The space looks a bit cold & clinical at the moment. Add sheer curtains to the window from ceiling to floor this wall Add some drama and also help to soften the look. I don't think the corrugated iron works use timber instead . A rug will better define the space perhaps with pops of colour like yellow , orange or red this will add some warmth. Prints on the wall , large pot plants side tables and floor lamps . In the billiard area it would look good to add a pendant lamp over the table you can buy ones specifically for billiard tables . More pops of colour also a couple of occasional chairs . You could also add more timber here to give more ambiance. Happy decorating .

If you really like the look of white and are happy with hosing it down, remember that exterior colours look much ch lighter and brighter and when on large scale. So you could also consider a light colour that has a bit of depth and 'muddiness' to it so it won't look too stark but will still effectively look white to the eye. Colours such as Dieskau quarter strength are beautiful. I'd steer away from cool grey undertones as they risk looking too stark and cold. Hope that helps!

Thanks Tilly, yes I think it'll be a really good exercise to think about how we live every day and what will support that. For example we had a BBQ on the weekend and the weather was quite cool, so my husband said how about a covered entertaining area to the rear of the house (north facing), but I'd rather have it open so the sun comes into the house every other day of the year! So we're investigating these fabric folding awnings... I might get us both to sit down and virtually go through our day to work out our ideal items. Thanks! Holly, thanks for sharing, some great ideas there. Yes I don't want a huge footprint, and survived for 10 years in a small Victorian terrace with a 'Euro' laundry behind fold-back cupboards in the bathroom and it never bothered me, so you've reminded me that I'd much rather that space devoted to more enjoyable areas! And keen on the versatility of a multi-purpose room, sounds like such a great approach, I work part-time from home plus my family is interstate so doubling as a guest bedroom would be perfect for us. Love the window bench with storage idea and yes I want an island bench that's clear of sinks etc. Wow those loft beds are amazing! Might pencil that in as an idea. Wonderful, thanks!

Our house is full of cavity sliders. Twice they were all (but one) replaced due to swelling/warping and rubbing against framework when opening and closing. Some made terrible noise whenever we opened or closed them. Hubby had a hunch they were poorly manufactured overseas and discovered that was the case. Builder sourced a local manufacturer and the whole lot, bar one, was replaced and we haven't had any further issues. The one door couldn't be replaced due to it's location - a wall would have had to be pulled down, just as co-design has described. This experience makes me think it may be a case of ensuring you purchase well manufactured doors for your climate and particular environment, and take into careful consideration the particular location they will be installed.
