Mitsui Fudosan Group Presents Consulting Service for Aging Property Revitalization
A First for REFINING ARCHITECURE ®
Mitsui Fudosan will incorporate measures against COVID-19
into a 44-year-old rental property built to previous seismic standards, revitalizing it just like a new building
September 3, 2020
Mitsui Fudosan Co., Ltd.
Tokyo, Japan, September 3, 2020 – Mitsui Fudosan Co., Ltd., a leading real estate company headquartered in Tokyo, is working on a consulting service for aging property revitalization that utilizes REFINING ARCHITECTURE.
To meet the diversification of work styles and lifestyles which is now progressing due to the spread of COVID-19, construction will be completed on a property (a rental property in Nerima-ku, Tokyo built in 1976) that has incorporated the societal needs of remote work and measures against COVID-19 into the project plan.
REFINING ARCHITECTURE is a construction method that makes it possible to revitalize buildings built to previous seismic standards* just like a new building without dismantling them, and helps solve the societal problem of seismic upgrade of buildings built to previous seismic standards. Among its features, it also allows for low project costs and short project timeframes compared to a case of reconstruction.
Mitsui Fudosan will incorporate features such as measures against COVID-19 through contact-free and antibacterial measures in the common area, as well as securing a space for remote work in the residential area-- a first for REFINING ARCHITECTURE properties.

■A project plan flexibly adapted to changes in societal needs
- Measures against COVID-19 in the common area through contact-free and anti-bacterial measures
Mitsui Fudosan has implemented measures against COVID-19 in the common area so that tenants can live with peace of mind, such as by installing antibacterial gel in the entrance, installing attachments to the door handles that may be touched by a large unspecified number of people in places like the garbage storeroom, attaching antibacterial sheets to the buttons inside the elevator, and installing holders for antibacterial gel to the doors of each residence.
Measures against COVID-19 in common area
- Securing remote work space in residential areas
While remote work is becoming common as one of many diverse work styles due to the spread of COVID-19, needs are increasing to secure a space to concentrate and work inside the home. In this property, we transformed the former balcony area into living quarters, secured a space in the living room to be used as a remote work space and installed specialized outlets and recessed lights. In this way, the living quarters are designed to allow for flexible accommodation to new work styles and lifestyles.

■About REFINING ARCHITECTURE
REFINING ARCHITECTURE is a method of structural revitalization proposed by SHIGERU AOKI Architect & Associates. Unlike reform and renovation, it has the following features.
Features of REFINING ARCHITECTURE
- Seismic reinforcement that does not interfere with the outside view or exterior
We will eliminate walls and facilities when they pose no problems for seismic functions, reduce the weight of the building, and improve seismic functions using a unique reinforcement method not through braces, etc. - Low cost and reduced construction timeframe compared to reconstruction
We will refurbish facilities and exterior and interior at 70% of the cost of reconstruction. Because there is no need for dismantling and construction of a new frame, the construction timeframe is also reduced. *1 - Reobtained certificate of inspection, making it just like a new building in legal terms as well
All existing laws and regulations concerning the main building will be applied. As a result, we will obtain a certificate of inspection and guarantee liquidity of potential assets. In particular, with regard to structure, we will create a “home information record” *2 to leave a record of the maintenance and repair process. - Reduces construction waste and is environmentally friendly
Reuse of the existing frame makes it possible to greatly reduce the construction waste that is generated during dismantling.
