Woman Builds $33,000 Tiny Home for Mom on Family’s Texas Property

Yeli and Benjamin Heidecker built a roughly 400 square-foot tiny casita for Yeli’s mother, Liliana Villanueva, on their two-acre property in west-central Texas for about $33,000, the couple also described the final figure as under $32,000, completing the project in eight weeks after a fall 2025 decision to start the build. The family had bought the two-acre lot in early 2024 for $45,000 and live on the same parcel in a barndominium.

Villanueva had been living in an RV on the property while experiencing health issues, and the couple decided a small, permanent dwelling would be safer and keep “Abuela” close to their four young children. Liliana moved into the tiny home in November 2025 even though the interior was not fully finished; the bedroom is large enough to fit a queen bed. The home endured a January winter storm, and Yeli said, “It worked like a champ.” She added that her mother reacted, “It was so warm. It was so cozy.”

The Heideckers kept costs low by doing most of the work themselves. They contracted an expert only to build the shell and lay the concrete foundation for the tiny home; Benjamin carried out most of the hands-on interior work, installing the kitchen, painting, and putting up walls and drywall, while Yeli helped when she was not caring for their four children. The couple, both 32 years old, say those savings matter: professionals had quoted between $63,000 and $97,000 to build a comparable turnkey tiny house, and the family estimates they saved at least $30,000 by DIYing much of the job. The project was described as finishing “slightly over budget.”

Practical choices left trade-offs. The tiny home measures about 400 square feet; Yeli said, “It could have been like $2,000 to $3,000 more if we had gone maybe 2 feet more on each side, which would have made the house closer to 500 square feet instead of 400.” The shower entrance was designed for accessibility, but the doorways and bedroom size were not fully ADA accessible for future walker or wheelchair use, a regret Yeli highlighted.

Lessons from the build focused on patience and flexibility. Yeli recommended builders “be patient and be open to pivoting or making changes in the middle of it based on either budget or timing. I think it's very important.” She also reflected on the emotional payoff: “It was special because we built this for Abuela… It feels like it bonded us on a deeper level.”

The couple has not provided an itemized final cost breakdown or detailed permit and inspection records tied to the tiny home, and those specifics remain to be clarified for anyone planning a similar DIY accessory dwelling.
