"I recently worked with Design X Architects on a tenant improvement (TI) project. We encountered several difficulties with the city that required design changes that I did not want to make. Design X was able to fight for what I wanted and get it through as is. They have a deep understanding of city codes and zoning, which enabled them to argue back to the city and make our vision a reality. I highly recommend them to anyone looking for an architect."

Opulent Design Build . One point of contact from Start to Finish. Opulent Design Build takes the complicated process of home designing, building and remodeling and makes it an experience that you will love! There's no need to fear the design & construction process. Opulent Design Build personally handles every aspect of the construction process: design, engineering, site survey, permitting, construction and inspections. We are truly a "one-stop" design-build company.

"My wife and I were looking into adding some square footage to our home as well as remodel. We were going in circles trying to plan and budget and it honestly was one of the most stressful/hardest experiences of our marriage. That was until we stumbled upon Opulent. I do not remember how we found them, but man, I am so glad we did. Eddie and his whole team were OUTSTANDING throughout the whole process. They really made us feel like we were part of the Opulent Family as well as producing real results. They managed EVERYTHING just about perfectly. From dealing with the permit process to helping us figure out what we needed to fill our space with beautiful fixtures to actually getting the construction done. The preconstruction process was so simple thanks to their amazing team and construction flowed so smoothly. The field workers were respectful and clean every day. 10/10 cannot recommend enough. Thank you Opulent!!"

Custom Home Builders questions, answered by experts

It is almost always more affordable to buy an existing home than to build one from scratch. First of all, new construction mortgage interest rates are often higher than traditional loans. Also, when building a home, you're covering the cost of brand-new finishes, appliances, electrics, plumbing, utility hookups, and labor. Between the cost of labor and permits, building a home will often cost more in the long run.

While many different factors determine whether a house is classified as a villa, many villas are detached homes with a European design influence, often with an emphasis on luxury and comfort. Modern villas often feature outdoor spaces such as terraces, gardens, or patios.

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.

Ranch and colonial-style homes are often the most affordable to build. They have a common layout with available designs that are easy to adjust in simple ways without having to spend too much on a structural engineer or architect. Both types of homes' symmetry, simple roofs, and often one or two-story plans mean they often fall in the $150 to $200 square-foot range, putting them right around average.

Shipping container homes last at least 25 years on average, but they can last even longer with proper maintenance. Since shipping containers are made from metal, they’re quite vulnerable to rust and corrosion. This issue is exacerbated in coastal areas or areas with a lot of precipitation. To extend the life span of your container home, install siding that protects the exterior.
