We did a self build, we had a few problems with planing permission because we are in a conservation area. It took us two years from breaking ground to actually moving in. We moved in 2 weeks before Christmas just gone.
We had two architects in the end the first one charged us 2k and we had no chance of getting the plan through Planning they told us as much at a site meeting. The 2nd charged us £350 and we eventually got it through.
Possibly one of the most stressful things was picking bathroom suites, kitchen, doors etc because we had no idea of how they would look in the room and if they'd fit! It didnt help that we had a 10 month year old. It led to lots of arguments between the wife and me, we're still together expecting our 2nd in January
We picked trades on recommendations from friends, we had 2 major problems the electricians which we binned after first fix, and the joiners who we also got rid of after them taking around 9 weeks to do the roof or maybe it was 13 either way they set us back a lot.
The builder we had was excellent, his brick work was fantastic and he probably sorted out a lot of problems we didnt even know about. He's also my father in law
The downside of having him build it for us was he had his own ideas of how we should have the house - windows, slates etc - which led to a few instances of not talking for weeks after pretty major rows, we obviously got our way in the end and he still hates the windows we picked.
I dont know if we were on budget or over or maybe under, I think it was close in the end, we basically just gave my father in law the money into his account and he spent it on materials, im pretty sure he paid for a few things himself though.
Dont scrimp on things inside your build. Shop around on the internet there are some great deals if you do the research, my wife was brilliant at doing this. Goto show homes for ideas, take pictures.
I think we got things right for the most part.
Were still not finished though, outside needs to be done and the last thing in the house is to get the log burner smoke bombed for leaks. Were getting there
Its well worth it in the end.
