I recently decorated our beach condo on a budget. Items to consider are bowls or clear glass vases with found shells displayed. Sisal rug and woven baskets make a coastal feel. The baskets are great for storage as well. I used white light and linen drapes found at ikea.Because of small size of room, i have glass tables to help maximze space. I am adding shutters found at a flea market as headboard for guest bedroom this year. I found many useful items from community sales. I frequent local beach decor shops some pricey to get ideas for arranging and adding items. I would put couch so can look out window to garden. Put it floating in the center of the room, Tv on wall. Two chairs sort of where they are now in photo. Small table and chairs located near door and kitchen. Looks like not much space there but look at ikea furniture as it is for small spaces. One ikea table is shown to be against wall and then pulls out to enlarge, it might work for you.

Photos would help

Thank you all for your lovely comments. The family was quite happy when they came home after the installation and styling. My biggest reward is how the family now can enjoy a better way of living.

I wouldn’t hesitate to paint the whole lot white ( kitchen included) it will be quicker and easier than trying to lighten the colour of the pine and will look so much brighter and fresher than you can even imagine. The boards will still give the space a lot of character but painting it white will bring it up to date and add a lot of value. Definitely more appropriate for a beach property.
