We’ve just finished dealing with a kitchen design engineer. We want to improve our kitchen layout. We spend a lot of time in the kitchen and although its functional, it could be turned into something altogether more efficient and have a better ambience. So we have called is an expert. How can we ascertain whether this person knows what they are talking about, and whether what they are purposing is absolutely necessary, fits our body shapes and is in our interests rather than lining the pockets of the engineer?
