Announcement of the renewal of the staircase kit specialty site "www.arke.jp"

Perfect for renovations and remodeling! Why not create a stylish space with loft stairs?

Lofts can utilize the dead space of attics, creating additional space beyond the actual floor area. This is especially useful in compact lots where expanding the house further is not possible; having a loft can be very beneficial. While a staircase is essential for such a loft, don't you have the image that "loft stairs = moving a ladder is difficult or dangerous"? The loft stairs we propose are designed with safety and comfort based on ergonomic principles, and since they are "installable," they are suitable for retrofitting in renovations and remodels. 【Features】 ■ Achieves space-saving without compromising the lifting function ■ Safe and secure design based on ergonomic principles ■ Retrofitting design suitable for renovations and remodels ■ Appropriate for loft stairs ★ For inquiries by phone, please call → TEL: 06-6584-8422 * When calling, please mention "Ipros" as a reference.
