Mmm.
Teaching - if it's at a private school the pay is better, the class sizes smaller and children generally better behaved. I've only one friend in that scenario and she's doing well and enjoying it. I wouldn't pigeon hole all teacher jobs.
However back to the Q - I'm a qualified town planner, I help design and build villages, urban extensions etc. the largest one I was involved in so far was 10,000 homes, secondary schools, parks, shops, services etc.
You learn loads across different disciplines- highways, ecology, topography, hydrology, geology, build phasing, cost control and viability, educational needs, liaise with many statutory bodies including natural England, historic England, highways England, etc etc. sometimes you need to divert utilities, or agree contracts so there's some legal work.
And when it's built you're able to visit and think, I helped make this happen. I absolutely love it. The pay is good, there are loads of disciplines to choose from as above, if you want to specialise rather than project manage as the planner.
Grad salary started around 25-30k, managers 50-70k, directors 100k+. Then you get big bonuses, company car, bupa healthcare, pension, flexible working etc. im a Director 15yrs in, age 39.
