I think white against the dark grey has the biggest visual impact but with dark grey windows. If you wanted something different you could always try a different colour over the door area or even the oak. I can't unfortunately find any images..

As a showroom I presume you have a big window behind the hoarding. Since there will be little wall to clad I say don't bother- keep the look unified with the same top and bottom- the trick is getting noticed from the road- consider either a bolder colour for the render- perhaps a blue/black. Or perhaps an awning? Or perhaps you put a window display in an eye catching colour? Or perhaps you made the frontage look more luxurious with topiary and a red carpet? Best of luck whatever you decide

Hi Johnleh, just to try and explain a couple of points re;- protection of mild steel. Basically, Galvanising is dipping the components into a vat/ bath of hot molten zinc,( hence the hot dipped galvanised term. ) This coats the metalwork with a shiny/ mottled silvery finish, because this is zinc it will not corrode/ rust as unprotected mild steel would. This process is used quite commonly to give mild steel a longevity of life with a very minimal amount of maintainence. It can also be powder coated or painted on top to give another colour finish if desired. Galvanising is usally recommended in higher corrosive enviroments, such as coastal areas. If the metalwork is inland and in a less corrosive enviroment, powder coating ( this is where the metalwork is sprayed with a powder and statically sticks to the work prior to being "baked" in an oven. ) or traditional prime and paint can be used. Painted metalwork however would normally require more regular maintainence and can become awkward in the hard to get places. I hope this makes sense and sorry I did try to keep it brief !!!.........Regards, Leigh.

Well our builder/joiner used to be a kitchen fitter so he was going to be fitting it but he’s just gone awol and run off somewhere (left all his tools and taken out money and not paid half of his contractors!!) So we have had to take over the project mid way :0( He hasn’t planned the extractor in otherwise he would have designed and made the roof section the pipes need to go into, differently. So as we don’t have anyone yet who can take over the whole thing - we are trying to work out the niggles as best we can and make life easy for ourselves. The plasterers are hopjng to board in 1-2 weeks so I’m thinking the easiest thing to do is to have exposed pipes which will work with our industrial theme I guess. That way it won’t effect the ceiling as it will just under it.
