Roof is progressing well

The main roof structure is now in place apart from some steels which will be installed over the coming week. We can now start to weather proof the building in order to start work inside. The main students used in the construction of the roof is a third year group tutored by steve who have produced some very good work to add to their college assessments. As the building takes shape and we can now start fitting it out, pressure for the building to be completed also starts to build. Timing is critical especially for the rendering of the straw as rendering too early before compression is complete will result in the bond being broken between the render and the straw. Rendering too late and we will not have time for the lime to cure and the students to carry out the work as they start to complete their work at college and leave for their summer break. I am sure anybody visiting the site will agree the building is starting to look impressive in its surroundings at occombe farm.

Roof work begins

It is now time to start to push on with the roof work but recent weather has slowed up progress. although the storms have not affected the building structurally I am unable to work on the roof if there is a threat of rain as the bales are still vulnerable and require constant protection. This coupled with a sequencing issue regarding the installation of structural steel works before we can complete the structure is giving me a headache. The students are still gaining valuable experiance with a whole group of third year students constructing the main roof structure with assistance from their tutor Steve.

Walls are completed and compression begins

After a significant push by students and all involved in the project, plus a kind spell of good weather we have managed to bring the project back on programme. That being with the walls completed and under compression for the half term break. We even had students assisting the farmer to restring some bales on his farm as a significant number of the original bales were deemed unsuitable due to them getting wet. Again student accuracy amazed me again with the top ring beam being exactly square and exactly plumb over the bottom beam on all four sides. This is with a level of tolerance within 5 mm. Considering we have been using a building product as natural in size and shape as a straw bale. these pictures show the top beam in place and being staked down to the bales below. The next stage is to allign all of the bales with the beams and compree the straw over a period of a week or two. This will then be ready to install the roof.

The walls are growing...

Good progress is being made inbetween the showers. A few bales have got wet and have had to be discarded and some replacements will be made up as quickly as possible. Nick and the students aim to get the upper ring beam in place and ratcheted down before the half term break - which starts in five days time...

Earlier this week Occombe hosted a visit by 20 farm shop operators from across the country who were attending a workshop organised by FARMA (the Farm Retail and Markets Association). The workshop was for people to find out how Occombe Farm won Best Newcomer of the Year 2008 in the annual FARMA Awards. There was great interest in the straw bale building and Nick gave a tour for the group. One delegate has gone away vowing to build the first straw bale farm shop in the country!

Wind and rain try to disrupt progress

The dark picture is due to the weather not the time of day, it shows the difficulty we face with covering over all of the straw each day with tarpaulins and braces to prevent the straw walls collapsing or getting wet.

Straw walls are on the up

Here are some images of the straw walls being constructed on site. It shows each stage from the first bale being positioned to the hazel stakes being driven in. Progress on site has been rapid with the spell of good weather helping us (for the moment). We currently have five courses of bales in place with two to go, this will happen when the scaffolding has been erected.

Ring beam is almost in despite the weather

Work is almost complete on the first ring beam so that the straw can be installed. Here you can see that we are using ratchet straps to bring the beam into square. We checked the diagonal measurements which are within 10mm of each other so already a very good level of accuracy is being achieved by the college students. All carpentry students so far have been 16 or 17 years old so this does bode well for a quality workforce for the future.

We had great difficulty lifting the sections of beam over the tie down bolts but with a bit of persistance and and a few well directed hammer blows all is in place and located in the correct position over the tyres.
