The Matsuya tower has an open well hole structure all the way to the top of the premises.
The common corridor is open style, and we have installed ventilation to the fire fighter's passage,too.
We built a lot of corner rooms and the rooms with a ventilation window.
Each room is very well ventilated so it will be very comfortable even without air conditioning and its very eco-friendly to prevent the global warming.
And we invented that the lower part of the balcony handrails for better ventilation.
The entrance hall of the each residence is designed to not to be able to see inside of the room, so you can keep it open to have fresh air anytime.
