabricated kit.

A contractor can install your shipping container home in as little as 90 days. This is notably quick compared to a traditional home build, which can take more than a year (providing there aren’t permitting or construction delays that make the wait even longer). For the quickest installation, choose a prefab container home.

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.
