If you want it to recede into the surroundings use a dark colour such as Woodland or Monument. Use it on walls and roof. Using it vertically and horizontally would add a nice feature to it when up closer. The hardwood for trims, architraves, etc. would look fantastic, in particular if they were kept oiled rather than left to go grey.... A light colour would mean the dwelling could be cooler in summer perhaps but shading from tree's may work just as well. If a light colour was used it would stand out from kilometres away.... not ideal at all.

Thank you for your comments - I did a bit of a mock up with various colours and am erring towards a darker colour as it would blend in more. When I zoomed in on the photo I noticed the house down the front of the view has a monument colour roof so that gave me a bit of insight into how a dark colour would sit amongst the trees - if I wanted to tint it a bit more towards the water colour (although this changes on a daily basis!) I could use ironstone which is like monument with a touch of blue. The heat adsorption by the darker colour doesn't worry me as much as our roofer says it doesn't make that much difference as we will have insulation - it outweighs the reflection issue that a light colour would have. As far as making it a trafficable space - there is no shortage of viewing platforms in the rest of the house - I did do the sums on a rooftop garden and am tempted but at this point it would add about 8k for extra support, 8k for waterproofing and then about 20k for all the rest - although I suspect I could do this last part cheaper than that quote. The block is not short on garden space!

i would email the boss to say that you are "happy to pay the bill minus the amount for the product not used plus enough to cover the extra product used" (include the individual amounts, if known) and quote the final amount that you expect to pay for the job "as soon as the scratches are repaired" best of luck and hope you're happy with the final results

When selecting windows it’s a good idea to think about how they perform thermally. The frames influence this as well as the glazing. Timber, uPVC and thermally broken aluminium frames are lower conductors of heat and cool than regular aluminium or steel frames, but they do come at a cost premium. Timber frames also require much more maintenance. And, of course, aesthetics come into play. The windows you select will affect your NATHERS or BASIX rating and will also affect your heating and cooling requirements.
