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!

Thank you for your comments, I do agreed with your comments of considering not rendering as we don't dislike the brick, we just thought rendering would bring it up to a more modern feel. We have an established tropical garden already....so would play on that with the timber and see what we think. Currently, the roof is manor red, but liking the Ironstone better than the current. Thanks again

Good morning Ish Shah, Great looking house ;-) I can help you choose exterior colours to tie in with with current choices. Head over to my website and send me an email and we can chat and exchange info. LClick on link to Website

Dulux has about 4800 colours available to design professionals, and only about 10% of these are available as sample chips from your hardware store. There are so many subtleties and nuances with colours that are lost with digital images I would not want to make a recommendation online. The only way to make colour selections is to get paint colour swatches, stick them up, and observe them in different light conditions. Your perception and appreciation of them will change at various times of the day. I would not choose any grey for your home as grey is the mission brown of the future. I would choose one of the colours that is appropriate for the period of your home that works with the white window frames and roof tiles. Best of luck, Dr Retro of Dr Retro House Calls
