basic render of a system with three balloons and four anchors (three round the edge and one in the centre):


note that this is only a first draft. in particular, the structure would not curve back outwards (the form finding parameters were not set up properly), the top nodes would be less spikey and the general profile would be lower

this is bit late to the party perhaps, but I've been thinking again about canopies and inspired by the helium plastic bags I think I may have found an option that: self-assembles, is cheap, easy to design, and is interesting/fun. see what you think.

I was wondering, for no particular reason, whether, if you attached a helium canister to an infinitely stretchable balloon*, it would float off:




but from here I started thinking about blimps and the hindenberg and realised that if one was to through a sheet over this guy:




you might get a scaled version of this (these aren't very good images but I think you get the idea):





what's nice is that, to build this big tent all you need to do is drape some canvas over a deflated weather balloon, tie the balloon/canvas down to three or more anchors (some bricks, a box of mud, etc.) and then turn on the gas. this means that, as well as being fun and easy to do, it might be suitable for temporary shelters for disaster relief (I think one of the other groups was loking at this at some point) as all you would need to deliver to the site would be the canisters or even just fly a blimp there and pop a cover on. clearly wind loading could be an issue, but then the structure could just be lowered in bad weather.


in the course of writing this I have unfortunately discovered that this idea is not 100% new:

but then nothing is, and there's still plenty of scope to play with the idea. for instance, by placing the balloons on the inside and by stretching and folding the canvas you could achieve much greater lateral rigidity while achieving almost any shape/form you wanted. in way, this would be almost the exact inverse of what heinz isler did with concrete:

as I say, this may be a bit late in the day but I thought I'd put it out there anyway.

*I was actually envisaging sticking a canister in one of these and then letting it float off like a chinese lantern. unfortunately it doesn't work (safety aside)
status update



Mike and I met the Headmistress of All Souls Primary yesterday and it's good news. not only is she really keen that we use their roof to do a joint project for LFA, but she also really liked the ideas that we already had:


she loved the idea of a rooftop allotment as not only does the school not have any green space, but nor do most of the kids as they all live in flats locally (something that I hadn't considered up till now).


she was also very keen on the idea of providing some sort of canopy/enclosure over the roof so that they can use this space in bad weather - it is essentially the only play area that the school has and so when it rains the kids have nowhere to let off steam and it is a 'nightmare'.


the only caveat she had was that the roof must still be usable as play-space for the kids (e.g. to have small games of football, netball etc) but this is what we have envisaged from the start and just serves to reiterate that it is our intention to find supplementary not alternative uses for the roof - hence our focus on retractable structures.


finally, she suggested that it might be possible to organise a design workshop with the teachers and the older pupils to get a better idea of how the space might work etc


so, all good

Core idea

From the very beginning of the project we have been very keen to collaborate with All Souls to try to find a way for them to fully exploit this rooftop space. We have taken care that whatever we consider does not conflict with its role as a playground/sports pitch – we are looking for supplementary, not alternative, uses for this space.

Bearing this in mind, the core of our proposal is to create a rooftop allotment that can be easily retracted to the perimeter of the site, leaving the playing area free. We intend to use the pre-existing ‘cage’ as a trellis to grow runner beans, vines, tomatoes etc. on, before building retractable allotment boxes, similar to chests of drawers, in which they can grow ‘low rise’ vegetables and herbs. We envisage a scenario in which each class is given a plot to tend, perhaps growing the vegetables for school dinners. In the long term, we intend to build a wormery to produce compost from the school’s own food waste.  

We believe that there is a great deal of scope for this to become a model for other inner city schools to follow, providing a fun way for young urban children to learn more about nature and the environment, what constitutes a healthy diet and the importance of food waste, while also significantly increasing the local biodiversity.

For the duration of the Festival, we plan to celebrate these ideals by transforming the rooftop into a fruit and veg jungle that the children can explore and get lost in.
state of play


michael's sent another email to the head, suggesting that a few of us drop round to the school to show them what we've come up with so far, so this would seem to be a good moment to take stock of where we are.

complementary use of space:

our central idea is to find a way for the school to fully exploit their rooftop without depriving the children of their playground. therefore we are looking at structures/street furniture that are retractable or which leave the majority of the space free for the children to play in.


green space:

this area of london is horribly short of green space, leading to the idea of some form of roof garden. however, this might seem to get in the way of the kids using the roof to play football/kiss-chase, so we get to the idea of a retractable rooftop allotment (a hanging garden might also be feasible, but raises lots of issues about how it would be tended, what clearance would be necessary, planning issues, etc.).


retractable allotment:

our core idea. this ties together elements of vertical city farms, hydroponics (possibly), complementary usage, urban greenery, retractable structure (c.f. retractable seating but with fewer, deeper layers), as well as being a great learning resource for the school: e.g. each class has its own plot which they have to tend, teaching them about biology, the environment, diet, etc. in short, it's got everything. we need to do a bit of research into what plants/vegetables you can grow with very little head room - lettuce, carrots and cabbage being obvious examples.


enclosure:

supplementary to the rooftop allotment, it would be nice if we could make some form of enclosure for the roof, whether temporary or retractable, to clearly define it as a new space, rather than just an object in the same space. this would provide further benefit in terms of maximising this resource (the rooftop) by allowing it to be used in all weathers. for more details on this, see earlier blog titled 'enclosure'


feel free to add to this if I've missed anything
street party




pending further contact from the school, I think we need to be prepared for the possibility that we only have the space for the weekend, not all week. in this case it might be worth thinking about organising some kind of event to go alongside/celebrate our project (rooftop allotment).


taking my cue from the location and the fact that this is jubilee year I'm thinking of a street-in-the-sky party. it is also the 40th anniversary of the completion of the (soon to be demolished) robin hood gardens estate in poplar, designed by the smithsons - the originators of the whole streets-in the-sky concept:








combining the idea of a rooftop allotment with the smithsons' streets-in-the-sky would seem to lead directly to this, the new york high line - another project all about finding new uses for dead inner-city spaces while also inserting much needed greenery into the urban fabric:



(see also le coulee vert/promenade plantee)


finally, if we did choose to go down this route, and particularly if the school is against the idea of building a permanent structure on the roof, then we might be able to use the bunting+balloons+streamers+etc to delineate a kind of temporary enclosure and create a self-contained space of the roof:



as you can see, I'm thinking of something nice and kitch, all 1970's and vicky sponge

Dear Sir/Madam,

My name is Michael Emmerson, and I am writing to you on behalf of 4 design engineers working nearby at Ramboll UK to bring to your attention an upcoming event called the London Festival of Architecture. I spoke to a colleague earlier who suggested this email as the best way to get in touch, and hope that you have 5 minutes to consider this proposal.

The London Festival of Architecture is a bi-annual event taking place across London but with a focus on the local area, and celebrates intelligent architecture in the community around the city. This year the main design focus is recycling and reuse, the expression of which is to fit around the theme of “The Playful City” in reference to the upcoming London Olympics. This is a great opportunity to educate about a serious problem in a fun and active way, and we would love the chance to get involved in collaboration with a local organisation such as your school.

The All Souls Primary is perfectly placed to help make an impact by providing access to the attentions of the next generation of Londoners, both within your school and amongst visitors. What we would love to achieve is a collaborative effort combining our engineering ideas and skills with input from your students to produce a series of interactive exhibits that the students and general public alike will enjoy whilst highlighting the underlying issues. This promises to be a great event, and one that should reach a wide range of people to enhance awareness of sustainability in a fun and engaging way, especially in your own students if involved in the preparation.

The event is held between the 23rd of June and the 8th of July, and in an ideal world we would love to present for a whole weekend, although fitting in around the school’s commitments is a priority. Is this something that you might be interested in? If you have any questions don’t hesitate to give me, or James Clay, Niall Flynn, Edward Boase, Robert Ferris, a call on the numbers below or alternatively get in touch via email and we will be happy to share with you some ideas we already have for this project.

I look forward to hearing from you.

Kind regards

Roof Garden - Drainage Design Options


History of LFA
2004-The London Festival of Architecture started out in 2004 as the London Architecture Biennale-Clerkenwell area. 15000 people turned out for the opening event -St John Street when a herd of long horn cows were driven down to Smithfield market to recreate the movement of livestock that occurred there until the 17th century
2006-Events were held along a route linking Borough, south of the River Thames, with Kings Cross in the north. The theme-highlighted the impact of the construction of the new bridge on the economy and the planning of the area around Bankside and St Paul’s cathedral. This included a range of exhibitions, open studios, walks, tours and bicycle rides.
2008-Actvities across five key areas or ‘Hubs’, with largescale public events taking place in a different Hub each weekend. Each of the Hubs covered an area with a very different character - historic, present and future – and full of different institutions and activities. Typical past activities include exhibitions, lectures, walks, talks, bike rides, installations, temporary structures and tours of historic buildings. Events range from exhibitions of work by architects from around the world, to local visits to buildings of architectural interest.
2010-The Architecture Foundation was proud to deliver the London Festival of Architecture 2010 in partnership with RIBA London and New London Architecture. The Festival, running from 19 June to 4 July, was a city-wide celebration of architecture in the capital. As London gears up for the London 2012 Olympic and Paralympic Games the Festival looked at ways that planners, architects, clients and local communities play their part in the development of 'The Welcoming City'. LFA2010 had three weekends over which visitors were encouraged to explore three key areas of London, namely; the Nash Ramblas, Bankside Urban Forest and High Street 2012.

LFA 2012

Curated by RIBA London, the Architecture Foundation, New London Architecture and the British Council, LFA2012 will take place over three weekends across three London hubs:
  • City and Southwark (23rd /24th June)
  • Fitzrovia and Bloomsbury (30th June /1st July)
  • Kings Cross and Hoxton and Royal Docks (7th/8th July)
The theme for LFA 2012 will be ‘The Playful City’, proposing ways in which both Londoners and visitors can be active participants in the city. From reinterpreting familiar places through new installations and animations, redesigning public spaces to encourage physical fitness in the spirit of the Olympic Games, to testing interactive forms of consultation and planning for future urban development, festival participants will be encouraged to play in, and play with, the city around them.
Oikos is ancient Greek for house and the root word of economy and ecology. Embracing these principles, An exciting theatre project was embarked upon, combining a unique mix of public-made art, architecture and performance that explored how a new sustainable society could flourish in a world altered by climate change.
A Southwark playground was built in the heart of London, where award-winning Berlin-based architects Köbberling and Kaltwasser worked alongside volunteers to create The Jellyfish Theatre, the UK’s first fully-functioning theatre made entirely from recycled and reclaimed materials (see below).
Focussing on energy-efficiency, co-operation and human-scale construction, The Jellyfish was open to the public as an exhibition space.
With climate change already impacting on our lives, The Red Room commissioned leading playwrights, Kay Adshead and Simon Wu, to examine ways our society may adapt for survival in two urgent and inspiring plays written specially to be performed in this unique venue.
Materials for this project were provided by Diamond Waste – and the option of using them is open to us.
The following is a list of materials actually used in 2010: Timber, windows, doors, nails, screws, bolts, recycled chairs, benches, stand seats from football stadia, roof material, tarpaulin, metal beams and skips.

enclosure




I've been thinking about what our options are if the school likes the idea of enclosing the roof in some sort of enclosure




i) permanent or retractable? for now I think we should assume the latter as not only is this more onerous for us but is much more likely to get the ok from the school. also, the idea of a retractable enclosure fits much better with our aim of finding supplementary, not alternative, uses for the roof (we don't want to replace one space with another, but to add to it).




ii) how retractable? should the whole structure be movable (difficult) or should we looking at having a permanent skeleton with a retractable cover (see frank's cafe in previous blog)? again, I think the latter (primarily for reasons of feasibility and likelihood of approval, but also because I like the idea of the skeleton defining/delineating the volume even when the roof is fully uncovered.




iii) materials. wood would be a good place to start w.r.t. the skeleton for obvious reasons (sustainability, the idea of a roof garden/allotment, public acceptability, etc.) but this doesn't mean that we should be blind to other options, particularly if we could source some good stuff from the recycling people Niall spoke to... for the fabric, I would be very interested in using scaffold wrap (the white plasticy stuff they put around building sites, see berner's street hotel)




there's a building on trafalgar square that's currently being refurbished with the top two storeys clad in this material and it gives the building a kind of milky, ethereal appearance and feeling of weightlessness (esp. at night when it's lit up from inside and glows softly). actually, it's not unlike the new effect that SANAA did in new york (below) or that OMA were going for with the Rothschild's building. people generally consider building sites to be eyesores, but to my mind they often provide a lot of interest and dynamism to the urban environment (certainly skyscrapers often look better before the glass is added) and it'd be great if we could convey this.







iv) form. difficult to talk about this without the aid of sketches but I don't have a scanner at home so will just have to add these later. am currently in two minds on this one:


a. curved edgeless bubble (perhaps even a blown up polytunnel considering our aim of creating a rooftop allotment - this links in quite well with the idea of using scaffold wrap), making a clear contrast to the building below while at the same time being quite soft and unobtrusive. the trouble with this option is that it wouldn't really work in this way when the canopy is retracted - it is essentially dependent of the fabric. shigeru ban is a good point of reference for this kind of thing ( = joseph paxton + polytunnel):





b. to go for a sharp rectilinear skeleton, keeping the structure and the canopy/wrap very distinct.


as I said, this doesn't really work without sketches, so I'll have to come back to this. I suggest that this is something that we should all look at together
have a drink, watch the movie and then take the plunge



here are a few projects that have a bearing on what we intend to do. the common theme is the reusing of space, getting the most out of previously dead spaces. (I mentioned them in our meeting the other day, but here's a bit more info)

1) frank's cafe - practice architecture and price&myers



A cafe/campari bar on the top deck of a multilevel car park in peckham - amazing views, overpriced drinks. good architecture though. what's interesting from our point of view is the rooftop location, the retractable canopy and the use of old scaffold planks as primary structural members (something these architects have used elsewhere).


2) cineroleum - people loosely connected to practice architecture (inc. myself in a very minor role)


They converted a disused petrol station in farringdon into a 'pop-up' cinema for a few weeks. again, they transformed a dead site into something much more valuable with minimum outlay. also, they cut up the old scaffold planks to make the cinema seats. the project was so successful that there was strong pressure to keep it running beyond the original timeframe but the architect insisted that it was 'pop-up' not permanent.



3) southwark lido - LFA 2008




temporary transformation of a fallow site next to the railway line in southwark (normally used for car parking and storage, I think).

please read this, it gives a good overview of what's involved in a project like this, as well as what it's really about - these are the kind of things that we should be thinking about
