New office buildings

Buildings as in plural, because, dear friends, there are more than one. Let’s start with the announcement in the weekend paper, of a new office block by Studio Pacific, to replace the former ICI house that got demolished after the Kaikoura earthquakes. There is a link to the Stuff article here, but in a truly retarded move, they have cropped the picture so you can’t see the top of it. I mean – who crops a picture online? It’s not like there is a shortage of newsprint in a virtual world! And they’ve chopped off the top, which is a lovely feature. Shame on you DomPost.

The building appears, from this one glimpse, to be quite debonair. Suave, smooth, elegant – spikey too, in the haircut we can’t yet see. In line with my predictions of all future office buildings in Wellington going to be built to a more indestructible standard, it is proposed to be Base Isolated, which makes perfect sense (seeing as the previous building found the site excessively shakey). It has a structural exoskeleton – a diagrid – although unlike the last work from Studio Pacific, where the diagram is hidden below the surface, this one is hidden in plain sight: it proudly wraps the outside of the building. By the looks of the render, it projects out off the building envelope by a couple of feet or more. I’m not sure why they have changed the system from the previous very successful diagrid on the new Deloitte building, but there is one immediate, obvious answer: money.

It’s a lot simpler this way, and the building can stay stiff, while the cladding will be costing just the price of rectangular glazing, rather than the excessive cost of triangular panels. Although not stated anywhere in the article, I’m presuming that the Engineer might well be Dunning Thornton Consultants, as they were the engineer on 20 Customhouse Quay as well, and so they’re the reigning knowledge base on external diagrids in Wellington. The building does, however, have a very different appearance. Here’s the better, full version.

I’m liking the thin black steel beams and columns, with the reflections against the glass showing a deep shadow effect. I think that we can just make out some vertical columns in behind the glass, with a more normal, less frenetic grid than the previous building on Customhouse Quay. It is also proportionally more like the ICI House building here on this site before. Overall, looking good. Is it a bigger building than before? I can only presume so. Are Prime Properties all ready and willing to build it? Again – one can only presume so. Starting in 2019 ? Hell yeah! Let’s do this ! Let’s collectively, slowly, rebuild our city to be highly earthquake resistant.

Coming soon – more new office buildings! – Tennent & Brown – again, a terrible picture in the Dom – do you want to send me through a better picture, ready for the next post ?

I think this might be the render you’re after for the ICI site proposal: http://www.hunterindustrialsupplies.com.au/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/f/o/foamnettingsleeves.jpg

Having quite some experience in this particular field, I can offer the link with some authority.

There’s also a few more renders of the Bowen Street buildings on the Architect’s website: http://tennentbrown.co.nz/news/bowen-campus-design-reveal

From the look at the render (horizontal offset between colonnade bracing at ground floor and exterior bracing above) I would suggest that the exposed exterior “bracing” is non-structural and the main structural bracing is behind the facade similar to the louver system on 20 Customhouse Quay.

Chris – why on earth would anyone add non-structural bracing to a building? Surely no one would fall for thinking that if it “looks” like it has bracing, then it will be stronger? But you’re right – the steel does look suspiciously small and thin and not well connected to the building inside the glass-line.

Still – you’re an engineer I presume – so you’ll know what you’re talking about. But so then you’re not the engineer on this one ?
