Express public transport to central London - easy access to DLR Lewisham and Docklands - frequent buses in Eltham Road [a new bus lane going in now]. Fast connection by car to the UK Motorway network A20 M25 South Circ. etc. The pretty village of Eynesford with its trad pubs and river is only 40mins away by car - the very heart of Kent.
Local shops are in abudance esp. Burnt Ash Road [near Lee Station] - also Sainsbury's supermarket at Lee Green. The private housing in SE12 is of a high standard, much of it built in the immediate prewar years 1935-1937 - semis and detached [Scotdale types including a few Mock Tudors]. Older housing stock, Georgian, Victorian and Edwardian are also available to rent or buy in SE12.
Most of the SE12 area is above the flood plains of the local rivers. Days out on foot are within easy reach - Blackheath Village, Blackheath and on, over the top and down into Greenwich [Royal] Park passing the statue of King George IIIs most famous general, Wolffe and on down the steep slope passing along the Greenwich meridian [today tomorrow etc] and into Greenwich.
If you cannot manage the slog back [3.5 miles] there's always the DLR from Cutty Sark to Lewisham and then a bus back to Lee. The SE12 tribe have accesss to some of the South East's finest restaurants - Chinese, Indian, Greek [Troy Taverna Lee Road], Italian - most are clustered in and around Blackheath Village.
The finest seafood restaurant in the South East is the Villa Mora in Lee Road [Lee Green]. It is run by Portugese folk [our oldest allies] who specialise in seafood dishes. The portions are vast, so ignore the bread.
SE12 has an abundance of trees - the Eltham Road from Lee Green is a tree lined straight run of fabulous vision, esp. in high summer - "this green and pleasant land". The front gardens of the houses of SE12 are an abundance of hard work and eyefuls of pure pleasure. There are allotments and sports clubs and lots and lots of open spaces. I have lived in SE12 since c1989. I am a veteran.
