Original Question:

I am looking for a recommendation for Plinth, base and Vitrine construction in London. Can anyone please suggest good companies to use?

Here's a couple of places White Wall - http://thewhitewall.co.uk/display-items/ Big Soda - http://www.bigsoda.co.uk/plinth-fabrication/ Darbyshire - http://www.darbyshire.uk.com/artist-services/ Fish Fabrications - mainly work in metal http://fishfabrications.co.uk/ Acrylic Design - http://www.acrylicdesign.co.uk/#&panel1-1 Scotland - https://make.works/blog/ten-fabricators-in-scotland However there are quite a few freelance techs that make plinths for some extra cash - if you have specific needs let me know and I can put an advert on the main site for you if you like?
