Hi All, After a little advice/ thoughts on my pads/ beam and and joists dims for a smallish garden room/ deck i'm building. Its on a fairly substantial level change - approx 1m. See attached sketches that hopefully explains well enough, perhaps i'm over engineering here, but perhaps not! - Basic premise is footprint of approx 5000mm x 2500mm. 2 rows of 4 pads to make 4 short beams running front to back. Posts to be tripple 2x6s ( too much!?) to double 2x6's for beams with 2x6s joists on hangers. Beam spans will be approx 2000mm between posts, and joists span 1700mm. - some simple cross bracing to posts - Single story timber frame building with cedar shingles 3m width and then 2m width decking. - Concrete pads approx 400x400 x tbc depth with post shoes cast in to hold above ground level - Ground is soft topsoil but down to much harder sand/ clay. Any thoughts/advice appreciated.

Oh, our house is approx 220m2 and 5 bedrooms, 3 bathrooms as well.

Hi all, So we have a 16thC farmhouse, we renovated it 5 years ago, new windows, extern insulation etc but obviously still not hugely air tight. We just replace our old old Duplexvent with a new Vent Axia Advance as old one died and callout are half the amount of a new unit! So, we've never balanced the system properly just used it to control condensation and fresh air. So obviously it won't be working quite right. I had a few questions anyway on its operation and peoples thoughts. 1- design was by BPC and we have more of a positive pressure system, 3 supplies in hallways ( that are high flow) and normal extracts. So our 209m3/h translates to approx 60l/s flow rates (screenshot of flow rates from bpc desogn) This technically should be what we have set on the unit correct? This turns into quite aloud gale at supplies and really we still get a large air flow at vents at half that.... Question is is it really bad to run the supply at say 30l/s but keep extracts high to control condensation in.our bathrooms? Does the system just not work that way and just ramping up extract wont work or will mess up air temps. 2 - on the app, is the internal temp the temperature inside the mvhr unit? Its in the attic. The 1st day i turned the system on the supply temp was more like 17 degrees and now far lower around 13? It's really cold outside so do people think its because its so cold outside and in the attic that my supply has dropped so much or is because I'm faffing around with the fans and unbalanced the system so much? I assume with such a low internal unit temp the heat exchanger can only do so much in say sub 5 degrees external temp? I know I need to balance the system properly but any thoughts on the above greatly appreciated. Thanks.
