I did take a compass with me, I wanted west/east orientation and I now have the best of orientations ie s /sw at the back, which means sun on the back wall first, then on the front but the garden is sunny almost the whole day
I used to live in an eco house with very large windows on the s side but with solar shading ie balconies and overhangs. That was a very good situation, the north windows were normal size. No way did I ever want a s facing house, not without solar shading. My neighbours at an angle to me get the sun from the s all day in the front, very hot in summer and their back is shady.
Location is so important, besides the facilities needed as we age, personally I am detached and have gorgeous old long gardens to 2 sides, garage s facing and my house on the last side. Not overlooked by anyone
Another two I turned down had air source heat pumps, noisy ugly things, especially the one below the main bedroom window
