Basement General Contracting. I am the general contractor, and I personally do the framing, tile, and trim. I also use a master plumber, master electrician, and drywallers who perform the work themselves instead of using apprentices.
"I’ve now used Darren and High-Quality Construction for multiple jobs. His prices are fair and transparent and he communicated well. At the end the work is great!"

Stellar Remodeling, Inc - Your trusted choice for all your remodeling needs! We are a family-owned business in Denver, offering top-notch expertise in bathroom and kitchen remodeling, as well as basement finishing. Contact us today for a stellar transformation!
"I would like to highly recommend Jack Wilson and the Stellar Remodeling team to any homeowners who are looking for a quality contractor. We first contacted Jack in 2013 to help us with a small kitchen remodel project. He helped us design and install a granite countertop and add trim detail around the kitchen window. This was a relatively small project but Jack was detailed and attentive to us throughout. We were very happy with the work so we called Jack for our most recent remodeling project which included a full kitchen and living room remodel. This was a HUGE project that went so smoothly and we are thrilled with the results. Jack worked with us to scope the project - planning every detail including cabinets, countertops, plumbing, appliance installation, backsplash and hardwood floors. Installation was very quick (about 4 weeks) with no issues and we have been enjoying the results ever since. The price was very competitive and the attention to detail is amazing. If you are looking for a general contractor who has the experience, reputation, integrity, flexibility and the ability to listen on your next remodel project, I highly recommend Jack and his team. You won't be disappointed."

FAQs for guest house building service projects in Castle Rock, CO
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.
