Generally 2 pack is more expensive. I'm not aware of pricing for the polytec venette range. I have polytec white gloss in my kitchen, and looks good. But does show fingerprints in certain light. The polytec venette range is supposed to, not show fingerprints. A 2 pack kitchen would also show fingerprints. I would suggest you get a quote and go from there. But you already have a very good alternative in your tender.

is the room extra hot or cold as well as wet? start with asking the Council about building approval for the original sun room then a building inspection to identify the source of the leaks..there are Building Inspectors (check local services) who can give you a basic condition report for a fee..if the building was never a legal living room and has major problems with the structure it may be better to KDR but if the concrete floor and the roof structure are legal and in good fixable order then you might rethink all the windows, have the roof and guttering checked and repaired, lose some of the windows, reclad outside walls, insulate and line the inside walls to cover over the brick columns and make a more traditional looking lounge but, if you're not happy with the floor height, size shape or location of the room it may be time to consider a whole house rethink....to repair and redecorate the existing room and raise the floor (an extra slab or a timber framed higher floor to match the original house as long as the ceiling height will still be legal) but, without any major structural problems and very good luck with trades and materials) i'd start with at least $30,000 but to replace the whole building around $100,000 probably more but if you plan to spend that amount it might be time to rethink the whole house to make sure that you get the best value from a big renovation... there's a lot of different skills and tradespeople needed so the easiest (not cheapest) would be to employ a builder who takes control of the whole project, organises all the materials and different workers in the correct order and then you pay the builder for their services and they pay for everything but usually better to ask a builder for a fixed price contract so you know what to expect

if pricing is visible and available, there will be a little „pricetag“ symbol on the image, which is clickable. i have come across it mostly in ideabooks so far, but not often

We just had quotes for garage doors and they started at $6,000, then go to $10,000 and the next price point is $15,000. It depends on the type of materials you are using and the door opening. The guy quoting showed us one that was similar to your first photo and had said it was $30,000. All in all, they are not cheap. it was useful to have someone out to quote and help with the options.
