I do love a good snoop around people's houses - something worth remembering if you ever invite me in, although I will always respect your privacy by not actually divulging what I find ;-) - so this is an event that really appeals to me. And whatever you want to say about the opportunity to examine the architectural detailing or admire the historic fabric of a building, I'm damn sure a lot of you love snooping too, you're just too polite to admit it.
So what will there be to see in Deptford?
There's enough to keep you busy for a whole day in Deptford, and if you aren't from round these parts, I reckon you'll get a good introduction to our neighbourhood by coming down on Saturday 21st September.
Start with a trip to the top of the Seager Distillery Tower - a building which it's definitely preferable to be in looking out, rather than the other way round. I went up it last year and the views are stunning - you can orient yourself with views north to the river, following the route of the Creek, or look south towards the rest of the borough. Be warned space is limited at the top of the tower and you may have to queue.
Once you've descended, you may wish to head over to Deptford New Town where you'll find the pocket-sized Connearn Studio in Friendly Street. I've not been to this one, and from the picture on the website it looks like it won't keep you amused for long - but the walk is a pleasant one, especially if you go through the park and pass by the Stephen Lawrence Centre. Just try and ignore the ugly block of houses they built next to it (replacing the ugly houses that were there before). You can come back along Brookmill Road past Mereton Mansions, or go the other way to pass Wellbeloved's butchers on the bottom of Tanner's Hill, in a row of Deptford's oldest buildings.
From there I would recommend a wander down our fabulous high street and through the market (not forgetting the huge second-hand stalls outside the Albany) to Tidemill Academy and the Deptford Lounge, to dig out the substance behind the bling. You might want to linger in the library for a while, browse a few books or have a coffee.
If you like your coffee super-charged, be sure to stop off at the Waiting Room to get your caffeine fix, and a falafel wrap or veggie burger with super hot sauce to keep up you sustained for the afternoon. Any visiting vegans will be happy to discover this place, which serves vegan-friendly fare without making a fuss about it.
Alternatively if the Waiting Room is too crowded - or you want something a bit more substantial for your lunch - Deli X a few doors down is another great option. If you want to eat on the move, or it's too nice to go indoors, I recommend filling up on fresh salt-cod fishcakes or souse from In a Pikkle or try the jerk chicken with rice and peas from the neighbouring stall. Both are in Douglas Square in the middle of the market.
From here, keep walking towards the river for two more very interesting Open House experiences. Convoys Wharf site is well worth a visit just to get an idea of its vast scale and the glorious riverside vistas it has kept to itself all these years.
You're too late to see any of the remaining underground structures - they are still there but covered up for now - but you will be able to venture inside the Olympia boat-building shed with its distinctive curved roof and lovely internal iron structure.
According to the Open House listing, there will be displays showing Hutchison Whampoa's redevelopment proposals. It's more than possible they will wheel out the famous groundscape model of the scheme although perhaps they'll also show the little polystyrene blocks (above) which are supposed to show the building density and heights.
Right next door to the site is the historic Master Shipwrights House, which will be open to the public on both days - a rare chance to see this beautiful building. I visited a few years ago during Open House and was mightily impressed - you can read about it here. Normally this house is only visible when glimpsed from the river on a Thames Clipper - don't miss the chance to explore behind the big steel gates.
What's more, I've got it on good authority that there's going to be some very interesting events taking place here over the course of the weekend - of which, stay tuned for more details in due course.
While you are down Watergate Street, it's well worth popping into the Dog & Bell for a pint or two of the best-kept (and by far the cheapest) ale in Deptford. Have a game of bar billiards or sit out in the garden at the back - it's a real old-fashioned boozer of the best kind.
If you're visiting from outside the 'ford, do take the opportunity to explore our lovely little corner of SE London to the full. Every one of these is only a stone's throw from the high street.
Deptford Creek - tide half in, half out. Look out for herons and swans, or watch the DLR trains rattling over the bridge.
St Paul's, Deptford - a Baroque beauty with a bit of guerrilla gardening on the adjoining green space. The grass circle marks the size of the access shaft that Thames Water wants to dig for its supersewer.
The Laban Centre on Creekside was designed by Herzog & de Meuron and won the Stirling Prize for architecture in 2003. Sadly it's not part of Open House London, which is a shame. But they do have monthly architecture tours you can book at £12 a head - and it has a very pleasant garden if you want to picnic.
Finally, if St Nick's church in Deptford Green is open, it's worth taking a look inside at the Grinling Gibbons woodcarvings. But even if you can't get inside, you might want to walk past just to look at the famous skull & crossbones sculptures atop the two gateposts.
Other eating and drinking highlights close by are the rotis at Chaconia, grilled pork noodles or banh mi at Panda Panda, cocktails out of teacups with cheese straws in the living room of the painfully hip Little Nan's Bar, a wide range of ales and reliably top-quality dinners at the Royal Albert, and if you are prepared to walk that bit further, there's the small-but-perfectly-formed London Particular, another place for great quality grub, top coffee and fantastic cakes.
