Read: Builder fees, contingencies, cost-plus, construction manager at risk, architect and design fees, and much more


Building a custom home is a dream come true for many individuals. The opportunity to design a residence that perfectly suits your needs and preferences is both exciting and challenging. One of the most crucial aspects of this process is predicting the cost of your custom home accurately. To avoid budgetary surprises and ensure a successful project, here are some key points to consider when estimating the cost of your dream home.


1. Define Your Vision:

Before diving into cost estimation, have a clear vision of what you want in your custom home. Outline your preferences for architectural style, room layouts, materials, and any special features you desire. This detailed vision will serve as the foundation for your budgeting and decision-making throughout the process.


2. Size and Layout:

The size and layout of your custom home will significantly impact its cost. Larger homes generally require more materials and labor, leading to higher expenses. Be mindful of the number of rooms, bathrooms, and the overall square footage you want, as it plays a crucial role in determining the budget. While square footage is one indicator of cost, it should only be used early on before you have made selections about what materials to use.


3. Location, Location, Location:

The location of your custom home matters in terms of both land costs and construction expenses. Is the market very competitive? Is it a bad month to buy lumber? Is a specific location on your site more difficult to build in than others? Blasting away rock and scraping the earth into an elegant site location for your new home design can be more costly than in an open field. The condition of the land where you plan to build your custom home is another cost-determining factor. Sites with significant slopes, drainage issues, or the need for extensive groundwork may require additional funds for site preparation.


4. Construction Materials:

The choice of construction materials significantly impacts the cost of your custom home. High-end materials may elevate the budget, while more budget-friendly options can help save costs without compromising on quality. Strike a balance between quality and budget to ensure a satisfactory outcome. How much time are you willing to spend researching or having your architect research the best deal on materials for your new home? We've seen clients save 50-80% on searching for alternative interior design selections, just by putting in a few hours of their own time.


5. Labor Costs:

Skilled labor is vital for constructing a custom home that meets your expectations. Hiring reputable and experienced professionals will generally come at a higher cost, but their expertise will ensure the project's success and avoid potential rework expenses. Certain architectural materials for your home, like large format tile, may be surprisingly more expensive than similar polished concrete finishes. That is why early on in our process, when designing your new home, we work with clients to get ahead on interior design finishes and specifications for tile, cabinets, wood, plaster, millwork, fixtures, appliances, and more.


6. Permits and Regulations:

Obtaining the necessary permits and complying with building regulations is a non-negotiable expense. Familiarize yourself with local building codes and associated costs to avoid any unforeseen financial setbacks. Separate architect fees can be accrued for regulatory meetings with local Design Review committees, environmental conservation commissions, and zoning boards.


7. Contingency Budget:

Even with careful planning, unexpected costs may arise during construction. It's prudent to set aside a contingency budget, usually around 10-20% of the total project cost, to account for any unforeseen expenses.


8. Energy Efficiency and Sustainability:

Consider the long-term cost savings that energy-efficient features and sustainable materials can bring to your custom home. While these upfront costs may be higher, they can lead to significant savings on utility bills in the future. Heat pumps, geothermal design, water heat recovery, passive solar orientation- all of these advances green design technologies for your new home should be considered early on as an upfront and lifecycle cost for your future. Some State regulations for energy requirements of new homes even mandate the implementation of green design technologies that you should be aware of early on.


9. Architect Design Fees Near You

For new homes, architect fees are typically calculated as a percentage of the total construction cost. This percentage can range from 10% to 15% or more, depending on the level of customization, design complexity, and additional services required. According to homeguide.com, the national average has this range due to the economic variety across the country. Additionally, the National Association of Home Builders discusses in 2022 costs of building new homes nationally, which calculates developer lead projects for non-custom houses that often have architect fees on the lower end of the spectrum for housing developments. In conclusion, clients can reach out to multiple architects and home designers by searching 'architects near me', or adding in 'Residential architects near me' or 'New home design firm near me' and reach out to firms to get their rate cards or ask about cost and fees for similar projects. Additionally, certain web services are dedicated to reporting data for what typical fees should be, such as architecturalfees.com, or the Architect Institute of America.


10. The most common construction delivery methods include Design-Bid-Build (DBB), Design-Build (DB), Construction Management at Risk (CMAR), and Integrated Project Delivery (IPD), among others. Each of these methods has distinct characteristics and contract structures, but none of them are commonly referred to as "Open Checkbook." However, with the industry facing rapid demand in the last few years, the term open checkbook has been more frequently used colloquially by builders of new custom homes, renovations, and additions to refer to CMAR when your general contractor secures bids from subcontractors, and lets the owner have a chance to review the numbers. The cost of the services are not hidden from the owners, but shown upfront, and the General Contractor lets the home owner know what their fees are for garnering bids and overseeing the work as a GC and Project Manager. This has been increasingly popular in 2023 for architect designed new homes and construction to help build trust between all parties.


Conclusion:


Predicting the cost of a custom home is a complex task that requires careful consideration of multiple factors. By having a clear vision, understanding the key points mentioned above, and working with reputable professionals, you can embark on your custom home journey with confidence. Remember that flexibility and adaptability are essential throughout the process to ensure a successful project that aligns with both your dream and your budget. Happy home-building!
