For houses, the standard final usable height per level is 2.60 meters. However, at an additional cost, it can also be executed up to a maximum of 3,4 meters, depending on the width of the profiles used. The internal staircase between levels is made of metal structure, a component part of the house. This is designed by the architect in collabouration with the structural engineer. For ground-floor houses, the staircase is usually made of double galvanized C-shaped metal profiles, 100 mm wide and 1.1 mm thick. The design is usually in the form of a ramp with a landing, to ease access between levels. The landing is a horizontal platform arranged on the course of a staircase for rest. The steps and risers are then covered with 15 mm OSB, and the final finishing, such as solid wood, ceramic tiles, marble, etc. will be applied over it. To increase efficiency, most houses with upstairs are designed with storage space under the staircase or even a dedicated space for a washing machine, boiler, etc. It is worth mentioning that the internal staircase is included in the price per square meter, valid for any predefined equipment variant from our offers, to which the final finishing is added at an additional cost according to preferences (solid wood, marble, etc.).
