The chairs are a good match. Leather is probably best, great for kids' spills and accidents, but any fabric will do. Not sure on purple with green - those two colours together clash a bit for me. The green kitchen looks great, and I'm a fan of dark wood. The only thing throwing it off at the moment is the yellowish coloured walls. If they were repainted a soft white, this would make the green and the dark wood really pop, giving you a fresh and sophisticated, calm look which I think would work well. You could then upholster in a green to match the kitchen which would look appealing. Finish it off by some fresh white flowers as accents in the room to draw the eye and you've got a beautifully transformed space with a fabulous feature dining area :)

I would embrace the element, but I would get rid of the wood chips. I'm thinking back fist sized river rocks. Then I would get a tallish flowering tropical such as hibiscus and add a few ivy plants to grow between the rocks. Additionally, a small water feature might be nice. For me, the bigger problem with the entryway is the door. You have an obviously contemporary home, yet you have a -very- traditional door. I would want a wood door with some sort of art glass element in it. The wood would of course need to be stained to match the existing woodwork. The door will be some big bucks, but it would remain regardless of flooring changes. These two doors are not specific recommendations, but examples of the type of entry door I have in mind. Best wishes!

I'm guessing you are from NZ (kiwi) :) The handy sanders did our floors - http://www.handysanders.co.nz/. They did an AWESOME job and are reasonable priced. I would definitely recommend.

I grew up with these panel doors and remember the glorious day they were replaced by a curtain. So if you are open to the idea, for ease of use, least effort and cost that's a simple fix that your daughter may want herself. The top cabinet doors can be considered a cornice for the drapes, and can be upholstered, maybe in the same fabric as her window curtains, and a simple drape with coordinating stripe on the bottom. Search "upholstered doors" on Houzz, and you will see ideas for nailhead trim, tufting, etc as well. You may also be able to add thin trim molding in a custom design to make them special. Good luck!
