Getting high on South East London's crowning glories

When the city's too hot - head for the hilltops of south-east London. Head for Dawson Heights!

So I said I was going to change, and write lots of positive, morale-lifting stuff in 2019. Of course that was a New Year's resolution and those things have to be broken.  But this one starts off on a very positive note: it is about South East London, which – as a resident of a dreary SW postcode for far too long, has always seemed to me to be the infinitely more exciting, romantic, creative and simply all-round decent half of south London as whole.

I'm not going top justify that statement - but this piece and many that have gone before, and more that will follow - tell you that story.

It was about 20 years ago, strolling through Brockwell Park late on a rare brilliant January day, sun low in the western sky, dramatically floodlighting the hills above Dulwich and beyond.

There, right at the highest point, were twin, golden, towers rising out of a pair of stepped buildings, dominating the landscape beneath them like the fortifications of some Italian hill-town built by 20th century modernists rather than medieval masons.

I'd been vaguely aware of these buildings for a long time, and became increasingly fascinated. What was this place: the headquarters of some sinister intelligence organistion, looking down on us all, monitoring us from its multiple elevations?

Of course it took only one search to find out that this was social housing from the golden age: an example of truly progressive policy of the 1960s, on the part of Southwark Council. Even the name of this council estate - Dawson's Heights - has a romantic ring. It could be the title of a thriller or some boy's own adventure yarn.

The story gets better, the deeper you dig. The design of this big, extremely conspicuous project was entrusted to one of the borough's youngest architects - the 26-year-old Kate Macintosh. In 2019 we have so-called "starchitects" working for multi-billionaire clients and the richest governments worldwide.  Half a century ago we had incredibly talented, socially-committed, idealistic architects working full-time for local authorities on public sector schemes.

More recently, working all around this area, I was getting almost daily doses of the place. Stopping for a rest in Horniman Museum gardens - at the top of Forest Hill, just to the south - you get an excellent view of the ziggurat-like quality of these flats, as they hang off the side of the steep slope.

Seen closer up, and from below, the buildings lose a bit of that dramatic quality, and after a while they become just another part of the south London landscape, affected like everything else by one's own gloomy moods.

But hearing of a photo exhibition about this development as part of the RIBA's "Six Experiments in Social Housing" season, revived my interest. This was a small, free show of 20 photos of the then recently completed estate taken in 1973 by the photographer Sam Lambert, commissioned by The Architect's Journal for its archive. They have never been shown in public before, and they give a real sense of how thrilling it must have been to be one of the original tenants living in what was a truly modern, even futuristic, housing scheme.

The modest exhibition includes some lovely interior shots, and also some interviews with current residents. One describes how, every New Year's Eve, residents congregate on the "streets in the sky" aerial walkways to enjoy one of the best views of the firework displays in London. A nicely-timed slap in the face for prevailing orthodoxies on social housing design.

What's also great is that this estate is still social housing: it has not gone the way of other modernist icons such as Trellick Tower in North Kensington, where flats are now selling on the private market for millions. Despite efforts by the 20th Century Society and others, the estate has not yet received  the protection of Grade 2 listing - which seems odd. But, by all accounts, it is not in imminent danger of destruction or redevelopment - itself a rarity in these shoddy times.

Back in Brockwell Park, look west, and you see another example of well-designed 1970s social housing - the Cressingham Gardens estate on Tulse Hill Road. This one also tried and failed to get grade 2 listing - but unlike Dawson's Heights, this estate is still having to campaign for its existence. It has been under threat of demolition and redevelopment by the landlords, Lambeth Council, since 2015.
