Underestimating the Construction Budget
Mistake:
Many first-time homeowners set their sights on a dream home but fail to account for hidden expenses such as government approvals, design changes, material price fluctuations, and interior costs.
How to Avoid:
- Plan a Realistic Budget: Always add a 10-15% buffer to your estimated construction cost for unexpected expenses.
- Get a Detailed BOQ: Request a Bill of Quantities from your contractor to understand all material and labor costs.
- Consult Professionals: Use a transparent and reliable builder, like Dezine and Build, who can provide you with clear costing and keep you informed throughout the process.
Skipping Soil Testing & Site Analysis
Mistake:
Skipping soil testing or proper site analysis can result in structural issues later, especially in regions like Chennai where soil types vary.
How to Avoid:
- Always Perform a Soil Test: Before designing the foundation, get a professional soil test done.
- Site Analysis: Ensure your architect evaluates sunlight, wind direction, and natural drainage before finalizing the layout.
Poor Space Planning & Design
Mistake:
Failing to optimize your house floor plan can lead to wasted space, awkward room sizes, or insufficient ventilation and light.
How to Avoid:
- Work with Expert Architects: Choose experienced architects who understand both your needs and local building codes.
- Prioritize Functionality: Focus on circulation, natural light, and future needs rather than just aesthetics.
- Review 3D Designs: Always ask for 3D walkthroughs to visualize your home before construction begins.
Overlooking Vastu, Orientation, or Local Norms
Ignoring Vastu guidelines, plot orientation, or local building regulations can cause delays, legal issues, or dissatisfaction after moving in.
How to Avoid:
- Check Compliance Early: Make sure your design aligns with local authority norms and Vastu principles (if you follow them).
- Get Approvals: Obtain all required permits and NOCs before starting construction.
- Consult Experts: Professional firms like Dezine and Build provide Vastu-compliant and regulation-ready designs.
Choosing the Wrong Contractor or Not Having a Written Contract
Mistake:
Selecting a contractor based only on price or without checking credentials can result in delays, quality issues, or disputes.
How to Avoid:
- Vet Your Contractor: Always check references, previous projects, and legal status.
- Insist on a Written Agreement: Ensure there’s a detailed contract covering scope, timelines, payment terms, and warranty.
- Monitor Progress: Stay involved, ask for milestone updates, and use project tracking tools offered by reputed companies.
Bonus Tips for First-Time Home Builders
- Plan interiors and storage from the beginning.
- Regularly visit the construction site or use digital tracking apps.
- Communicate openly and frequently with your architect and builder.
