Step 1. We draw two rectangles, top is slightly lower than the lower.
Step 2. We draw a bevel of lateral faces of a roof and additional decorative lines.
Step 3. We erase horizontal lateral straight lines from a rectangle, then we draw a door and windows.
Step 4. We draw a lattice at windows, from above there will be at us an attic.
Step 5. We draw a window on an attic and on it it is possible to finish but who wants to draw all house, we continue. We draw parallel lines on roofs.
Step 6. We draw a tile. Let's begin with the lowermost row. We plan the middle of the house and we draw a horizontal straight line in the very first lower row. Then we draw to the left, thus every time more bias of a straight line is done to the right, then we draw to the right, doing, the farther, the line bias is more to the left. Now we pass to the second row from below. Each straight line we draw it is drawn on the middle between each tile of the first row, do not forget, than closer to lateral face, the line has to be more inclined by that in other party. We continue to do so to the most top row inclusive. Then we draw patterns and on each side and on an attic roof. I drew wavy lines with circles, you can think up the pattern, it not essentially.
Step 7. Here so the final version of the house looks.
