Helena Partnership green space service will manage the upkeep of around 13,500 council homes from their "Passivehaus". The 30-strong team will be able to teach locals about horticulture and other green issues on site.
"It's a horticulture and landscape facility," said green-space manager Liz Somner. "We want a building within an estate so people feel ownership. Nearby land will be used to experiment with perennial mixes and to grow food.
"Raised beds will be used by elderly people and those with disabilities, and there is scope there for an orchard and wild flower garden."
The Merseyside social landlord said its £420,000 Passivehaus would be one of only a handful in the country, offering 90 per cent savings on heat.
This project is part of a wider green strategy that includes street clean-ups, creating allotments and making hanging baskets to encourage communities to take more care of their neighbourhoods.
