Years ago, Austinites Mark and Jody bought a decommissioned railroad caboose and parked it in their Boudin Creek backyard, with the dream of turning it into a hangout space or a casita of sorts.

This was waaaaay before tiny houses were all the rage, so they were pioneers ahead of the tiny house trend. But they’d never gotten around to doing anything with it, and it had became more or less a place to store things that would ordinarily go into a garage.

Then the pandemic hit, and as many families during that time, they were challenged to find a way to carve out both a home office for Mark, and a place for his and Jody’s two young sons to conduct remote schoolwork. Mark found himself working in the caboose out back, but it was a hollow metal enclosure, without insulation or climate control in Austin, Texas, which is inherently unfriendly to humans and their computer equipment. It seemed like a great time to launch their caboose conversion into a tiny house, but they were struggling with how to plan out the space and sought our interior design expertise to flesh out the interior.

Before: The Brief

Mark and Jody’s wish list for their train caboose / tiny house conversion included the following features:

  • Kitchenette, with a small sink, hot plate, microwave, mini-fridge, and maximum storage potential for kitchen supplies
  • Bathroom with a small shower
  • Sleeping accommodations for two, but they specifically wanted to be able to fit a king-sized bed somehow
  • Sofa and large TV, so they could enjoy movie nights as a family out in the caboose
  • Workspace for Mark, that would accommodate a standing desk and two large monitors
  • Broom closet or some sort of storage for cleaning supplies
  • AirBnB-friendly, in case they decided to list the caboose as a vacation rental

A train caboose being a train caboose, this project also had the unique challenge of fitting all of the interior zones around a jillion existing windows and exterior doors, all of which had to stay in their present locations, because it would just be too cost-prohibitive to change the metal exterior. There was also an area near the entry door that featured a higher ceiling level, with upper windows on those higher walls.

They had come up with a plan to create a small bathroom near the entry, which would extend underneath the higher bump-up so that the shower was underneath one of those high windows. Mark imagined a plant ledge above the shower, to take advantage of the natural light coming in from that window, and the steam from the shower. But as far as how to manage the rest of the space and all of the functional zones they needed, they were unsure where to put everything.

Here’s what Mark had put together on Sketch-Up:

I loved the mental image of Mark’s idea to create a very plant-centric bathroom. But making all of the other functionality fit into the remaining space in the caboose was super challenging until I hit on the idea to move the bathroom to the back of the railroad car. I realized that if I could get Mark and Jody onboard with the idea of letting their back door be part of the bathroom, we could fit a whole-ass tub and shower—which seemed like supreme luxury for any tiny house—and we could create an open concept space in the rest of the caboose, with a living area, kitchenette, and plenty of workspace for Mark. Plus, we could let all of the light from that bump-up area come streaming into the interior.

Here’s the layout I proposed:

In addition to this layout, I also suggested that they add uplight wall sconces to the upper walls of the bump-up area, to light this feature at night. As with all projects, Mark and Jody made a few tweaks to my spaceplan to make things work better for them, and y’all…


When you scroll down and see how this precious space turned out? YOU. WILL. DIE. WITH. CABOOSE. ENVY.


Now, before we go any further, I have to gush over Jody’s design sense and styling capabilities. I helped them pick out this sweet paint palette and greenlit some choices they made on finishes, but beyond that, all the credit for the cuteness you’re about to see belongs to Jody. I just wanted to include this project in my portfolio to show how collaborating with a professional interior designer can help even the most creative, visionary folks get un-stuck and expand the potential for their interior spaces.

Okay, now take a look at how this adorable caboose-slash-tiny-house turned out!

Here’s a look at the entry side of the caboose, with its cute little beadboard ceiling in pale aqua in the cupola, and Mark’s reimagined plant ledge.

Mark’s small, yet well-appointed home office workspace inside the caboose/tiny house is still located near the entry, but they opted to rotate it to the adjoining wall.

Now let’s take a look at the bathroom. It feels like an ice cream dream!

I’m a sucker for anything pink, but this pale pink geometric floor tile and butter yellow wall paint combo just makes me smile!

The best part of working on the project? This feedback from Mark:

I’ve loved the layout—an open cupola area makes the whole place seem much bigger than it is. And the light is epic.
