Why RJ Castle

A builder small enough that the owner knows your name

RJ Castle Homes' stated mission is to build an affordable, quality and innovative house that becomes your home by listening to what you need.

Built around you, not a catalog

Bob Armstrong started RJ Castle Homes because he spent years on job sites listening to homeowners describe the house they actually wanted — and watching builders put up something else. Every plan starts from your list, not ours.

You talk to the people deciding

This is a family-run builder. The Armstrong who answers the phone is the same one making calls on your project — no regional sales office, no handoff to a construction manager you have never met.

Decades of Wichita-specific experience

Bob has worked in Wichita residential construction since 1981. Contractor Thane Nelson brings 33 years in the building industry. That is local knowledge about local lots, soil, codes and subcontractors.

Google review

“6 months living in a new build from RJ Castle and couldn’t be happier. Attention to detail, quality work across the board and an absolutely beautiful house I get to call a home. Worked with this group during a remodel and now a new build, 10/10 on both!”

Nate Chadd
Google review

“I helped my parents move into a new built RJ Castle home a year ago, and they have been very attentive to the warranty repairs needed. Whenever an issue has come up they have been timely in responding. My parents feel safe and well taken care of by friendly hands.”

  • Shell with rough-in plumbing

    Finish it out as a workshop, hobby space or storage on your own terms.

  • Height for a mezzanine

    A clear span with nothing in the middle of it, so a loft level is possible.
