I'd google restaurants in water front locations like St Kilda, Noosa, Bondi, Port Douglas (or Nantucket, Muskoka or Hamptons) and see who has a look that's similar to what your after. Then we could help with more focussed suggestions. Coastal can have many versions. Have you finalised wall, ceiling and floor finishes?

I couldn't define the colour. I may need to view on PC screen. I think the exterior is nice, I'm just not certain what gives a coastal/beachy look. Maybe some natural elements like stone or timber? idk! Hopefully others will have better ideas.

Hello, if you wish to get free advice from a professional interior designer, have a look at Milray Park Online Design Bar. Our Design Team would be more than happy to help you find the perfect colour scheme :)

Hey Ali, are you asking for a particular reason? If you just want the popular 2020 colours, you’ll get a different response than if you’re looking for the most appealing colours because you’re hoping to sell. Again, an older style house might elicit different answers than a cutting edge apartment. And surroundings, temperate/tropical or north facing / east facing for example also will affect the suggestions, as will whether you’re thinking wall, roof or cabinet colours and any current scheme. So, after that ramble, I’d say add some detail and the lovely Houzz people will be sure to help
