Create a rectangle frame. The window frame should be 4/10 meter by 4/10 meter. You don't have to bother about concealing the hole because glass was not utilized in the Anglo-Saxon culture. Take pride in the Anglo-Saxon-style house you've built. Include your email address if you want to be notified when this question is answered.

Anglo-Saxon dwellings were rectangular wooden cottages with straw-thatched roofs. Each family residence featured one room with a fireplace for cooking, heating, and lighting. The dwellings were created to take use of as much heat and light as possible. There was no such thing as indoor plumbing in those days!
The rooms had open beams supporting a canvas roof called a "tent." The walls were made of wattle and daub: split willow branches with mud used as a binding agent. The floors were made of wood shingles or earth. Windows were mostly small openings in the wall for ventilation on hot days or when it snowed. Doors were usually made of wood too. They opened outwards from the house onto a porch or yard.
There was only one bathroom in the house. It was located outside in what we would now call a "yard" or "porch". This area was used for storage, but it also provided a place where families could go during dinner time or after a long day's work.
Families would eat their meals around a table that sat in the center of the room. Men would eat first since they worked outside the home, then women followed. Children ate last because there weren't any other choices! But even children liked to have food served to them so someone would often offer them a bite before they went to bed.
Windows had wooden shutters fastened by an iron bar, but they were rarely glazed throughout the 11th and 12th centuries. By the 13th century, a king or powerful baron would have "white (greenish) glass" in some of his windows, and glazed windows were popular by the 14th century. But most castles and monasteries built during this time were not equipped with glass windows.
The first known use of glass for windows comes from China around A.D. 400. It was not used in Europe until about A.D. 1000, when it was introduced into Germany by missionaries or traders. It wasn't until many years later that it began to appear in larger quantities. During the 11th century, almost all windows were made of wood; by the 13th century, glass had been added to some of these windows. By the early 15th century, Venice alone was importing more than $100,000 worth of glass each year. The price of glass dropped dramatically after this time, so it is likely that much of this glass was re-exported back to Europe.
Medieval houses did have small openings called "windows" which allowed light in and air out. But these openings were usually covered by wooden shutters. Even if they weren't covered by shutters, there was very little a person could see through them. There were no glass panels inside walls as we know them today - everything was open to view by anyone who wanted to look.
