Beginning of 2017 started looking at houses.
Looked at 3 properties (60s/70s), calculated, saw that after all the renovations the total sum would be insanely high - decided to build.
Looked at 1 plot of land, the 2nd one was the immediate hit, February 2017.
Reserved in March 2017
Loan approval in June 2017, contract signed
Building application approved in September 2017
November foundation
then came the cold winter
End of March 2018 topping-out ceremony
And then everything was delayed, nothing progressed for ages
June 2018 windows
The rest faster again
Move-in October 2018
So < 2 years from "we want something of our own" to moving into the new build, still possible I think. Even though I had hoped for faster.
