Did you know that 60% of homeowners who build without professional guidance make mistakes that cost them up to 30% more than their original budget? Learn how to avoid them.
At Astrum Builders, we’ve seen projects ruined by seemingly small oversights. Here are the 5 most costly mistakes and how to fix them
Mistake #1: Skipping Soil Testing
-
Risk: Cracks, sinking foundations, and expensive repairs.
-
Solution:
-
Conduct a geotechnical study (average cost: $300-$800 USD).
-
Adjust foundation type (slab, piles, etc.) based on results.
-
Mistake #2: Choosing Cheap Materials
-
Risk: Moisture damage, electrical failures, or premature wear.
-
Solution:
-
Prioritize certified materials (e.g., ASTM standards).
-
Example: “Low-quality concrete blocks increase cracking risk in seismic zones.”
-
Mistake #3: Ignoring Legal Permits
-
Risk: Fines, demolition orders, or inability to sell the property.
-
Solution:
-
Required permits in [City/State]:
-
Building license.
-
Urban impact approval.
-
-
Estimated processing time: 1-2 months..
-
Mistake #4: Poor Space Planning
-
Risk: Narrow hallways, cramped kitchens, or poor natural light.
-
Solution:
-
Use BIM software to simulate traffic flow and ventilation.
-
Example: “A 10×10 ft bedroom is impractical for a king bed and closet.”
-
Mistake #5: Failing to Supervise Construction
-
Risk: Budget overruns, delays, or shoddy workmanship.
-
Solution:
-
Weekly site visits with a progress checklist (e.g., wall leveling, electrical systems).
-
Hire a construction manager (cost: ~5% of project total).
