We're in the middle of an extension and need to order windows & bifolds. We want anthracite grey aluminium bifold doors (they're not huge. Only 3 glass panels). The back of the house isn't flush, so the bifolds and the kitchen window are not next to each other. We have a huge kitchen window which is further out into the garden. Obviously grey bifolds are very popular, but what do people then do for kitchen windows? Grey window frames seems a bit strange - they would generally be white, wouldn't they? - but I don't want the colours to be mismatched. What have other people done, or what do you think is the right way to do this? Thanks!
