Well, following suggestions from both my wife and son, I've started to include pictures of the inside of the building to show progress.
Immediately to the left in the picture are MDF sheets leaning against the wall. These are 8' x 4' and will be used for the narrow side tables that will be 24' long and about 2' wide. The white sheets further down against the wall are melamine coated 10' x 4' MDF sheets. These will be used as shelving under the main tables. They are ready to go and require no additional work except to cut and then pin/glue edge tapes to finish the job.
In the centre of the piccy are more MDF sheets. The top 2 are melamine coated but underneath are the main MDF sheets for the centre tables which will be 24' x 6'. They are 25mm and weigh a ton, took 5 guys to get them in! You can also see the lighting, just. There are a total of 8 x 5' twin natural light fittings with reflectors. They are positioned to be over the centre of the main centre tables so that there is no shadowing.
The whole room is painted brilliant white and is insulated. The concrete floor will the last job finished. I will leave it until Easter before finally completely painting it and carpeting it.
And lastly, but not least and what this is all for, the first troops are based. Apart from awaiting their eagles, you are looking at 2 regts of infantry, 6 btns, the 3rd Ligne in the foreground and the 18th Ligne in the background. Each base has a computer generated identification label as does their position in the storage tray. There are 684 figures in the piccy, 114 per btn (nearly squeezed them all into the frame!). This time next year I hope to have nearer 160 btns!
