This is a very interesting discussion OP and it's something I think about frequently.
We live in a modestly scaled 180 year old farmhouse. It was totally derelict & without a roof or doors or windows when we bought it in our v early 30s & we've spent a long time slowly renovating it as funds allowed.
The house itself has a beautiful calm, peaceful feeling & is filled with light.
When we first moved in 20 years ago we painted it all white. We used farrow & ball matt soft white & it gave a beautiful chalky finish which we adored.
Over the years we've redone all the rooms & we've added colour to them all. Mostly soft muted shades but in some rooms stronger colours. All still f&b matt finish.
We have books in every room & many bookcases as reading is an obsession for us. And we have a lot of artwork hanging- all originals. We travel a lot & have small objects bought in different places - I bought by small ceramics in Sweden from a the design museum, made by a local artist. We have antique silver candlesticks from Italy, an antique magnifying glass from Paris etc these things have a special significance to us and when i look at them they bring joy to my heart & bring me back to the day / trip when they were bought. None of them are generic 'souvenirs' from holiday destinations (not that that matters to me if that's what anyone else loves & collects)
I, personally, could not live in a minimalist grey / white / beige modern new build. I see why they appeal but it's just not for us.
Our furniture is a mix of inherited pieces, antiques, ikea & custom made. We have things from both of our grandparents in our house - so great grandparents for our dc & a couple of things are valuable so we'd never ever sell & will pass them to our dc. I really love that continuity.
Some days I think I'd like a bigger kitchen but the rest of the house is a good size so we're mainly v content with what we've got.
