At Tamworth the planning consent also includes a 100-unit extra care facility and a local community centre alongside a primary school and sports pitches.
Hallam Land is now in advanced contract negotiations for a sale of the site to a major house builder.
At Fareham the site will also include an 80 bed care home, a two-form entry primary school, a community centre and a new country park which includes a 10 hectare bird reserve.
Hallam Land currently has active appeals on four other sites, totalling around 1,300 residential plots.
Tim Roberts, CEO at Henry Boot, said: “Securing planning consent for nearly 2,500 homes is a clear testament to our team’s expertise in unlocking complex sites for development.
“The approvals also signal renewed momentum in the planning system following the government’s reaffirmed commitment to removing planning barriers and tackling the nationwide housing shortage.
“It is a strong indicator that well-considered schemes in the right locations will be approved, and we expect strong buyer interest as we bring them to market, enabling us to unlock the value we have secured on behalf of our shareholders.”
