Are You Ready to Build a Custom Home? 7 Things to Know Before You Start
A practical planning guide for Central Texas homeowners
If you are wondering whether you are ready to build a custom home, start by looking beyond floor plans and finishes. The earliest decisions involve where you want to live, whether the land can support the project, what you can realistically invest, how the home should fit your daily life, and which professionals need to be involved before design moves too far.
The most important takeaway is simple: secure and evaluate the land before finalizing the house design. A custom home should respond to its specific property, including its slope, access, utilities, easements, views, sun exposure, trees, drainage, and local requirements. Designing first and searching for a lot later can lead to expensive revisions or a plan that does not fit.
In Episode 40 of the Building With Breven podcast, Steven and Mike Byrnes explain seven things to know before building a custom home. This guide expands their discussion into a practical custom home planning checklist for homeowners in Austin, Lakeway, the Highland Lakes, and other Central Texas communities. It also follows Episode 39 on the biggest fears homeowners have before building.
Quick Answer How Do You Prepare to Build a Custom Home
Before building a custom home, take these seven steps:
1. Choose the area and evaluate the land. Decide how much land you want, how close you need to be to daily services, and whether a prospective property is buildable.
2. Set a realistic all-in investment range. Include the house, land, site work, utility extensions, financing, landscaping, outdoor improvements, furnishings, and a reasonable contingency.
3. Define how the home must support your life. Plan around household size, life stage, entertaining, storage, hobbies, accessibility, and daily movement through the home.
4. Bring in a builder before design is finalized. A builder can help align early design decisions with the lot, constructability, current pricing, and the total project budget.
5. Vet builders carefully. Review relevant work, references, communication, pricing clarity, project systems, and experience in the location where you plan to build.
6. Allow time for preconstruction and construction. Land selection, architecture, engineering, selections, pricing, financing, and permits happen before the physical build begins.
7. Start serious planning 6 to 12 months before your desired groundbreaking. Collect priorities and inspiration, speak with lenders, research land and builders, and begin the right conversations early.
1. Decide Where You Want to Build
Your location decision affects much more than the commute. Consider whether you want acreage, a smaller homesite within a community, waterfront property, Hill Country views, or proximity to shopping, medical care, schools, recreation, and family. Think about how much land you are prepared to maintain and whether the setting still works for the way you expect to live several years from now.
Online listings can help you understand available locations and price ranges, but a promising listing does not confirm that a property supports the home you want. Before purchasing land for a custom home, investigate access, boundaries, setbacks, easements, utilities, drainage, flood exposure, soil and rock conditions, tree restrictions, septic feasibility, and neighborhood or architectural requirements. A steep or heavily constrained property may still be buildable, but the site work and structural solution can materially affect the total investment.
Breven Homes uses the TUTS framework - topography, utilities, trees, and special features or size - when discussing land. Review the full guide to evaluating land for a custom home and the companion explanation of custom home lot preparation. For Texas properties that may need an on-site wastewater system, the Texas Commission on Environmental Quality septic-system resources explain that permitting, installation, and maintenance requirements apply and may be administered locally.
Questions to Ask Before Buying a Lot
• Will the intended home footprint fit within the buildable area after setbacks and easements are considered?
• Is legal and practical road access confirmed?
• Which utilities are present, and what would it cost to extend water, sewer, electricity, gas, or communications service?
• Will the property require a well, septic system, retaining structures, extensive clearing, or significant excavation?
• How will the property's slope, drainage, views, trees, and sun exposure influence the home design?
• Which city, county, development, homeowners association, or architectural-review requirements apply?
• Has a local builder, surveyor, engineer, or other appropriate professional reviewed the property before the purchase becomes final?
2. Establish a Realistic All In Custom Home Budget
A realistic custom home budget is not only the builder's price for the house. It should account for the land, surveys, design and engineering, financing and closing costs, permits, clearing, excavation, grading, driveway work, utility connections, septic or well requirements, landscaping, pools or outdoor living, window treatments, furnishings, and other items that may sit outside the construction contract. The exact categories and amounts depend on the property, scope, contract, lender, and jurisdiction.
Avoid planning at the absolute top of what a lender may approve. Building and design decisions evolve, and homeowners often discover upgrades or features they value after planning begins. A working contingency and clear separation between must-haves and optional upgrades create room for informed decisions without making the finished home financially uncomfortable.
Ask a builder to explain what is included, excluded, allowed for, or still unknown. Breven's episode on how builders price a custom home explains why square footage alone cannot predict the final cost. If financing will be used, review custom home construction financing and speak with construction lenders early. The Consumer Financial Protection Bureau home loan toolkit can also help borrowers prepare questions about mortgage terms and closing costs. Your lender's current written terms and qualified financial advice should guide financing decisions.
What Should Be Included in an All In Budget
• Land purchase and related closing costs
• Architecture, engineering, interior design, surveys, and testing
• Home construction scope and builder fees
• Site preparation, excavation, grading, drainage, and driveway work
• Utility extensions, septic or well systems, and jurisdictional requirements
• Permits, financing costs, insurance, and lender-required inspections
• Landscaping, irrigation, fencing, pool, outdoor living, and other owner projects
• Furnishings, appliances or fixtures not included in the contract, moving costs, and contingency
3. Design the Home Around How You Live
Do not begin with square footage alone. Begin with the activities, relationships, and routines the home must support. A growing family may prioritize flexible bedrooms, a game room, durable storage, and connection to outdoor space. Empty nesters may prefer single-level living, guest accommodations, lower-maintenance spaces, and accessibility that supports long-term use. Other households may need a workshop, home office, fitness room, sewing space, multigenerational suite, or storage for bikes and outdoor equipment.
Efficient planning can sometimes provide the function a homeowner wants in a smaller footprint. Consider adjacencies and daily movement: the route from garage to pantry, the distance from bedrooms to laundry, separation between noisy and quiet rooms, guest privacy, natural light, furniture placement, and how indoor rooms connect to views and outdoor living. These details make a custom home feel designed for the people who live there rather than designed around a target size.

Lifestyle Questions to Discuss With Your Design Team
• Who will live in the home now, and who may live or stay there in the future?
• Which rooms are used every day, and which spaces are only occasional wants?
• How often do you entertain, host overnight guests, work from home, or pursue space-intensive hobbies?
• Do you need one-level living, wider circulation, a future elevator, or other aging-in-place considerations?
• Where do groceries, laundry, sports equipment, tools, deliveries, and household clutter naturally move?
• Which views, trees, outdoor areas, and natural-light conditions should shape the plan?
4. Should You Choose a Builder or Architect First
For many custom projects, involving a builder before the plans are finalized can reduce avoidable redesign. The builder can review the lot, discuss constructability, provide current pricing context, and help the architect understand the project's investment range. This does not diminish the architect's role. It creates collaboration between design and construction while major decisions are still flexible.
A common problem is completing a dream design before the land and construction budget are understood. The homeowner may then learn that the plan does not fit the lot, conflicts with the site's orientation or restrictions, or costs substantially more than expected. Bringing the builder, architect, engineer, and interior designer into the process at the appropriate time helps the team design toward the same property, priorities, and financial target.
Before paying for preconstruction or design services, confirm what each agreement covers, who owns the plans, whether the homeowner can use them with another builder, and whether any agreement commits the homeowner to a future construction contract. Terms vary by company, so rely on the written agreement and obtain professional review when appropriate.
5. Choose the Right Custom Home Builder
The right custom home builder should have relevant local experience, clear processes, transparent communication, and evidence that the company can deliver the type of home being planned. A polished portfolio is useful, but it should be supported by homeowner references, active or completed project visits when available, detailed answers about pricing and scheduling, and a clear explanation of who will manage the work.
Pay attention to early communication. A builder who takes weeks to return calls, avoids direct questions, or cannot explain the next steps may continue those habits after the contract is signed. Interview several qualified builders, but compare more than the headline price. Review scope, specifications, allowances, exclusions, management systems, quality controls, warranty support, and the working relationship you can expect throughout design and construction.
Use Breven's detailed guide to selecting a custom home builder in Central Texas and the list of questions to ask before signing a home-building contract when evaluating your shortlist.
Questions to Ask a Potential Custom Home Builder
• How many comparable homes have you completed in this area and on similar properties?
• Can I speak with recent clients and see active or completed work?
• Who will manage my project, and how often will I receive schedule, budget, and progress updates?
• How do you develop pricing, define allowances, document exclusions, and approve changes?
• How do you coordinate the architect, engineer, interior designer, trades, lender, and inspectors?
• What has your historical preconstruction and construction timeline been for homes of similar size and complexity?
• How are quality checks, walkthroughs, closeout items, and warranty requests handled?
6. Understand How Long the Custom Home Process Takes
The custom home timeline begins before excavation. Finding and evaluating land, defining the program, completing architecture and engineering, making selections, establishing pricing, arranging financing, obtaining approvals, and securing permits all occur before construction. Revisions and response times across the owner and professional team can extend preconstruction, so the schedule should include decision deadlines and realistic turnaround assumptions.
In the episode, Steven describes roughly five to seven months as a possible planning allowance for some projects and about 11 to 13 months as a common construction discussion, while emphasizing that actual durations vary widely. A simpler home on a prepared site may move faster; a large or highly detailed home, difficult property, extensive permitting process, or delayed selections can take longer. These figures are not promises. Ask your builder for a project-specific schedule based on the property, design stage, jurisdiction, builder capacity, and current trade and material conditions.

7. Start Planning 6 to 12 Months Before You Want to Build
Six to twelve months before a desired groundbreaking is not too early to begin serious custom home planning. Builders and design professionals may have active backlogs, and the early work often takes longer than homeowners expect. Starting early allows time to evaluate locations, investigate financing, clarify priorities, compare builders, and develop a design that fits the property and budget.
Custom Home Planning Checklist for the Next 6 to 12 Months
• Write down must-haves, preferences, and features you do not want.
• Collect inspiration images and note exactly what you like about each one.
• Identify preferred communities, drive times, acreage needs, and daily conveniences.
• Discuss an all-in investment range and how land, financing, current-home equity, and cash may fit together.
• Speak with construction lenders if financing will influence the land purchase or project scope.
• Interview local builders before buying a difficult property or finalizing architectural plans.
• Request surveys, restrictions, utility information, and appropriate professional evaluations for shortlisted land.
• Ask preferred builders and architects about their current availability and realistic start dates.
The Biggest Mistake to Avoid Before Building
Do not finalize a custom home design before you understand the land. The lot determines how the home can sit, where vehicles enter, which rooms capture the best views, how sunlight reaches the interior, what foundation or retaining solutions may be needed, where utilities connect, and how setbacks and easements limit the footprint.
A concept plan can help clarify preferences, but the final design should respond to the actual homesite. It is usually easier to design a home for the land than to search for land that perfectly accommodates a completed design. Involving a local builder before purchase or during the due-diligence period can help identify questions that need answers before the lot and design decisions become expensive to change.
Frequently Asked Questions About Preparing to Build a Custom Home
What should I do first when planning a custom home
Start by defining where you want to live, the lifestyle the home must support, and the total amount you can comfortably invest. Then involve a qualified local builder while evaluating land and before the architectural design is finalized.
Should I buy land before designing a custom home
The final home should be designed for a specific property. The lot affects orientation, views, access, setbacks, easements, drainage, utilities, foundation considerations, and the size and shape of the buildable area. Evaluate the land carefully before completing the design.
Should I hire a builder or architect first
For many custom projects, involving the builder first or at least very early allows design decisions to be reviewed against the lot, constructability, current pricing, and the total investment range. The strongest approach is collaborative, with the builder and architect working from the same goals.
How much money should I set aside beyond the house price
There is no universal percentage. Build an all-in budget that identifies land, design and engineering, site work, utilities, permits, financing, landscaping, outdoor improvements, furnishings, owner-supplied items, and contingency. Ask the builder which costs fall inside and outside the proposal.
How long does it take to plan and build a custom home
The timeline varies by land readiness, design complexity, revisions, engineering, selections, financing, permitting, builder capacity, weather, material availability, and trade coordination. Request separate preconstruction and construction schedules with project-specific assumptions rather than relying on a universal number.
When should I contact a custom home builder
Contact builders while evaluating land or approximately 6 to 12 months before your desired groundbreaking. Earlier contact may be appropriate when a preferred builder has a backlog, the land is complex, or substantial design and approval work is required.
What should I bring to my first custom builder meeting
Bring available property information, your preferred locations, an honest investment range, financing status, inspiration images, room and lifestyle priorities, approximate timing, and a list of questions. You do not need completed plans to begin the conversation.
How do I know whether a lot is buildable
Confirm boundaries, access, setbacks, easements, utilities, drainage and flood considerations, topography, subsurface conditions, trees, wastewater options, and local restrictions. A survey and reviews by the appropriate local professionals may be necessary before making a final decision.
Can I use a floor plan I found online
An online plan can be useful inspiration, but it should be reviewed for the specific lot, local codes and restrictions, structural and engineering requirements, climate, specifications, budget, and the way your household lives. Revisions are often necessary.
How many custom home builders should I interview
There is no required number, but interviewing several qualified builders can help you compare relevant experience, communication, scope, pricing methods, systems, references, and fit. The goal is an informed comparison, not automatically choosing the lowest initial proposal.
Plan the Land Budget Design and Team Together
Being ready to build a custom home does not mean having every finish selected or every drawing completed. It means understanding the order of decisions and bringing the right people into the process before land, design, budget, and timing move in different directions.
