Thanks guys for all your input. I am loving that Emily Henderson room and that contemporary/mid modern century room! I am after a light and bright space and I do love the greige trend - just not sure how I can do this considering all the beige tile and cabinetry in the kitchen. Can I transition from cool undetone to warm in an adjoining room?

The vintage green tiles in the first picture are lovely. The darker ones below with the bevelled edges are just so wrong in the setting shown. I am also a lover of green but you have to get the right tone and keep the shape as smooth and flat as possible. I am a big believer in having just one standout element of design in a tile - either its unusual in shape with a matt finish or a special colour with no fussy edges.

I think if you replace front door and glass panels as well as the old fashioned lights with something more contemporary it will make a huge improvement. I'd also remove the ironwork and as you cannot re-glaze place some pots and plants on the sides of the large windows to draw the eye away from all the green cross pieces on the windows. Eventually paint the gutters fascia in a light grey/green.

Have a good read of this article. http://www.tilewizards.com.au/installing-tile-over-tile-pros-and-cons/. Beware that if tiling over tiles your floor will increase in height of tile and adhesive cement. Therefore the bottom of your doors will need to be adjusted because they might not open. (Carpenter needs to take door off the hinges and cut off the bottom of door that is the wrong height). Your skirting boards will need to be removed, then re installed. If you having aluminium sliding doors, then the new height of tile may look silly. The height of the tiled floor may not be even with your bamboo floor, and cause a tripping hazard. Also if the floor underneath your existing tiles is wood, it might not be strong enough to take the weight of two lots of tiles. Trying to save money on not taking up existing tiles, may cause extra costs in other ways.
