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!!"

"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."

Custom Home Builders questions, answered by experts

Historically, Tudor homes originally stemmed from the 15th and 16th centuries, while Victorians appeared during Queen Victoria's reign in the 19th century. The design and structural differences are significant as well. The many types of Victorian architecture—such as Italianate architecture—typically feature ornate trim, wood siding, wraparound porches, and tall towers on top, such as belvederes. On the other hand, Tudor-style homes feature white stucco exteriors with exposed wooden rafters marking the house frame both inside and out.

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.

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.

Yes, you can finance new construction using a construction loan or a construction-to-permanent loan, or you can use a home equity line of credit or a cash-out refinance if you’re building a second home. Some mortgagors may have restrictions on DIY house builds, so be sure to check that you can get financing before starting your project.

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.
