Our attention to detail and can-do attitude allows us to make your vision a reality. We are licensed and insured for over 35 years. Call now for your free consultation and estimate.

"I hired Paramount back in 2020 for work on the first floor and appreciated their work so much that I brought them back for the basement (fix/ update after mold repair) and second floor (bathroom and stairs update, new carpet). Like the first time, I really appreciated Ryan's suggestions on style and options, and the various contractors were professional and very kind about working around me and the cats. Ryan was ultimately more critical than me about details and appreciate that desire to do things right and as clean as possible. Would use again!... although that would require a new house at this point. 😁"

Design Exteriors specializes in large-scale Design and Build projects. Want your backyard to be the envy of the cul-de-sac when you host that Broncos party? Let us "trick" it out with a completely customized pergola, fire pit, water feature, privacy screening & specialty patios to set it all on. Want your home to be the loveliest on the lane? Let us design and install a gorgeous curb appeal revision for you. When you're ready to totally revamp your outdoor space and bring in the experts, we're the ones that you will love working with! We partner with homeowners to help them conceptualize what they want and/or need from their exterior home spaces and then we bring in our expert artisan crews to make that vision a reality. Our designs are characterized by elegant curves and sophisticated arcs we affectionately refer to as "Shoebridge Circles" after the lead designer (and owner of our firm) Cedric Shoebridge. Bricks, stone, and pavers have to be custom-cut to fit into these curves, but we know they're worth it because as we like to joke around the office, you never hear a grandma yell to the grandkids to "Gather Square!" We say, "Gather around," because it's circles that bring families together. We are proud to have an A+ rating with the BBB and have been a multiple Award Winner with Angie's List and Home Advisor. #GoBroncos

"If you have a yard that needs a magic touch and an expert's eye, (Cedric) Sonny and his team are the crew for you. We worked with them starting in spring of 2024, for a complete backyard renovation - down to the dirt in the entire yard, and we LOVE our new space. During the design process, with meet with Sonny several times to go over what we wanted, take measurements, etc. He listens very attentively and seeks to understand your exact needs. He masterfully came up with a design that included every functional element we wanted, and transformed space that had formerly been no man's land into useful, useable yard. He phases the project (if and as needed) to fit budget limits, and really tries to maximize what's delivered. During construction, his crews were on site, on time, every day they were supposed to be. This is rare in our experience. Sonny too was on site frequently to ensure things were coming together as expected. We of course kept eyes on the progression, and as things came up they were quickly dealt with. His crews were respectful of our property and kept it tidy (all things considered). At the end of the project, this was the shortest punch list we've ever had, and all (very minor) items were taken care of quickly and correctly. Things you should know: this type of work is expensive. More expensive than we would have guessed. Sonny is very transparent about pricing for every element of the project, but it adds up, and things will likely come up that no one could have precisely anticipated. He dealt with them quickly and openly and fairly, and I feel we ended on very good terms. He really works to get and keep things within the budget, so knowing your budget helps that process. This type of work (depending on project size, and ours was a complete yard and deck redo) takes time. We started the design in Spring, work started just after the 4th of July, and sod was laid in late September. The end product is worth it though! Id suggest getting on his radar late fall/early spring before you want the project executed so that you're early in line for busy season (they're a relatively small company). All in all, we would work with him again. It's an expensive undertaking, but when you're working with Sonny, you're getting the value of his design experience, relationships with his crews, and his attention to detail. This is a wonderful small, local business to support, and the relationship and partnership developed during the process is authentic and genuine, in addition to the quality of design and execution delivered."

Guest house building services FAQs

In most states, yes—you can build a guest house, but every city or county sets its own zoning rules and building codes. Before breaking ground, check local ordinances, confirm lot setbacks, and secure the right permits. A local contractor or design-build firm can walk you through the paperwork and site requirements so your project starts on solid legal footing.

Yes—homeowners often tap a few different financing tools. A home-equity line of credit (HELOC) lets you borrow against your equity as you need funds. If you prefer a lump sum tied directly to the project, a short-term construction loan can roll into a second mortgage once the build is complete. Cash-out refinancing is another option: you replace your current mortgage with a larger one and use the difference to cover construction costs.

When you build a guest house, you’re creating a separate structure for hosting visitors without the full amenities needed for permanent living. An accessory dwelling unit, however, includes a complete kitchen and bathroom, meeting building codes for a long-term residence. This key difference makes an ADU ideal for long-term occupancy or rental income, adding enduring value to your property.

How many rooms you need depends on how you plan to use the space. Aim for one bedroom per every one or two occupants to make sure everyone has enough privacy and comfort. Added living and dining areas give you extra functionality, especially for rental use or long-term stays.

Most homeowners pick somewhere between 600 and 1,500 square feet to fit all the essentials. Make sure your design supports one to two occupants per bedroom and includes enough common areas for comfortable daily living. A well-proportioned layout boosts both functionality and property value.

No—a guest house isn’t just a bump-out on your main home. A bump-out is a small extension within an existing room for extra seating or storage. In contrast, you build a guest house as a standalone building with its own foundation and amenities, giving you a fully separate living area that can boost your property’s versatility and value.
