Floor plan changes and extensions
While making use of the pillars and beams of your beloved home, we will change the floor plan and sometimes expand it to propose a home that is easy for your family to use.
In addition, by simultaneously performing insulation and seismic retrofitting, it will be a home that will be passed down to the next generation.

Plumbing Renovation
In places where water is used, even the smallest cracks can allow water to get in and cause damage to the floor and foundation. We propose renovations that respect the convenience and taste of your family.
Kitchen
Different kitchen layouts, like peninsula, L-shape, I-shape, and island-shape, come with varying usability and price considerations. Open-type plans that prioritize family time are trendy. Modern built-in appliances, such as dishwashers and induction cookers, make cooking easier. Custom-made or semi-custom-made unique kitchens are also popular.
Bathroom
Replacing your bath with a system bath that minimizes water leakage concerns and offers excellent insulation is a popular choice. You can choose from various types, including easy-to-clean and comfortable options. When it comes to vanity units, select one that suits your lifestyle preferences.
Toilet
Over the past few decades, water-saving toilets have significantly improved their water efficiency compared to the past. Manufacturers now offer options that prioritize ease of cleaning and resistance to dirt buildup. Additionally, tankless toilets, which are compact designs that create a spacious and stylish bathroom environment, are gaining popularity.
Energy-saving InstalLation
To create a comfortable home through insulation renovations, you need the right knowledge and construction techniques. We offer true comfort by focusing on high airtightness and insulation, which we’ve been working on since early stages. Even for partial insulation improvements, we ensure effective insulation and airtightness
Installation of interior windows
In the context of insulation renovations, partial improvements can be cost-effective while still delivering significant benefits. Additionally, the installation of double-glazed windows provides secondary advantages such as improved soundproofing and security.
Wall, Floor, Ceiling Insulation
Insulation projects can be quite substantial. It’s essential to understand that insulation isn’t just about adding material, but it requires proper “airtightness” measures to truly perform. Rushed insulation work can lead to condensation within the walls, potentially shortening the building’s lifespan.
Our approach involves thorough on-site assessments and repeated blueprint evaluations to recommend the best methods for your specific needs
water heater replacement
Within household energy consumption, approximately 30% is attributed to water heating. Surprisingly, replacing your water heater with an efficient model can lead to significant savings. Moreover, new water heaters like energy-efficient heat pump units and hybrid systems are now available, and their adoption is expected to increase efficiency further
heating unit
In cold regions, the conventional wisdom used to be that heat pumps, such as those found in air conditioners, were ineffective and unusable for heating. However, heat pumps are inherently energy-efficient because they can generate heat using minimal energy. Recently, manufacturers have introduced low-ambient humidity heat pumps designed for cold climates, including cold climate air conditioners. When combined with high air-tightness and insulation improvements, these systems can significantly reduce heating energy consumption
solar cells for electricity generation
Solar cells, despite losing some of their momentum after a period of reduced feed-in tariff (FIT) prices set by power companies, remain a highly regarded residential facility. These devices harness clean electricity directly from sunlight, without relying on fossil fuels. Additionally, when combined with energy storage batteries, solar cells allow efficient self-consumption of generated electricity and serve as a backup during emergencies.
LED Lighting Fixtures
Compared to incandescent bulbs, LED bulbs consume 7 to 8 times less energy while providing the same brightness. This significant energy efficiency has led to rapid adoption. Additionally, LEDs don’t emit ultraviolet light, which attracts insects. As a result, you’ll have fewer insect-related issues. If you need lighting recommendations tailored to your room’s ambiance and purpose, feel free to consult with us if you need assistance.
Seismic retrofitting
The earthquake resistance standards required for housing have been raised twice, in 1981 and 2005. After conducting a seismic inspection, we will ensure that we are fully prepared for earthquakes.
earthquake-resistant walls
Usually, earthquake-resistant boards were used to add shear walls around the pillars of the load-bearing part of the second floor, and earthquake-resistant hardware was installed at the joints of the existing columns, beams, and bracing to improve seismic performance.
The diagrams below show an example of the renovation.

Re-roofing
It is possible to improve the earthquake resistance of houses built before the earthquake resistance upgrade by replacing the tile roofs with lighter materials such as metal roofs.
If you change from a tile roof to a metal roof, the weight of a single house can be reduced by more than 3,000 kg, which is said to be equivalent to the weight of an Asian elephant.

Installation of handrails
It’s a relatively inexpensive way to improve the safety of your home.
The shape and location will be set to suit the person who will use it , such as in the entrance, toilet, bathroom, or bedroom .
Eliminating steps
In old homes, there were almost always steps between the hallways and the rooms. This could cause people to trip when entering or exiting the room, so having a flat floor is a safe option.
Other effective ways to eliminate steps include installing a ramp on the approach, installing a ramp or step at the entrance frame, or adopting a flat entrance.
Changing doors to sliding doors
Swing doors require you to move your body when opening and closing. In addition, this type of opening and closing makes it difficult to create a large opening.
Sliding doors make opening and closing easier and also allow for a wider entrance.
adopt non-slip flooring
By changing slippery flooring materials such as tatami mats and tiles to non-slip materials, the risk of falls within the home can be reduced.
nursing care housing equipment installation
When a person’s physical functions decline and they require assistance, they may find it difficult to move around in a conventional space. We will suggest ways to make the space easier for both the user and the caregiver to use, and replace the home equipment with nursing care equipment, depending on the person’s physical condition.
