Yes! Stretch ceiling will sit perfectly flat, and it never sags, bubbles, peels, flakes, moulds, or fades! It can be installed right over the sagging ceiling, or, if it is in danger of falling, you might choose to knock the existing ceiling out and then install stretch ceiling right over the empty space. You may also want to check to make sure that the floor above isn't sagging, in which case you may need to install a structural column or beam. We carry over 280 colours in high gloss, satin, matte, sandy matte, and canvas textured finishes, as well as translucent, iridescent sparkle, and we have the ability to digitally print any high resolution image on any of the above.

You asked about this specific ceiling. Combined with all that's going on in that room, that ceiling goes too far for me and that's saying a lot. I do love the look of a decorated ceiling and this one could have been spectacular without all of the action going on under it.

For a "couple of days a year" get a pedestal fan straight on everyone and leave the features in the ceiling. Seriously...I have 12 ceiling fans in my house and two wall mounted fans...the wall mounted fans are so much more effective then ceiling (and I don't know where you live, but did you know fans have a "summer" and "winter" setting??). Most people don't. Tip: turn the fan off before changing the setting.

Is there a particular reason you want to lower the alfresco height ? If I had to make a choice , I'd almost prefer to go for 2.7 indoors , 3 metre alfresco , because thats where you want that open feeling , the luxury of space and height , moreso in in an alfresco . As far as being noticed , the only time it wouldn't be too noticable ( IMO ) is if the alfresco floor was lower than the house level -- if you step 'outside' through a standard or sliding door , and the roof feels lower , I suspect you would notice it . That , afterall , is why you go for a 3 metre inside height , to feel open and spacious .
