Hi Kristy, You can either get a custom made freestanding cabinet which will completely fill the space, we do this sort of solution, or get a pre fab freestanding rack of shelving from somewhere like Howards Storage or hardware stores

am i correct in understanding that this space has no windows and will be a wiw and entry from the living areas to the master bedroom? do you plan to have enclosed storage (wardrobes with doors) or open shelves, what do you need to store eg clothes for how many people, lots of ball gowns and multiple shoes or mostly jeans and shirts, clothes for various seasons, or only tropical as well as christmas trees and suitcase and secret stuff...start with what you need to store and work backwards and excellent lighting (daylight, skylight or electrical) will make all the difference for success

Traditionally if they were painted (not stained timber) they would have been painted to match the trim colour in a semi-gloss or gloss paint. They would never have been painted the same as the wall paint as the wall finish (probably a low-sheen) is not suited to the wear that doors get, and is harder to clean than a semi-gloss.

You should give Flexirobes a call. While they are based in Cambellfield their service area is wide. Maybe visit their showroom with your measurements to get an idea of how they can help. I have only ever had good prices and professional service from Flexirobes. https://www.flexirobes.com.au/wardrobes-melbourne.htm Best of luck, Dr Retro of Dr Retro House Calls
