Are Large-Scale Renovations Reaching Their Limits Amid Rising Material Costs?

Is It Time to Rethink Large-Scale Renovations?



In recent years, the landscape of large-scale renovations has drastically changed due to fluctuations in international conditions. The cost of construction materials, such as paints and waterproofing substances, has soared, with some reports indicating increases of up to 180%. This surge in prices and occasional shipment halts have led to the troubling realization that many renovation plans may no longer be viable.

Historically, large-scale renovations were based on the premise of conducting them once every 15 years, involving multi-million yen projects heavily reliant on the prices of materials at that particular time. Typically, these jobs were procured and executed in bulk. However, the current market instability poses some serious risks:

  • - The timing of renovations can lead to significant cost disparities.
  • - Prices may change after project estimates are provided.
  • - Supply shortages could result in halted work.

The Challenges Property Owners Face



Many condominium owners are grappling with considerable uncertainties related to renovation costs:

  • - It's challenging to predict how much repairs will actually cost.
  • - Owners struggle to respond to sudden price hikes.
  • - Calculating the ideal timing for renovations becomes increasingly difficult.

What was once a standard practice in the industry has now morphed into a highly risky investment decision, largely influenced by the market environment.

A New Approach: Dividing Renovation Tasks



To address these emerging challenges, a new approach to renovations has taken off—one that favors not completing all tasks at once.

Arrow Paint, a leading firm in the industry, introduces a service called "Kotsukotsu Mente" characterized by:

  • - No initial costs and a monthly subscription model.
  • - Spreading renovations over a 15-year period.
  • - A structured approach that minimizes the impact of price fluctuations.

With this model, condominium owners can:

  • - Avoid unexpected high-cost expenses.
  • - Mitigate risks associated with price variations.
  • - Establish a more stable long-term financial plan.

Insights from the CEO of Arrow Paint



Masayuki Somiya, the CEO of Arrow Paint, shares important perspectives:

"Traditionally, large-scale renovations have been perceived as a task to address every 15 years. However, we are currently facing an unstable era regarding material costs and supplies. Continuing with the old approaches could lead to heightened risks. The focus should shift from 'Should we renovate all at once?' to 'How do we spread out our efforts and stabilize costs?' Kotsukotsu Mente aims to provide solutions for this new mindset."

Future Developments



Arrow Paint is actively expanding this service nationwide, with a steady increase in inquiries. Furthermore, they conduct seminars and online information sessions specifically for condominium owners, enhancing awareness about the differences between traditional large-scale renovations and modern strategies.
