Smart Design Choices Reduce Costs

Several design decisions influence what you’ll pay to build in the Prairie State too. Making smart choices during the planning process prevents budget overruns.

Here are some top ways to reduce construction costs through prudent Illinois home design:

  • Take advantage of open floor plans – Large open spaces minimize interior walls and finishings.
  • Build a smaller garage – Oversized 3-4 car garages waste money. Right-size based on usage.
  • Skip basement additions – Finished lower levels add significantly to concrete and framing costs.
  • Reduce ornamental stonework – Limit expensive stone veneers to accent walls only.
  • Simplify the roofline – Complex rooflines require more time, labor, and material waste.
  • Choose vinyl or fiber cement siding – Much cheaper than brick or stone finishes.
  • Select mid-grade finishes – High-end costs soar. Think semi-custom kitchens, not ultra premium.
  • Omit rarely used spaces – Nix unused formal dining rooms, sitting rooms, theaters, etc.
  • Right-size windows – Limit huge or arched windows requiring custom work.

Timeline for Completion

  • Planning and Design: 1-2 months for finalizing plans and obtaining necessary permits.
  • Site Preparation: 1-3 weeks for clearing, excavation, and leveling.
  • Foundation Work: 1-3 weeks for pouring and curing the foundation.
  • Framing: 1-2 months for constructing the basic structure.
  • Roofing and Siding: 2-4 weeks for exterior work including roofing.
  • Interior Work: 1-2 months for insulation, drywall, flooring, and interior finishes.
  • Systems Installation: 1 month for electrical, plumbing, and HVAC systems.
  • Final Touches: 2-4 weeks for painting, fixtures, and final inspections.
  • Landscaping: 1-2 weeks for basic yard work.

Overall, building a house can take approximately 8-12 months, depending on the size, complexity, and any unforeseen delays.

House Building Financing Options

When financing the construction of a house, several options are available:

  • Mortgage Loans: Standard mortgages can be used for newly constructed homes, especially those built by developers.
  • Construction Loans: Short-term loans that cover the cost of building. They are typically converted into a traditional mortgage after construction completion.
  • Personal Savings: Using your own funds to cover some or all construction costs, avoiding the need for loans.
  • Owner-Builder Loans: For those who plan to oversee the construction themselves. These loans require detailed plans and a proven track record in construction.
  • Home Equity Line of Credit (HELOC): If you already own property, a HELOC allows you to borrow against your home’s equity to finance construction.
  • Government Loans: Programs like FHA construction loans offer lower down payments and are more lenient with credit requirements.
  • Land Loans: If you’re buying land for construction, a land loan can finance this purchase, often combined with a construction loan.
  • Bridge Loans: Short-term loans that cover the gap between construction costs and long-term financing.

Building vs. Buying Which is The Better

Building a house offers the advantage of customization, allowing for a home tailored to personal preferences and lifestyle needs. It ensures modern construction with potentially higher energy efficiency and the use of the latest materials and technologies. However, building is typically more expensive and time-consuming than buying, with costs and project duration often unpredictable due to factors like material prices and construction delays.

Buying an existing home, on the other hand, is generally quicker and more cost-effective. It allows for immediate occupancy and often comes with established amenities like landscaping and neighborhood connections. However, it might involve compromises on design and potential renovation costs to update or personalize the space according to your tastes and needs. Buying also means dealing with the existing housing market, which can fluctuate in terms of pricing and availability.

The Bottom Line

While pricey, building a new house in Illinois brings the chance to fully customize your ideal residence. Understanding typical construction costs in the state and smart budgeting reduces chances for unpleasant surprises.

Focus on the essential elements you need in a home rather than expensive excesses. And having a trusted construction loan helps manage payments in line with the building timeline. If crafting your perfect Illinois home is a priority, proper planning makes the financing process manageable.
