i love African nature and incorporating it in designs too. The colourful one isn't my taste, but the black and white are great

Amar, can you measure the rooms again in Meters , marking doors and windows You could sell your old kitchen and appliances which would also be removed at no cost to you. Would you reconsider using the existing free standing cooker and Range hood this would save a lot of money, the cooker could be replaced at a later date? Once you have the measurements you could take them to a Bunnings for them to quote and do a floor plan at no cost to you, once you have this you can ask others to quote. Keep in mind that drawers cost more than a simply cabinet, and your choice of door profile/style will effect the price.

Herringbone pattern has lots of cuts or jagged edge. Better to run it between walls and finish at a defined edge. If shelves aren’t hitting range then you need to go to ceiling, it won’t be cheap. Alternatively put a stacked tile border around the herringbone and stay under the rangehood and continue the border as the rest of the splashback along benches Use silver colored grout not white or it will look grubby. Nat tiles cheap tiles are not particularly uniform. You will find slight size and thickness variation with all cheap tiles.

Thanks Kate. In the first photo at top of this thread is our existing house, with the load bearing walls being the solid lines on outside. We now have a tweaked plan version 3 below- but still not convinced yet... We were keen to make bedroom 2 and 3 a bit bigger as the kids will use their room more than we will lol! What we are looking to do would be to add on one end (the lounge and master) and widen Bed 2 a bit as it is quite narrow. We would like to improve the kitchen and dining and entrance but getting a bit stuck here. We are trying use the space we have got without changing too much to save in cost but this area is important to us and would be used probably more than the lounge, which is quite big in comparison. The alfresco would be a bonus. It is more so that we want to include a back door leading outside as otherwise people would need to go back out the front entry or use the laundry door which is pokey and small. If we could revamp the kitchen and dining in a creative way, so the dining doesn't look so small compared to the lounge that would be good. The idea would be to see how big/far we can go, then ask a builder to quote and if too expensive, scale it right back...We have ruled out going up as we thought this too expensive?
