After much thoughts I've decided to bite the bullet and put my savings (+some borrowing) into a kitchen extension. Obviously, it's a significant sum of money and want to get it right. Existing and proposed architect drawings posted below. But I am thinking, instead of standard sliding doors, we can have a picture window that end and patio doors to the side as the seating area we use most in the garden is next to the sliding doors from the living room. I am also thinking it will give us more seating in the kitchen and more flexibility on where to place a dining table. Any thought?
