Every guesthouse comes standard with…

  • Every Constructum project begins with fully developed architectural plans. From schematic layouts to detailed construction documents. These plans are crafted to meet city requirements while capturing the form, flow, and function of your guesthouse.

  • We coordinate a professional site survey to map your property’s boundaries, topography, and utility locations. This ensures every design decision is accurate, compliant, and tailored to your specific lot conditions.

  • Your project includes a complete engineering package — mechanical, electrical, plumbing, structural, and civil. Each discipline is handled by licensed engineers to guarantee safety, efficiency, and code compliance from the ground up.

  • We handle the entire permitting process. From city review fees and submissions to managing all correspondence and approvals. It’s one less headache for you, and one more thing checked off our list.

  • A dedicated project manager oversees every phase of your build, maintaining strict quality control and ensuring all work meets Constructum’s high standards. You’ll have one point of contact and full visibility from start to finish.

  • Your guesthouse starts with a structurally sound concrete foundation, poured and finished to exact specifications. It’s the base that supports everything we build.

  • From framing to finish, we use premium materials and proven techniques: 2x6 lumber framing, spray foam insulation, level 4 drywall, utility rough-ins, stucco exterior, and more. Every component is built to last and designed to impress. Our units are built using traditional construction methods and not pre-fabricated in a warehouse and shipped to your property. This ensures you receive the highest quality product.

  • Unlike many competitors who use wall-mounted mini splits, we install a fully ducted central air system… professionally engineered for balanced airflow and quiet, efficient comfort throughout the entire unit. We live in Arizona… Mini-splits just won’t cut it.

  • High-quality luxury laminate flooring comes standard and not as an upgrade. It’s durable, beautiful, and chosen for its ability to withstand daily use while maintaining a premium look.

  • Every guesthouse includes a complete kitchen appliance package: refrigerator, dishwasher, and your choice of a range or cooktop. All are selected for performance, style, and seamless integration with your design.
