About Castelan & Co.Houston, Texas / Design & technology

Design, with a working knowledge of real estate.

We design and build software, property websites, and interactive maps. We start with the property and the people who use it.

Our background

The experience
came first.

Property marketing. Tenant information. A website that needs updating. A team waiting on an answer.

It began inside a multi-property retail portfolio, where these were everyday responsibilities. We built the tools that work needed: content workflows, an interactive directory, and a shared website system.

We still work that way: learn how the property runs, then design and build what it needs.

A few examples.

Care is visible
in the details.

How a page reads. How a map moves. How easily someone finds what they came for.

We design the look, the interface, and the software underneath together, so they work as one.

Easy to use.

Clear layouts, plain language, and controls that behave the same way everywhere.

Built for everyday use.

Accessible interfaces, software that’s easy to maintain, and documentation your team can use after handover.
