The Role of Your Home Builder

Your home builder is your project manager, advocate, and construction partner. At Brenn Luxury Homes, we manage every aspect of the process, from architectural design and permitting to materials selection and scheduling.

We provide fixed-price contracts wherever possible, giving you the peace of mind that your budget will stay on track. We believe in full transparency. Every cost is clearly explained up front, and we work with you to build a plan that matches your goals.

What Affects the Cost of Building a House?

Land and Location

Land prices vary widely between cities like Olathe, Shawnee, and Overland Park. A lot in a walkable neighborhood near schools or parks may cost more than a rural property, but may save you money on utilities and infrastructure. Soil conditions, slope, and tree coverage can also affect site preparation costs.

Square Footage and Layout

Generally, the more square footage you build, the more your home will cost. However, the layout is just as important. Open-concept floor plans, finished basements, vaulted ceilings, and larger garages can raise the price per square foot due to structural needs and labor intensity.

Architectural Style and Design Complexity

Brenn Luxury Homes offers full customization. Whether you’re building a modern ranch in Lenexa or a two-story Craftsman in Overland Park, your design will influence cost. Unique rooflines, specialty windows, or covered outdoor spaces often require additional framing, materials, and engineering.

Materials and Interior Finishes

Your selections for flooring, cabinetry, countertops, lighting, and appliances will have a big impact on your total cost. We help guide you through every choice to balance aesthetics, durability, and investment.

Many of our clients choose a mix of high-end finishes and smart savings to create spaces that feel luxurious and personal without going over budget.

Labor and Skilled Trades

Labor pricing depends on the size and complexity of your build, along with market demand. Our trade partners include some of the most trusted subcontractors in Johnson County. From foundation to finish, we coordinate every step for quality control and efficient scheduling.

Permits and Fees

Each city has its own permitting and inspection requirements. We handle the paperwork for you, which includes submitting plans, managing inspections, and covering impact fees where required. These costs vary by city and are included in your comprehensive estimate.

Other Costs to consider

Beyond the structure itself, there are additional costs to plan for:

  • Landscaping: Patios, sod, retaining walls, irrigation

  • Driveways and Sidewalks: Concrete or paver installs

  • Utility Hookups: Electricity, water, gas, sewer, and internet

  • Contingency Fund: A reserve for unexpected issues or last-minute changes

Average Cost to Build a Custom Home in the Area

In Olathe, Overland Park, and surrounding cities, the cost to build a custom home typically ranges from $175 to $325 per square foot, depending on finishes and design choices. That means a 2,500-square-foot home will generally fall between $437,500 and $812,500.

Premium finishes, large basements, custom outdoor living areas, or multi-generational layouts will increase the total investment.
