About 12 The Walled Garden
12 The Walled Garden is a four-bedroom property in Tewin, Welwyn, Welwyn (AL6 0BZ). It has council tax band G.
Held since December 2008 — that's 17 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. One planning record on file: an extension approved in 2004. Past consents include an extension and a conservatory, meaningful when judging how the property has evolved. Across 2000–2008, sale prices on this property compounded at 2% per year.
