度々申し訳ありません。また添削をお願いいたします(><;)
This Third floor sells daily necessities. I’ll show you how third floor is based on plan. There are seven departments and is (an? The?) elevators. On right side from an entrance, there are two departments, Lamps and Toys, back to front.(「 奥からLamps, Toys という順番で」としたいです。) Right side of a wall, there are the Elevators. As you enter the shop, you’ll find the Furniture department in front of you. It is middle of the shop. Behind it, there is the Carpets department, next to the Lamps department. On the left side from the entrance, there are three departments, Kitchen Equipment, Bath shop equipment and Electrical Appliances back to front.
