More Than a Tree House. A Place to Make Memories.

A great tree house becomes part of the story of a home. Whether it’s a place for kids to explore, a quiet retreat, or something completely unique, O’Shea Construction can bring your vision to life with thoughtful design and the same quality craftsmanship and attention to detail we bring to every custom project.


Every tree house is designed around the property, the surrounding trees, and how you want to use the space.

GET STARTED

Built for Whatever You Imagine

Your treehouse doesn't have to fit a template. We can create a space designed around your specific needs and vision.

Guest Houses

Give your guests a memorable place to stay with the comforts of a traditional home.

Kids' Play Spaces

Create an elevated space designed for adventure, imagination, and hours of play.

Private Retreats

A quiet place to disconnect, relax, and enjoy the surrounding landscape.



Home Offices

Create a workspace that's separate from the main house—and anything but ordinary.

Entertainment Spaces

Design a unique space for gathering, relaxing, and enjoying time outdoors.

Something Completely Custom

Have an idea that doesn't fit into a category? That's exactly what custom construction is for.

If You Can Imagine It, We Can Build It

Because these are custom-built structures, you're not limited to a standard treehouse design. O’Shea can incorporate many of the features and comforts you'd expect in a traditional home, along with specialty elements designed specifically for elevated spaces.

Possible features include:

Electrical

Plumbing

HVAC / mini-splits

Custom cabinetry

Glass windows

Custom decks

Wraparound decks

Drawbridges

Ziplines

Slides

Other specialty features

Whether you want the comforts of home or something completely unexpected, we'll work with you to bring your ideas together into a cohesive design.

Built With the Trees—Not Limited by Them

Every property is different. That's why O’Shea offers both tree-supported structures and free-standing structures built among the trees.

Supported by Trees

When the design calls for the structure to be supported by living trees, an arborist evaluates the trees and O’Shea engineers the structure accordingly.

Built Among the Trees

When a tree-supported structure isn't the right solution, a free-standing timber structure can be designed and built among the trees.

Hybrid Possibilities

The structure can also combine both approaches to create the best solution for the property and the vision.

Arborist Evaluation

Trees are evaluated to determine their suitability for supporting the structure.

Engineered Design

The structure is engineered around the specific conditions of the property and trees.

Specialty Hardware

Treehouse-specific hardware allows trees to continue growing while supporting the structure.

Designed With Safety and the Trees in Mind

Building in and around living trees requires careful planning. When a tree-supported structure is appropriate, O’Shea works with an arborist to evaluate the trees and engineers the structure accordingly.


Specialty treehouse hardware is used to allow the trees to continue growing naturally without negatively affecting the structure.

FAQ’s

  • 01 Can a treehouse be built without putting the structure directly on a tree?

    Yes. O’Shea can build structures among the trees using traditional supports when that is the better solution for the property and design.

  • 02 Can you build a treehouse on the trees on my property?

    Yes. When a tree-supported structure is appropriate, O’Shea works with an arborist to evaluate the trees and engineers the structure accordingly.

  • 03 What can I include in my custom treehouse?

    Treehouses can incorporate many of the features you'd find in a traditional home, including electrical, plumbing, HVAC/mini-splits, cabinetry, windows, and more. Specialty features such as unique decks, drawbridges, ziplines, and slides can also be incorporated.

  • 04 How long does a custom treehouse take to build?

    From initial design through completion, projects typically take approximately 3–6 months.

  • 05 Where do you build custom treehouses?

    O’Shea serves its existing service areas—including Spring Branch, Bulverde, Boerne, Canyon Lake, New Braunfels, and San Antonio—and is willing to travel farther for treehouse projects, including the Austin area.

  • 06 Do you handle permitting?

    Yes. O’Shea manages local permitting, zoning requirements, and HOA approvals for treehouse projects.
