What a great look you are creating in your new kitchen with all the mix of materials. I just love slate floors. I would suggest you need a much earthier colour in the stone for your benchtops, in regard to the latte tones, something like the organic patterned Clamshell or Shitake by Caesarstone would be great. If you are going with real granite or marble, something like River White granite, which is still fairly white and light in colour, but has some beautiful, organic markings in it. Make sure you view a larger piece before you make any decisions. Good luck!

I am thinking about replacing these chairs with wood the same color as the table top. The base of the table and the apron are black. How would that look? I am thinking of upholstered seats with some black in the fabric to pick up the black in the table and the rug. I am just tired of the black chairs....help.!

I wouldn't go those dark laminate kitchen cupboards. I have the exact same and I absolutely loathe them now. I use to love the darker colours but now I wish I had just done them white, light gray or even the dark blue (although dark blue worries me a little too!). That dark laminate brown is such an absolute pain to keep clean. They show up every mark. I like your stone bench tops though but would look at other options to create the look you're hoping for with the joins and waterfall benches etc. Goodluck with it all!

Actually I think you can have whatever style cabinetry you want so long as the colour scheme is the same, consistant colours are what helps create the 'seamless flow' from old to new. We did the same kind of renovation 2 years ago - a huge extension onto our 1900's cottage and the front hallway (in the original house) joins the new hallway so flow was very important as we did not want it to look like the old house stopped and the new house began. But honestly the cabinetry can be more modern if you prefer, and completely different from your existing, as from my experience to create the perfect flow between the old and the new the most important details are: 1) Paint and colour scheme: If you want the old house to connect well with the new extension make sure you repaint the walls, ceilings and cabinetry in the original part (at least the hallway and areas that connect with the new) the same colour as you paint in the new extension and keep the colour scheme very similar between the old and new. 2) Flooring: We had solid hardwood flooring in the original house but unfortunately is was so badly water damaged and patched throughout so couldnt be saved, so we installed the same wide-panel reclaimed-look oak flooring that we were using in the extension - essential as the old and new hallways joined. 3) Doors: Try and find doors as close as possible to the ones you already have. We had some difficulty with this as ours were solid timber and had 5 horizontal panels but in the end we managed to find one supplier that had similar and with so many doors in the new extension it really helps create a more seamless look 4) Wall panelling (if applicable): We had waist high panelling throughout the original house and our builder copied this throughout the extension (his suggestion). Couldnt be happier with the result and it definately wouldnt have looked right if the panelling stopped suddenly where the new house began 5) Consistant ceiling height: Really important when blending old with new, make sure you keep ceiling heights the same at the point where the old meets the new - or go much higher, this also works. But dont go just slightly higher or lower! Other than that there is no need to try and replicate other period details like cabinetry and cornices. Love and celebrate the original part of your home that has the quirks, ornate ceilings, fireplaces etc and let the new extension compliment without trying to compete
