We moved last year from a house with an East facing back garden (where we'd lived for years) to one where the back faces SSW.
In the first house, the garden was fairly long, so we had set up a seating area at the end of the garden, where we got most sun. The garden near the house was in constant, deep shadow. The bit at the back got sun until about teatime in midsummer, but much earlier in winter. We used the garden fairly rarely - the trek down to the other end of garden was more offputting than you'd think and we found we never just wandered out casually. There was full sun at the front of the house from midday, but we were never the sort for sitting in the front garden (although a fair few of the neighbours set up chairs or benches outside their front doors).
By contrast, in the new garden, the seating area is directly at the back of the house and has the sun all day (until about 9pm). We put in patio doors in both the kitchen and sittingroom that open directly onto the garden, and you find yourself casually wandering out on any fine day with your tea and toast or glass of wine, a beer, a coffee etc.
I'd describe it as a very significant improvement in quality of life.
Having said that, I know people who paid a premium for a south facing garden in a new estate, only to find the house behind was so elevated that the back fence was double-height and there is no sun in their garden, ever. So check the site map for hills!
