End of week 4 progress. Most of the block work done now. Ceiling joists in. Next week they are starting on the roof. 

Bit of bad news today that we're going to be without the boiler for about 6 weeks at the end of Jan. Difficult timing but as we have to move the boiler then wait for the floor to be done in the extension before the new one can be installed, it's just how it is. It will be worth it (on repeat in my head!) I kind of hate everything about this house at the moment!!
