If there are any home improvement professionals specialized on kitchen extension planning out there then please help me out. I want to correlate the main work surfaces, (my fridge/freezer), the cooker and the sink, these zones should make a triangle and also get a kitchen bench seating. But the sides of my work triangle is not equal in length and they are a bit longer than 4.5m (4500mm) approx. I want to keep the overall design simple and make sure it works for my family too. Please tell me how do I go about the layout and the measurement?
