SIP experienced contractor

[Sabine]

Hello,

We've started our self-build journey three years ago. We have successfully obtained planning and are 'just' waiting for the conditions to be discharged and the party wall awards being finalised. We have finance in place and were looking forward to breaking ground very soon. However, the contractor who we had lined up just withdrew himself from the project. We were so happy to have him on board as he not only had worked with our architect before but had also completed multiple SIP buildings before. We're now back to finding someone. We still have @Clays on board for the actual SIP superstructure but need someone who can clad the building in brick and put the roof on, essentially getting it water tight. We have quite a few brick details such as quoins and therefore need to get this right to bring the design to life. Do you have any advice where to find a SIP experienced contractor?

In addition we need someone who can sort the groundworks including piling for the basement. The basement itself would be supplied and installed by a company called Glatthaar, who would leave us with the basement and foundations in place.

Do you have any advice where to find suitable contractors? We have exhausted the links the architect has and can't find any details for experienced SIP contractors online. Any advice would be greatly appreciated. It feels that this is the last roadblock we need to overcome to finally create our family home. Thank you! Sabine

Welcome

 

Is there a reason that you have chosen Structural Insulated Panels and not other methods of construction?

I can see the logic of choosing it along with a contractor experienced in it.

But otherwise I'd use whatever is normal locally 

 

The basement is not building but Civil Engineering so both SE and contractor need to be expert.

By piling I assume you mean sheet piling to retain the earth while digging and building. What structure are you allowing for the basement?

Have you considered ICF, if you have a basement?

Sounds like a top spec build. Good luck with it. 

 

I think someone here built an MBC twinwall over a basement. The name escapes me. 

 

It may be an option for you.
