The house now looks like a proper house and has given our enthusiasm and motivation another boost. It actually now looks like something you can live in!
An update on other things; the electricity was connected on Wednesday so we now have live power on site, and we also now have guttering up which looks really nice and blends in well to the roof (hence why you can't really see it in the pictures).
The Eurobrick System is being delivered on Friday and hopefully by then we will have cleared a space to put it in!
