What custom actually means here

A house built from your list, not from ours

Plenty of builders use “custom” to mean you picked one of four elevations and chose a countertop. RJ Castle Homes exists because that gap frustrated its founder: Bob Armstrong spent years on Wichita sites as a residential plumber, listening to homeowners describe the house they wanted and watching the industry hand them something close but not quite.

  • Your plan, not a catalogue

    Layout, room proportions and ceiling treatments are decided in conversation.

  • One number to call

    The person on the other end of that conversation has the authority to say yes.

  • Local subcontractors

    The same trades RJ Castle has used across decades of Wichita projects.

  • A firm quote before you start

    Priced from a settled plan and settled selections, not from a range.

The stated mission has not changed — to build an affordable, quality and innovative house that becomes your home by listening to what you need. Construction is overseen by John Armstrong, a licensed general contractor, with contractor Thane Nelson, who has 33 years in the building industry.

Where we build

Wichita and the surrounding Sedgwick County area, including our own communities at Casa Bella and Emerald Bay Estates. If your lot is elsewhere in the metro, call and ask — whether we can take it depends on the lot and the current build schedule.

The process

How a custom home with RJ Castle Homes goes

Six stages, in order. No stage starts before the one before it is genuinely settled — that is what keeps a custom build from turning into a series of expensive surprises.

  1. 01

    The first conversation

    Call (316) 768-6059 or email John directly. Do you own a lot, or are you looking at one of our communities? What is the budget band, and what are the two or three things the house absolutely has to do? Nothing is designed yet — we are working out whether the project makes sense.

  2. 02

    Lot and plan

    Setbacks, slope, orientation, utilities and HOA requirements narrow what is possible before a line is drawn. We already know the lots in Casa Bella and Emerald Bay Estates; if you brought your own, we walk it with you.

  3. 03

    Design and selections

    Where a floor plan becomes yours: layout, room sizes, ceiling treatments, kitchen configuration, primary suite, garage bays — then cabinetry, flooring, tile, lighting and fixtures.

  4. 04

    A firm quote

    With the plan and selections settled you get a real number, not a range. Better to have the hard conversation about scope now than mid-build.

  5. 05

    Construction

    Licensed general contractor John Armstrong oversees the build, with the subcontractor base RJ Castle has used across decades of Wichita projects. The person who answers your call is the person who can answer your question.

  6. 06

    Walkthrough and move-in

    A final walkthrough before you take the keys, so anything that needs attention gets identified and addressed while the house is still ours to fix.
