A $1M+ budget offers plenty of possibilities, and it will secure you a quality custom home in the Texas Hill Country housing market. However, what you end up with comes down to the lot you choose and how disciplined you are with the design once you start picking finishes and materials. In addition, building a custom home in this area comes with its own set of challenges and rewards. Those challenges include building around the terrain and ensuring your home stands up to the climate here.
This guide will cover what you can realistically expect to build with that budget and where your money will go.
Use the links below to go to the sections you want to read:Across Central Texas, fully custom construction typically runs $250 to $400 per square foot, with design complexity and finish level moving that number up or down. In practice, that puts a $1M+ budget right at the point where a true custom design-build project becomes realistic here, provided you stay within design constraints.
Depending on your lot and your priorities, that budget typically lands you with a home somewhere between 2,200 and 3,000 square feet in size, and that's accounting for land, site work, and design fees. If that size seems a bit small, keep in mind that building costs here run higher than in other parts of the state due to labor costs and the terrain-related challenges.
Construction is usually just 60 to 65% of a $1M+ budget. The rest splits across land, design, permitting, and a contingency reserve for whatever the project turns up along the way. Here's how that typically breaks down, based on our team's decades of Hill Country building experience:
| Budget Category | Typical Share of a $1M+ Project |
|---|---|
| Land and Site Work | 15–25% |
| Design and Architecture Fees | 8–12% |
| Structural Shell (foundation, framing, roof) | 25–30% |
| Finishes (cabinetry, countertops, flooring, fixtures) | 20–25% |
| Systems (HVAC, electrical, plumbing) | 10–15% |
| Permits and Contingency | 5–10% |
These are working ranges, however. Your lot and your finish selections will determine your actual cost. For a budget built around your specific site, access our free Central Texas Custom Home & Remodeling Cost Guide.
Every project starts with the lot. Land in the Hill Country has climbed steadily, and a buildable lot with good utility access can use up a large share of a $1M+ budget before construction even starts. Sloped or rocky sites push that further, since site prep like cedar clearing, limestone milling, and private wells adds considerable cost when city utilities aren't an option. On a lot like that, site work alone can run into the tens of thousands before framing begins.
Design comes next, and it's the phase where sticking to your budget really matters. The design of your house determines the scope, materials, and other major cost factors of your custom home. Architectural fees typically run as a percentage of construction cost, but having an experienced architect can save you money later since they can flag build issues before they happen. Working with a design-build firm can be beneficial as well since the architect is working alongside the construction crew, meaning a lower risk of miscommunication and mistakes.
Once the design is set, the shell of the house takes form. Your contractor will build up the frame, foundation, roof, and exterior walls in this phase. Foundation choice carries more weight here than in most of the state, since limestone and clay soils call for different engineering from lot to lot. Make sure you're working with a knowledgeable local builder who understands the land and climate here.
Once the shell is up, it's time to pick out those finishes you've had on your mood board. At this stage, you and your contractor pick out cabinetry, countertops, flooring, and fixtures. At the $1M+ level, that typically means upgraded cabinetry, natural stone or quartz surfaces, and windows built to handle Central Texas heat. It's a real step up from builder-grade and worth the extra investment.
Systems are the last major piece, and those include HVAC, electrical, and plumbing, along with home automation technology. In this climate, a properly sized and zoned HVAC system is a must. When working with the $1M+ budget range, you can expect a high-efficiency system and smart thermostats.
There are a few line items that tend to catch people off guard, such as the costs of:
The land itself
Landcaping/site work
Pools
Guest housing areas or outdoor kitchens
To keep your budget aligned with your goals, go over these additional factors with your contractor during the initial planning/design stages.
Not every home labeled custom comes from the same process, and at this budget, the difference shows up in exactly what you get for your money. Production builders work from a set menu of floor plans with limited room to change them, which keeps costs down because the same design repeats across a neighborhood. Semi-custom builders loosen that up a little. You can modify an existing plan or bring in your own materials, working within the builder's preferred systems and subcontractors.
A genuine custom home skips the template entirely, since an architect designs around your specific site and how you plan to use every room. At $1M+, that level of customization is realistic in the Hill Country, as long as the design stays disciplined about size and complexity. It's also where an architect-led design-build firm tends to stretch a budget further than a production or semi-custom builder, because the same team makes both the design and construction decisions.
Most custom homes in this range take 12 to 18 months from the first design meeting to move-in, with design and permitting accounting for 4 to 6 months of that and construction filling the rest. Rural lots that need a well, septic system, or extensive site work often add time on the front end. A lot with utilities already in place can move faster.
Before you start pricing lots or interviewing builders, here's a quick checklist for what a $1M+ budget in the Texas Hill Country typically covers:
Take time to really think about what you want in your home and how you want each room to support your daily life. When you are sure about what you want, reach out to a reputable contractor with local experience. Working with a design-build team can also reduce costs and streamline the process since you get every service from one team rather than coordinating between different ones.
Building a custom home here is personal. It might be the house you retire into, or the one where your kids grow up, and a $1M+ budget deserves a team that treats it that way. At J. Bryant Boyd, we've been designing and building custom homes across Central Texas for over 30 years, long enough to know exactly how far that budget goes and where it's worth stretching further. Our architects and our builders are the same team, so the number we give you at the first meeting is the number you can actually build to, and you're never handed off to someone new halfway through.
