You have a great opportunity to go eclectic. So using very modern and colourful elements for the kitchen - modern storage cannisters, a vase, lights, toaster, even mixer, you start to introduce shocks of colour and shape that jar with the expectations in a traditional kitchen. In this image see how the chairs just add a touch of cheek to cheer up the kitchen...

I had purchased hafele hob 10 months back... I got it serviced 6 times... Now i requested for replacement with new one... Still they have not attended my request...

okay thank you sir I was looking into the future just checking options .

And you can have different designs in different rooms but there should ideally be some elements which should be the same throughout. For instance, I like to use the same wood veneer finish throughout, but the designs could be different in each room. Or like Cornerstone Design says, the children's room alone can be different. I prefer not to make the children's room something that is too 'kiddie', so I opt for a more classic design for the Master bedroom, but keep it simpler and similar for the others, with some small differences. Sometimes clients feel cheated if they don't get something different for each room, so it is the job of the designer to convince them
