Thank you for your suggestion! I will definitely consider it, however, the back wall where the opening was placed is I think where the plumbing for the sink is located.

Contact a local architect to assist you.

I am not real familiar with the metric system, but a lot that is 2 meters wide and 6 meters long (6.56168 feet by 19.685 feet) does not seem very big.

Yes, we are aware of that, that is why we are hoping to have suggestions for the best layout we could possibly have. We are also planning to consult an architect after the pandemics ends, nonetheless, thank you!

I don't think 2m width is enough to have a decent bedroom. For the US people that is a little more than 6.5 ft.

It sees without doing any work on the rest of the house you will spending money on something less than useful.

@ lyfia, European homes are smaller on average than U.S. homes. The United Kingdom as a whole averages 800 sq feet per home, or 74.32 sq meters. If these add-on rooms are for children, they only need to hold a twin size bed and a wardrobe. She intends to live in this house for the rest of her life. If what @margaret needs is bedrooms for 2 children, how can this be less than useful?

@lyfia I understand that the lot size of the addition is smaller, but as what @mindshift said it is for 2 children who are growing up and needs and therefore wants to be somehow have their own place in the house. Nonetheless, I appreciate your concern. Thank you so much, God bless you both! :)

Yes homes in parts of Europe are smaller but that size is not going to be a bedroom even in a tiny house .

Yes, I know that it is quite small but we are planning to have atleast 2 by 3 meter additonal bedrooms; which why I am asking for an advice. Nonetheless, your comment is very much appreciated, thank you!
