Overview

Homes built around how your family actually lives

Building a custom home is the largest purchase most families ever make, and it is the one purchase with the least standardization. Two builders can quote the same plan and be forty thousand dollars apart because one priced a builder-grade window and the other priced a triple-glazed unit with a different warranty. Our job is to make those differences visible before you sign, not after.

Mavrix Build Co. builds on your lot or one of ours. We start with a site evaluation that covers setbacks, easements, topography, soil conditions, utility availability and the drainage plan, because a lot with a two-foot fall across the building pad is a very different budget than a lot with an eight-foot fall. We would rather spend three weeks getting that right than discover it during excavation.

From there our design team works with you on plan development, or we build from drawings you bring. Either way you receive a line-item specification book that names the window manufacturer, the insulation R-value, the cabinet line, the flooring allowance and the HVAC tonnage. When you compare our number to another builder, you are comparing the same house.

During construction you get a Friday update with photos and a look-ahead, a walkthrough at framing, and a selection schedule that keeps you ahead of the installers instead of behind them. Most of our clients tell us the schedule discipline was the difference between enjoying the build and surviving it.

Common Questions

Custom Homes FAQ

As of this year, most of our custom homes land between $215 and $345 per square foot of finished, conditioned space, excluding land. A 3,000 sq ft home with mid-range finishes typically comes in around $700,000 to $800,000. That range moves with lot conditions, structural complexity, site work and the level of finishes you select, which is why we publish a specification book rather than a single number.

Design and permitting usually take 3 to 5 months, and construction runs 8 to 16 months depending on size and complexity. Weather in Kansas City can cost us two to four weeks on a winter framing cycle, which we build into the schedule rather than pretend will not happen.

No. We help clients evaluate lots before purchase and we also hold a small inventory of improved lots in Johnson County and the Northland. If you are considering a specific parcel, we will do a site evaluation and give you a written buildability summary before you make an offer.

Yes, and almost everyone does. Changes are documented by written change order showing cost and schedule impact before work proceeds. Changes made after rough-in are the most expensive, so we front-load the decisions that matter during design and selections.

For select items, yes, such as appliances, light fixtures and specialty hardware. Owner-supplied items are excluded from our warranty and are installed under a documented acknowledgment. We will tell you up front where owner supply saves money and where it creates risk.

Every home carries a five-year workmanship warranty, a ten-year structural warranty, and manufacturer warranties on systems and materials registered in your name. We also schedule an 11-month warranty visit so anything that has settled or shifted is corrected before your first anniversary.
