We developed a vision of how we wanted to deck out our vacation home and DMH brought it to life! We have worked with Dillon and Tom for almost 3 years now. As a project finished, we kept adding more. They have built a spare garage that matches the house, an outdoor kitchen, lounge fire pit area, back up generator, sound walls, landscaping and even installed a commercial wine fridge to the pantry.
Homer & Lisa R.
It was difficult to find someone willing to take on a partially completed building and we were a year behind schedule.
DMH Development rescued us and began work on our Casita project a week after our first meeting.
The results are of excellent quality and we are so very pleased with the outcome of our Casita project.
Chris & Kelly C.
DMH Construction stepped in when we really needed help after another contractor abruptly walked away from our project. Tom and Dillon came into a difficult situation, assessed everything quickly, and immediately put us at ease.

Frequently
Asked
Questions
Common Home Renovation FAQs – Canyon Lake & Texas Hill Country
01. How much does it cost to build a casita in Texas Hill Country?
The cost of a custom casita depends on several factors, including square footage, site conditions, utilities, finishes, and overall design complexity. Most casita projects in Texas Hill Country fall somewhere between $175 to $225 per square foot. Detailed furnishings and luxury fixtures exceed this range. During your consultation, we'll help you determine a realistic budget based on your goals and property.
02. What is the difference between a casita and an ADU?
A casita is often considered a type of ADU (Accessory Dwelling Unit). In Texas Hill Country, homeowners commonly use terms like casita, guest house, granny unit, pool house, and mother-in-law suite interchangeably. The biggest difference is often how the space will be used and how local regulations classify the structure.
06. Do I need permits to build a casita in Texas Hill Country?
Most casita projects require some level of permitting and approval. Requirements vary by city, county, HOA, and property location. Our team can help guide you through the process and identify any project-specific requirements.
07. How long does it take to build a casita?
Every project is unique, but most custom casitas take several months from planning and design through final construction. The timeline depends on design complexity, permitting, site preparation, material selections, and weather conditions.
Avoid costly surprises before you build 🚧
05. Can a casita match the design of my home?
Absolutely. Most of our clients want their casita to feel like a natural extension of their property. We work to ensure the architecture, materials, finishes, and overall style complement your existing home.
03. Can a casita have a kitchen and full bathroom?
Yes. Many homeowners choose to include a kitchen, bathroom, living area, and bedroom so the casita functions as a complete living space. The final layout depends on your goals, budget, and local requirements.
04. How large can my casita be?
The size of your casita depends on your property's layout, local regulations, utility access, and intended use. Some homeowners build compact guest cottages while others create spacious detached living quarters. We can help determine what makes the most sense for your property.
08. Can you help if another contractor started the project but didn't finish it?
Yes. We frequently work with homeowners who have unfinished projects or need help getting a stalled project back on track. If you've already started planning, design work, or construction, we can evaluate the current situation and discuss the best path forward.
09. Does a Casita Increase Property Value?
In many cases, yes. A well-designed casita can increase both the functionality and appeal of your property by adding flexible living space that future buyers may find valuable.
Many Texas Hill Country homeowners build casitas to accommodate family members, host guests, create a home office, or provide additional living quarters. These features can make a property stand out in the market, especially when the casita is thoughtfully designed to complement the main home.
While every property and real estate market is different, a quality casita is often viewed as an investment that enhances how the property can be used today while potentially increasing its attractiveness to future buyers.
