Cabinet boxes for kitchen

I've always thought of using cabinet boxes like the photo below for our kitchen. By using cabinet boxes, I think it would be more flexible for us to change the old cabinet for a fresher look in our flat than waiting to save a huge budget (paying for remodeling could cost as much as our flat :p) for major overhaul.
