My New Year project is also going to be installing CCTV. Below is a very crude drawing of the layout (not to scale) and I think with 4 cameras I can cover almost everywhere. The yellow bit is the only blindspot but it's also where a car gets parked. The house isn't really accessible from the back or the sides without going through neighbouring gardens first so blindspots there are less of an issue.

I'm planning to order one camera first just to check focal lengths in each position but I think I'll be looking at potentially 2 x 2.8mm and 2 x 4mm. Currently looking at turret cameras and either a Hikvision setup (eg DS-2CD2347G2-LU) or Dahua TiOCs such as DH-IPC-HDW3549H-AS-PV with the same brand NVRs unless there are any better recommendations? The rest of the home network is Ubiquiti.
Are there any better locations to cover the blindspot or is it likely I would need a 5th camera. The two cameras down the side of the house cover sheds and doors.
Thanks for your help.
