That is a loaded question. It is kinda like asking how long it should take to catch a ton of fish.... How big, how tall, with what and where and when. Vinyl siding is a lot faster than steel a shack is faster than a taja mahal and it goes a lot faster at 70 degrees than 20 below. in other words how much wood would a wood chuck chuck if a wood chuck would chuck wood..
Varies greatly depending on size, location, cost, amount of workers, level of finish etc. etc. However, you should allow 6-9 months generally with a contractor and 9-12 months for a self build from my experience.
In Canada the avervage home should only take 5 months max. First month for permits and the next 3 to 4 months to build.

If you a trying to get to the Volcano Overlook, and are stuck at the Geyser Plains, I recommend you don't build a mansion bungalow. Instead, build a one room hut until you find the chisel...
SPOILER:
There is a narrow path, leading up to where you will find a large rock (boulder). Round or walk around that area. Then, press circle (on a console) and check Tools. Look at the last tool. There should be a chisel. It cannot be used. Go to the boulder and inspect. Your Sim will get their chisel and push the boulder. It will fall on the geyser and you can pass!
Sunrooms can be stick built or pre-fab. If you choose to build your own allow enough time unforeseen problems, such as the weather. The size of your sunroom will determine how long it takes to build, typically 1 to 3 weeks. A pre-fab sunroom can be installed in as little as 1 day.
