The grey on the western wall looks dark and purplish on my monitor. It may come over as too imposing and monolithic on the southern face. If you're sticking with the grey palette then a warmer tone would suit the sandstone better. Does Dulux have a colour palette recommendation that includes your Berkshire White plus a grey? Check online or in store pamphlets. But, for such a big, expensive, and impactful paint job I would actually be tempted to get a colour consultant. You're not just repainting a loungeroom wall if it doesn't work!

Thanks for your reply. The roof is prominent. After a lighter and slightly warmer option for the wall. I like white but there are so many shades of white. Which one to pick that will give a little depth without being too creamy.

Unless you have the money to update everything else to better complement the bricks, painting them will give you a much more updated look. Over the past 18mths I’ve been working on the front and landscape of my current house, including painting the bricks and it has made the world of difference! I’ve attached a before and after photo! Good luck.

Can you post any more photos including the staircase, and how the room next to the staircase is accessed interesting extension not following in the traditional manner of the house, Always follow KISS, keep it simple S for the best result. You could add a traditional front door in black but I don't think it necessary as from what I can see in the photo is the entrance and door already have a lot of character. The lovely Picket will look less fussy if done in one colour quoting Taking the new build/old build divide quite literally, the existing cottage has been redefined as a crisp white entity. In a street of Heritage vernacular, where every architectural shift is picked out in a nuanced tone, this is a drastic departure in itself. Add to this the decision to present the new addition in solid black, and the radical nature of the build becomes apparent (Dulux low sheen black and Lexington white). http://www.wrightsonstewart.com.au/wilston-project
