We had to strip out the whole building then start all over again.
All the services had to be changed and altered; also, things were brought up to building standards.
The colours of the building are earthen colours which should not date. The building was renovated and built for easy maintenance and also for fire resistance. The building is quite deceptive. On the outside it looks plain but on the inside it has all the modern creature comforts. Below are the photos of the outside after completion.
The concrete subsurface was cleaned and separated by a moisture barrier provided by the supplier. This must be installed to minimise moisture from expanding the floor boards. I would strongly recommend that you read all the installation procedures and follow them if you are doing it yourself.
