About Us
Green City Homes is a residential property developer and principal contractor based in the South of England, delivering small-to-medium new-build housing schemes. We work remotely as a team — our directors are split between London and Portsmouth — and manage projects hands-on across the full lifecycle: land acquisition, finance, planning, construction, and sales.
We are currently building an 8-house development at London Road, Holybourne, Alton (GU34 4EG), running over the next year, and expect to take on a second live build during that time — so this role can grow alongside a genuinely active site pipeline, not a single project.
Job Summary
We're looking for a proactive, highly organised Bookkeeper/Administrator to manage our financial records and support the wider business as we grow. You'll be on site in Alton every Monday and Friday (Wednesday too, ideally). This isn't a back-office-only role — you'll be visible on site, working with our site manager and build teams, and will have real scope to shape how we run our finance and admin processes as the business scales. You'll report directly to the company directors.

- Work with our external accountants during reviews, audits, and year-end
- Help identify and implement improvements to our financial and administrative processes as we grow

- Experience setting up payroll, in addition to processing it, is a plus
What We Offer
- A genuine opportunity to grow with the business — hours can increase as our site pipeline grows to be discussed, with further hours available for those who take on more responsibility
