Detached and semi-detached houses dominate here, the kind with gravel drives and hedges trimmed into straight lines, and the population count tells you most of the story before you've read a single grade: this is a small, settled pocket rather than a village with a bustling centre of its own. Castle Green sits inside Surrey Heath, and the money shows — average incomes and deprivation figures both place it at the very top of the national scale, decile 10 on both counts, which in plain terms means this is one of the more comfortable corners of the country to call home. The practical picture matches that impression. Median age nudges toward 48, older than the national average, and the property mix — freehold houses overwhelmingly, detached and semi-detached running neck and neck, barely any flats — reads as a place for people who've already done the moving-around phase of life and are settling in. A house here carries a premium: the local median price sits comfortably above the regional figure, and even against pricey Surrey Heath as a whole, homes here go for around 11% more. St Lawrence CofE Primary School serves the immediate area, an academy converter that gives families a straightforward local option without needing to look elsewhere. Public transport is thin — just a couple of stops recorded locally — so this reads as car-dependent territory, the kind of place where the drive to the station is part of the daily rhythm rather than a walk to one. Green space runs a little below the regional average per head, which is worth noting given the leafy reputation such postcodes often carry, though the environment grade still comes back as one of the strongest marks on the whole scorecard. Broadband is solid rather than exceptional, with two-thirds of the area on full fibre — enough for home working without any drama. The crime figures are genuinely low in absolute terms, just a handful of incidents across the year, and the safety grade reflects that; but look at the breakdown and violence and sexual offences make up close to a third of what's recorded, an odd, out-of-step note in a place where everything else — affordability, environment, schools — reads calm and settled. With numbers this small a single case can swing the percentages, so it's worth treating as a data quirk rather than a pattern, though it's the one figure that doesn't fit the rest of the picture. Taken together, this is a place for people who've already got their transport sorted — a car, most likely, or tolerance for a drive to the nearest station — and who value quiet, greenery, and space over having shops and nightlife on the doorstep. Prices ask a premium for that, and buyers should go in with eyes open about the trade-off between calm and convenience.
