Week 5 – Finished slab

Thanks to the help of Concrete Floors (and suppliers such as Firth with green certified concrete) the slab has been finished. The formwork was pulled off today, revealing the nib around the perimeter of the building (except the garage).

Tony Doherty, Detailer and Production Manager from Smiths ITM East Tamaki has been detailing the frames furiously for the last week, and completing a full 3D model of the timber work. He produced over 100 pages of details for the skeleton of the building. Following a review by the wider team yesterday (including S3 Architects, Palladium Homes, Green Being, and with help from ProClima) the frames are now in production at ITM and should be ready for delivery midday Tuesday. Special thanks to Paula Hugens from Green Being and Matt from S3.

Palladium are in the process of booking a crane, to assist in standing them up. The frames are over-length (designed to avoid thermal bridging) and will require special transport and a little help to erect. Careful planning is required to get the sequence right to stand these up. Palladium are going to work from the back (lower) end of the house, and insert some of the internal walls as they go, and work towards the front (higher) end.

ProClima will be on site to assist in securing the Intello vapour check/air tightness membrane at critical points which won’t be able to be accessed later (i.e. where internal walls will push into external walls, and around the midfloor plate).

By the end of Wednesday next week the site will be transformed and we’ll get a first look at the structure that will become our home, and hopefully an example to many others.

We’re a bit over budget, but still targeting a build around the $2500 per m2 which will be exceptional given the expected performance of the project (not taking into account any supported products). We will be adding full budgets to the blog soon, as one of the burning questions in the industry is just how much should/could it cost to build a home far exceeding New Zealand building standards, and just above standard levels in Germany. A home that will receive a credit from the power company each month, and could probably power the street’s christmas lights and still be positively producing. A home that won’t fall below 20 degrees Celcius all year, including on the coldest winter night (with no heating), one that will be deathly quiet from the outside world, and that will have exceptional air quality properties. More soon!
