When you choose to build a custom home in Oak Brook, you’re not just building a place to live, you’re creating a personal sanctuary tailored to your lifestyle, taste, and future. At SG Home Builders, we believe that your dream home deserves a process that’s just as custom as the house itself. That’s why, as a full-service Oak Brook custom home builder, our in-house design-build team manages everything—from finding your lot to the final walk-through ensuring a seamless, delay-free experience.
Here’s a detailed look at what it takes to build your custom home in Oak Brook, complete with timelines, estimated costs, and what you can expect at each phase.
Step 1: Define Your Vision
Timeline: 1–2 weeks
Cost: Free consultation
Every custom home starts with a conversation. During our initial meetings, we’ll explore your lifestyle needs, architectural preferences, and budget. This step includes discussing:
- Number of bedrooms and bathrooms
- Desired square footage
- Must-have features (home office, gym, outdoor living space)
- Design inspirations and priorities
Our team will translate your ideas into an actionable vision that serves as the foundation for everything that follows.
Step 2: Secure Financing
Timeline: 2–4 weeks
Cost: Varies by lender
Building a custom home typically requires a construction-to-permanent loan. We’ll connect you with reputable lenders in the Oak Brook area who specialize in financing for high-end custom homes. These loans cover the cost of the lot (if needed) and the construction, converting into a standard mortgage upon completion.
Estimated financial range:
- Lot purchase: $500,000–$1,000,000+
- Construction budget: $275–$350+ per square foot (varies based on finishes and complexity)
Step 3: Find the Perfect Lot
Timeline: 3-12 months
Cost: Typically included in home budget
Whether you already own land or need help finding the right lot, our in-house team handles the entire process. We evaluate Oak Brook lots based on zoning, topography, neighborhood aesthetic, and build feasibility. If needed, we can assist in demolishing an existing structure to make way for your dream home.
Step 4: Design Your Home with Our In-House Team
Timeline: 6-12 months
Cost: Included in total project budget
This is where your vision starts to take shape. SG Home Builders uses a fully in-house design-build model, meaning architects, designers, and project managers are all part of one unified team. This eliminates delays, reduces miscommunication, and accelerates approvals.
During this phase, you’ll:
- Collaborate on floor plans and elevations
- Choose materials, finishes, and features
- Review and approve detailed construction documents
Because we control the process internally, we avoid the common lag caused by outsourcing to third-party designers or engineers.
Step 5: Obtain Permits and Final Approvals
Timeline: 4–12 weeks
Cost: Varies by municipality ($5,000–$15,000+)
Oak Brook has specific zoning and permitting requirements, and our team is well-versed in local regulations. We’ll handle the full permitting process on your behalf, ensuring everything complies with city codes and HOA standards if applicable.
Step 6: Construction
Timeline: 10-24 months
Cost: Based on home design – generally $750,000–$2,500,000+
With permits approved and materials ordered, our construction team gets to work. Throughout the build, we keep you updated via project milestones and progress reports. You’ll also have opportunities to visit the site with your project manager.
What’s included:
- Site prep and foundation
- Framing, roofing, windows
- Plumbing, HVAC, electrical
- Interior finishes and final detailing
- Landscaping and exterior work
Because our team is fully in-house, we manage all trades, scheduling, and inspections keeping your project on time and on budget.
Step 7: Final Walk-Through & Move-In
Timeline: Final 2–3 weeks
Cost: Included
Once the build is complete, we’ll conduct a thorough final walk-through with you. Any punch list items are addressed quickly. We also take care of occupancy certificates, warranties, and guidance for maintaining your new home.
