In designing this plan, we have tried to position the windows so that we have at least 2 load-bearing walls. That is, the windows are set to one side to minimize damage to the surrounding walls. Also, the wall on the LCD side can expand And replace the bedroom window and make the hall bigger. But we have now created this plan based on the current building and the change of the interior walls. Also, in the case of stairs, we have considered its axis diagonally to take up less space And more spaces can be used more.
