The long black one is the back garden door way.The smaller one on the same wall is the door way leading to extension;s corridor. The black square at the front is the door way to enter the room. The white squares are the supportive pillars for the back wall and the long one is the chimney breast. Thank you for your answer :)

To begin designing a kitchen you draw the entire space to scale on a computer or on paper. Then place your appliances sink table chairs etc on the floor plan. You do this to understand if your ideas can even work the way you envision them. I would recommend using a kitchen designer. Working by yourselves, the kitchen design would be limited by your experience and abilities, and starting the process in the wrong order does not bode well. After the kitchen is designed then have several contractors come to give you bids and their input. This will save their time and make the bids lower and more accurate. After you have potential floor plans and have thought things through, this is when advice from Houzzers can be helpful. When the job is not completely thought out advice on Houzz can be dangerous. You will be encouraged to make decisions also not thought out and coments will seem valid no matter who is making them.

to add, this was original layout. I was worried kitchen would not get much light in mornings. the house is actually Northeast facing. what you prefer it any other options.

What colour scheme for living area to match with carbon coloured kitchen with dark wood on upper presses
