We did a mixture of both with our builder G Developments.They have 10 external colours and 6 internal colours,so we mixed and matched some and picked tiles outside of the standard range at their supplier National Tiles.
The Colour Selection Stage can be the time when people get carried away and spend alot of money on extras,so having a budget is the key!Also with some builders it is the stage where you get a rude shock and find out simple inclusions like downlights, flyscreens,carpet or a dishwasher are not included in your build price.
Luckily for us our builder is fixed priced and turn-key-so that means everything is included and if we want something outside of the standard inclusions we pay extra,this is what we did with the tiles.
We have decided on a light grey tile for the main living areas that looks like timber ,which I am obsessed with!!,with pale grey walls and a white and grey kitchen... I plan to add touches of blues and Hampton Style furniture when we move in. Our main bathroom will be white and grey with the ensuite a more neutral sandy stone colour
Our plans are still with the architect...
We are still being patient...the drafting process does take 4-6 weeks...hopefully the next update will be about the plans being ready for Council!!
