Our Cardboard Box

It's been bit fragmented on site over the past couple of weeks due to Easter and last minute changes to the design. This has had implications for ordering and delivery of materials to site, and the work programme has been a little bit unpredictable. It's edge of the seat stuff here (or is that fly by the seat of your pants?!).

Work continued with the steico all around the rest of the house.  










Then Andrew and Paul started to construct the window supports and sleeves.  Lovely big bits of timber to support our massive windows.





















In a last minute change our sheathing board is now a new product called Timbervent.  This 12mm wood fibre board has been nailed to the outside of the steico beams.  The change is due to the fact that Timbervent is stronger and has much better breathability. It's more expensive than the board previously specified, 11mm OSB3 sheathing, so there has been an uplift in price, but we all think it's worth the improvement it brings.  In general the budget for the build is looking good at the moment.



Timbervent nailed to the ply part of the Steico Beam

Within the fabric of the building there is a gradient of breathability from the inside to the outside layers, this is to prevent condensation accumulating.  We start with concrete block, then insulation (this will be pumped in in a week or two), then the timbervent.  







Our Ibiza-style dance floor roof!

Our house now looks like a giant cardboard box.

The superstructure continues

The steels arrived on site, the blocklayers returned and up we went to the top. 



Huge upstairs window (looking out at the thick fog - a bit of a theme currently)






The kitchen window





The main entrance



Andrew and Paul got going on the steico-joists. 'Steico' is basically two pieces of ply joined by a woodfibre panel which forms a I cross-section.  This is where our MMC (modern method of construction) becomes apparent.  The concrete blocks are the internal layer and will give us huge amounts of thermal mass (this means that the temperatures within the house should stay quite stable). The I-beams provided by the joists are fixed to the outside of the blocks and will support the exterior layers of insulation, membranes and external claddings, so they are doing a lot of structural work.  Andrew talks about how they are basically made from waste material...at least that does something to offset the concrete used.











The roof window spaces are also visible now and I am SO excited about them!  I love that we will able to look up and see the sky. We have one above the cloakroom, one over the larder and one over the upstairs loo.  We've just specified Roofmaker's Fixed flat rooflight, it's going to look spectacular.  They are super-insulated and look gorgeous, I can't wait to see them installed. Roofmaker have a huge facebook following (see here) and really good reviews so I'm confident we've make the right choice.




  



These Dodden boys are fast, when materials are on site they don't mess around, it's a quick build really.  Thank goodness we're moving forward again.  Once you enclose the spaces your eyes are drawn to the walls, and they are pretty perfect.  We've all been commenting on how good the blockwork is.  You could almost leave them bare as an internal finish, but our plaster layer is an airtightness barrier and therefore vital - thank goodness for that (we've been having a lot of 'industrial' design conversations but I think bare block is too much)!



I think it looks pretty cool right now! I like the fins.

If you haven't realised I normally blog about a week behind where we are.  However, at the moment I'm a few weeks behind, so I'm hoping to catch up soon.
