Kitchen room project

Hello! 

I want to make this room more comfortable for my parents in their summer house! I need your help with this! A project is needed for the kitchen room in the summer house. This is an existing room, so the dimensions are fixed, and we need to work with the dimensions that are available. The furniture needs to be arranged with the specified dimensions, but of course, in a way that is convenient for the residents.  After the layout of all items is approved, we will need connections for the electricians to implement all the connections directly. There should be a sink (round), a built-in oven, a gas cooktop, and a freestanding refrigerator preferably 700-750mm wide. A table, osmosis connection, underfloor heating.  A gas heating boiler is already installed. The sewage is diverted to the opposite wall from it.
