A 100 square meter raw unit requires a phased approach: structural assessment, full demolition, new framing, insulation, plumbing/electrical upgrades, and finishes. Prioritize load-bearing walls, code compliance, and energy efficiency.

Hardcore renovation demands meticulous planning due to the unit’s small size, which intensifies cost and time constraints. Structural evaluations reveal hidden issues in 60-70% of projects, per the National Association of Home Builders (NAHB). Demolition removes 80-90% of existing materials, creating a clean slate but increasing debris disposal costs by 15-20%. New framing must align with local building codes, which vary by municipality, adding 8-12 weeks to timelines. Insulation and HVAC upgrades reduce energy bills by 30-40%, as shown by the U.S. Department of Energy. Plumbing/electrical work requires permits, delaying projects by 7-14 days on average. Finishes like flooring and paint account for 40-50% of total costs. A 2023 Remodeling杂志 study found the average cost for a 100 sqm renovation is $45,000-$65,000, with labor comprising 35-45%. Sustainability trends drive 35% of homeowners to choose eco-friendly materials, adding 10-15% to expenses. Proactive budgeting and contractor vetting mitigate risks. For example, a 2022 Joint Center for Housing Studies report noted that 40% of U.S. renovation projects face delays due to unforeseen structural issues, underscoring the need for rigorous upfront planning. Ultimately, the process balances cost, compliance, and functionality in a space where every square meter impacts usability.
