We manage your build-out so you don’t have to.

Our in-house interior construction team oversees all tenant build-outs to ensure spaces are delivered to plan and on time. This allows our clients to achieve timelines that would be unheard of with third party contractors. We’re experts in delivering standard office space, specialized labs, Sensitive Compartmented Information Facilities (SCIFs) and everything in between.


Your one-stop shop for improvements.

Our offerings don’t end after a tenant moves into their space. Clients can utilize our interior construction team to make improvements to their space as their needs evolve.

As a developer and manager of more than 22 million square feet of commercial space, we understand building improvements. We are a major purchaser of goods and services related to electrical and plumbing, windows and doors, shelving, flooring and much more.

The next time you need work done, whether the job is large or small, take advantage of our volume discount buying power and have your work done by skilled St. John Properties professionals. View the project gallery below to get inspired.
