When reading house plans, there are a lot of abbreviations used as there isn’t much space to correctly label everything on the diagrams. What is a WIR? It stands for Walk In Robe. It’s a larger type of wardrobe where you can physically walk into a little room that is usually designed around storing clothes.
Walk-in Wardrobes will often include an L shape or will be designed in a way that makes them hard to see into so that you can hide your clutter.
Which rooms usually contain a WIR / Walk-in Robe?
In modern Australian house plans, most will include a WIR in the master bedroom. The other smaller bedrooms will usually have sliding or pull-open doors. However, in larger homes, particular two-story homes you might find that all the bedrooms have their own WIR.
There’s not a whole lot else to say on this topic.
