Hi, we do architecture too, although not as intensely as you clearly do. Firstly some observations. I think your layer height of .200 is a good compromise, that is what we use for architecture normally.
For your current settings I think you are too hot. With .4 nozzle .200 layers and 20mm/s we would be below 200; of course filament and your printer will affect this but likely to be within 5 degrees. Going cooler will probably improve your quality that you experienced with the previous models.
0.8mm for top layers is too marginal for 15% infill. Take it to at least 1.2mm. If we use infill it is normally 40% or greater and we use 1.0mm minimum for top layers. 15% infill needs more unless it is a very small model. This building was printed with .200 layers at 30mm/s and temp of 200. Size is 257mm x 145mm x58mm with a total print time of around 35 hours if I remember correctly.
Things to try.
1. Do you actually need infill? – you seem not to have open windows so people cannot see inside. If you have a flat roof then either print it separately or print as many top layers as you need to get a decent finish. We never print infill in our buildings.
2. White is the worst colour; if it is possible use a different colour which will give you a better finish and so perhaps let your print faster (yes I know white is popular in modern architecture!)
3. Are you using Cura 2.n or 3.n? They have an increasing number of tuning options. Go for a faster speed and try some of them to see if you can recapture the quality.
4. Set all your print speeds the same, except 1st layer and travel.
And do not forget that with all other things being equal, speed is the enemy of quality .

Hello Sander, thanks!
i would like that, 99% of my work consist of architectural buildings. I can definitely post some more pictures.
The prints u see in the picture were printed at 30 or 40 mm/s i think. But when i use that speed on these files they either start to under extrude or not connect properly.
Thanks:) took me some time.
What thickness would you recommend for my walls and infill %?
here are the pics of the 'failed' prints. They printed completely fine and look neat, besides the triangles showing through the top layer ( eventhough the thickness of the top/bottom layer is 1.2 mm which equals 5 layers.
