In my case because it was - own office in a building 15 minute walk from where I live as the only developer working on an interesting problem Vs a 7 mile commute by public transport to work on a less interesting problem in an open office with 30 other Devs. It just wasn't even a choice for me, the final kicker is employer operates a strict 9-5 policy for work, not had that expectation on a Dev job in a long time.
