[Sendai] Mori Sekkei, a Good Design Award-winning architectural firm, to hold a wood condominium renovation seminar on May 30.

## Overview

Mori Sekkei Co., Ltd. (Representative Director: Kohei Yamamoto), an architectural firm and builder based in Sendai, Miyagi Prefecture, specializing in home building that utilizes local timber, will hold a renovation seminar in Sendai on Saturday, May 30, 2026. The seminar will focus on resolving common condominium issues such as "condensation, mold, inconvenient layouts, and insufficient storage" and regenerating them into warm, wood-filled homes.

This seminar is the second in a series of highly successful events held in November 2025. Kazuya Kotani (Masterplan) and Shinya Tomomasa (Toivo), pioneers in wood condominium renovation, will be invited as lecturers to propose new living options through condominium renovation using "domestically sourced timber," which is still rare in the Tohoku region.

## Seminar Background: Transforming familiar condominiums into "final homes"

Condominiums have unique challenges such as condensation, mold, and inconvenient layouts due to changes in lifestyle. On the other hand, they also possess many characteristics that can be utilized for comfortable living, such as structural strength and high airtightness.

Mori Sekkei applies the high design capabilities and construction techniques cultivated through custom-built wooden houses to condominiums. By combining improved comfort through "insulation renovation" and natural materials such as "Minamisanriku Cedar" from Miyagi Prefecture, they propose to transform often inorganic condominium spaces into "wooden homes" where residents can truly relax.

Due to the overwhelming number of applications and high satisfaction received at the previous seminar, with comments like "I felt the value of craftsmen's handiwork, which is different from standardized renovations," we are holding this seminar again to allow more people to learn about this option.

## Four Pillars of This Seminar

- **Improvement of thermal environment:** By renovating insulation and reviewing airtightness, we suppress condensation and mold, achieving a comfortable indoor environment.
- **Utilization of natural materials:** We use "Minamisanriku Cedar," harvested in our local Minamisanriku town. It enhances comfort through touch, sight, and scent, and boasts excellent strength and moisture resistance.
- **Functional layout and storage plan:** In cooperation with a professional organizing and storage advisor, we propose plans that consider the flow of daily life.
- **Reliable carpentry techniques:** Skilled master carpenters carry out high-quality construction, realizing homes where residents can live safely and for a long time.

By combining these, we will update uncomfortable existing condominiums into "final homes."

## Achievements of the 1st Seminar

The first seminar, held in November 2025, consisted of a morning session for industry professionals and an afternoon session for the general public, with a total of 30 participants.

During the 90-minute program, design methods utilizing condominium structures, insulation renovation, and examples of natural material use were explained. Participants gave feedback such as "I re-understood the value of construction by carpenters" and "I felt the appeal of comfortable living, which is different from standardized renovations."

Given the high interest in wood texture and construction techniques, this second seminar will also propose ways to enrich condominium living from both material and technical aspects.

## In Closing

The "Wood Condominium Renovation" proposed by Mori Sekkei offers a new option for enhancing the quality of life.
With high-quality natural materials, user-friendly layouts, storage plans, and reliable carpentry skills, we realize homes where residents can live comfortably even in condominiums.

We will continue to propose home building that allows residents to live safely and securely in their "final homes."
If you live in a condominium and are considering creating your "final home," please do not hesitate to consult us.
