A map shows where hundreds more homes could be built across Sussex each year to meet new government targets.

Housing Secretary Angela Rayner will make local housing targets mandatory again as she unveiled an overhaul of England's planning rules to help deliver Labour's promise of 1.5 million new homes by 2029.

Across England, councils will now have to plan for around 370,000 homes annually, instead of the previous 305,000.

The new targets will see hundreds more homes built each year in Sussex than previously planned.

Ms Rayner said: "Our decisive reforms to the planning system correct the errors of the past and set us on our way to tackling the housing crisis, delivering 1.5 million homes for those who really need them.

"And something I am personally proud of, our new flexibilities for councils will boost the number of social and affordable homes and give working families a better route to a secure home."

The reforms also make explicit that the default answer to brownfield development should be "yes" and promote housebuilding at greater densities in urban centres like towns and cities.

However, because there is not enough brownfield land in the country to meet housing needs, the government will allow the targeted release of so-called grey belt land, which includes disused petrol stations and car parks on parts of protected land known as the green belt.

Any green belt land released will be subject to "golden rules" to ensure the development has 50 per cent affordable homes with a focus on social rent and has access to green spaces and infrastructure such as schools and GP surgeries.

The method for local authorities to calculate how much land they must allocate for new housing, which relied on data from 2014, will be updated to ensure stock is boosted in every part of the country.

"Rather than relying on outdated data, this new method will require local authorities to plan for homes proportionate to the size of existing communities and it will incorporate an uplift where house prices are most out of step with local incomes,” said Ms Rayner.
