I am always looking for techniques that are easy and fast for drawing one-point perspective interiors. Here is a window seat space that has a bookshelf and an art gallery area. A simple grid was set up using the steps that are outlined in my Exploring Perspective Hand Drawing, book, chapter 10, using a square grid formula
Note the two grids below. Each have a measured back wall with the vanishing point. The wall on the left has a grid that has been created with the diagonal guide line. This provides the proportions of the room in perspective where the objects appear to look larger as they come closer to the front. The first grid was sketched quickly with numbers noted on the back wall. The back wall was set up in a 1/2″ grid which is similar to an elevation wall. The second is an abbreviated grid version and has only the basic lines which are the key points that can be used when creating the drawing.
