"From the beginning of my project in January 2024, I have never regretted my decision to choose Ethos Building Group LLc. Jeh Johnson and his partner Tracy Herod have worked diligently to execute the itemized proposal that began this project to rehab, restore, and rebuild my home at 607 Wilmington ave. St. Louis MO 63111. An incredible number of tradesmen and tradeswomen have done their individual tasks all on a schedule professionally overseen by Jeh. These liscensed and masters of their trades worked alongside Jeh who if necessary stepped in and aided e these individuals. His overall expertise has brought my home to this point. One must keep in mind that a burnout like my home is an unusal job for Ethos Buildig Group LLc to accept. Yet at every stage my home has been given the same careful and thorough attention as their larger jobs. And despite some push back with my insurance company every thing has proceeded smoothly and orderly manner given the inevitable supply chain delays. Jeh Johnson is an affable young man who has facilitated all phases my prject and has even taken time to educate me on all the intricacies involved in a project such as mine. I cannot think of any single word to describe my experience with Ethos Building Group LLc but the forgoing will have to suffice. Thanks you for your kind attention. Stay safe and make a point of telling those who you find dear just what they mean to you."

"We hired Homesource to build a kitchen/hearth room addition onto our house. They were wonderful to deal with and we are extremely pleased with the results. Their carpenters, project managers and production crew were true professionals. We were also impressed with the expertise and professionalism of all the sub-contractors that they hired. We would highly recommend Homesource to anyone looking to build a custom home or remodel an existing home."

"I had some loose metal that was very dangerous if it had broken off. Mr Freeman was near by and was able to come reattach the metal. It was really cold but that didn't stop him from reattaching the loose portions. I was really grateful for the emergency work."

"Our kitchen was ugly and barely working.   We went to Angie's List and hired Good Neighbors, LLC for a previous job and we hired them again and they gave us an outstanding kitchen remodel.
Good Neighbors had previously done a master bath remodel for us in 2012, which we love!  So when it came time to update and remodel our outdated 30 year old kitchen, we again hired Good Neighbors to do the kitchen remodel.  
They gave us a price, they gave us a finish date and they finished within budget and they finished on time.  Impressive!
Our kitchen was a complete demolish from the ceiling to the floor.  We installed new cabinets, new appliances, new lights, granite counter tops and updated the electrical service and the plumbing.   We did a lot. 
Our kitchen, as with many older home remodels came with several surprises once the work started.   However, Good Neighbors was able to handle the required fixes flawlessly and perfectly.  Most importantly, we are thrilled with the end result.  Even the building insectors complimented their work.
One point worth mentioning, which we really appreciated, was the fact that the Good Neighbors personnel, Tom, Chris and Caleb showed up on time, worked hard all day and cleaned up every night.  They never let us down, never left us hanging nor left us a mess to clean up.
The finished kitchen is even better than we had imangined.   Good Neighbors is worth of a glowing recommendation from us and we recommend them for any interior remodel and proudly give them an A."

Custom Home Builders FAQs, answered by experts

In most states, you can build an in-law suite on your property as long as you follow local building codes. However, it's important that you have enough space on your property to accommodate the new structure. A functional in-law suite in your backyard will require between 300 and 800 square feet of space.

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.

It’s typically more cost-effective to move a building along with its accessories than to demolish and rebuild it from scratch. However, that’s only if you can move the accessories without damaging them. However, if you plan to demolish the accessories anyway, it is advisable to do so before the move to save costs.

How long it takes to build a log cabin depends on a variety of factors, including its size and design, and whether or not you have to clear the land. Construction can take a few weeks for a prefab log cabin on an established site, but up to eight or nine months for a custom cabin on undeveloped land. In comparison, the timeline to build a house is typically four to 12 months.

Building a new home can be more expensive than buying an existing one, depending on the housing market in your area. Many homeowners still find that building a new house is worth the investment as they can choose the exact layout they want, as well as to choose their own floors, wall coverings, appliances, and finishes. If you live close enough to the build site, you can also stop by to check on the builder’s progress, which can provide some peace of mind that the project is worth it.
