Your Roadmap to Custom Home Building: What You Need to Know Before Starting

1. Define Your Vision

Before diving into the logistics, take time to clarify your vision for your custom home. Start by assessing your current house and identifying what works and, more importantly, what doesn't. This process will help you figure out what to prioritize in your new home.

• Make a list of rooms you don’t use or spaces that feel cramped, dysfunctional, or unnecessary. 
• Highlight the features you wish you had, whether that’s a larger kitchen, more outdoor living space, or a dedicated home office.

Key areas to consider include:

• Exterior: How do you want your home to present from the outside? 
• Owner’s Suite: What size, layout, and features (like a walk-in closet or spa-like bathroom) are important to you?
• Kitchen: Consider the layout, storage, and whether you need additional features like a dual kitchen concept.
• Bathrooms: How many bathrooms do you need? What types of features are essential?
• Great Room: Do you envision a variety of seating options for movie nights or an open-concept space for entertaining? 
• Outdoor Spaces: Do you want an expansive deck, a pool, or a built-in outdoor kitchen?

Start Your Inspiration Board!

Once you've outlined your needs, it’s time to get inspired. Start a Pinterest board or Instagram folder to save images of homes, rooms, or design elements you love. This will help you define your style and preferences.

2. Figure Out Where You Want to Live

Once you’ve envisioned your ideal home, the next step is figuring out where you want to build. Choosing the right location is just as important as the home itself, and there are several factors to consider:

• Size of the property: Do you want a large yard for outdoor activities, or are you looking for something smaller and low-maintenance?
• Proximity to neighbors/privacy: Are you looking for a secluded, private lot or do you prefer a more community-oriented neighborhood?
• Distance to Washington D.C.: How close do you need to be to the city for work, commuting, or other activities?
• School district: If you have children or plan to in the future, researching the local school district is essential.
• Community amenities: What’s important to you—parks, shopping centers, walking trails, or golf courses?
• Cost of lots: Prices vary greatly depending on the location and the size of the lot.

3. Discuss Your Budget

One of the most crucial aspects of building a custom home is setting a realistic budget. Having a financial plan in place early on will help you avoid falling in love with a design or location that’s beyond your means.

Consider a Preliminary Financial Assessment

A good starting point is to speak with a lender and complete a preliminary loan application. This step will give you a clear understanding of how much you can borrow and whether there are any areas where you need to improve your credit or savings.

Keep in mind: Interest rates can fluctuate, and while they're an important consideration, the cost of land and construction typically rises steadily over time. Waiting for lower rates doesn’t always guarantee savings if rising costs offset potential gains.

Budget for three main categories of cost:

• Lot Cost: the cost of purchasing the land to build on.
• Site Costs: the cost of preparing the land for construction. What are Site Costs?
• Design-Build Costs: the total construction cost of your house including architectural plans, structural plans, civil plans, permit fees, and the materials and labor of construction.

4. Plan Your Timeline

Building a custom home takes time, often around two years from start to finish. If you have a target move-in date—such as before school starts, a new job, or other life milestones—you'll need to work backward to establish when to start the project.

Typical timelines include:

• Design Phase: This can take several months, depending on the complexity and customization of your home's design.
• Permitting and Site Preparation: These steps often require additional time based on your lot’s location and the county's local regulations.
• Construction Phase: On average, it takes about 12-18 months, but can vary depending on the home’s size and complexity.

5. Research Architects and Builders

Now comes the most important decision: choosing your architect and builder. These professionals will guide you through the process and ensure your vision becomes reality.

You’ll also need to decide on a method such as design-build, design-bid, or architect-led.

• Design-Build: In this approach, one firm handles both the design and construction. This often leads to better communication, faster timelines, and fewer unexpected costs. At AV Architects + Builders, we offer design-build services to streamline the process for our clients.
• Design-Bid: In this more traditional approach, you hire an architect to design your home, then bid out the construction work to builders. While this can give you more control over specific elements, it can also lead to higher costs and longer timelines.
