Building First home

Cant give recommendations in general with that builder, but during the colour selection, this is honestly personal preference. Depends on the style you want. Do you want modern, coastal, classical, contemporary etc...? - if so, do you want to do a lot of colour matching, i.e same colour handles on all doors / cabinets... think about everything before you go.

Do you want pops of colours in your bathroom, etc...
Think about patterns too, so many people go and select a colour for tiles, but forget that they also need to decide between things like Herringbone, Subway, vertical stack... etc... patterns. I did my selections last October, i actually cant remember if colour was separate to internal selections.... was so much to decide upon, but its very exciting and fun!

Bricks i cant help with sorry, we went rendered hebel.
