New homes to be built in Lincoln will be the first in the city to boast 100 per cent energy efficiency.
A total of 13 detached properties will be built on land by Albion Close, near Long Leys Road.
The homes, which the developer says will have the "highest environmental performance", will be the first of their kind to be built in the city.
The project will include a mixture of three-bedroom and four-bedroom houses, all with garages.
It comes after proposals were approved by the planning committee at City of Lincoln Council.
An action group opposing the plans had been set up but a passionate speech by its leader Jacqui Briggs during the meeting couldn't prevent the plans being passed.
Planning committee member Ron Hills said: "Of course there will always be some resident who oppose these kinds of projects.
"But it is a good project on the whole and one I have to support."
The work is set to start next month. It will be completed within 18 months.
Substantial tree planting on the site has been proposed as well as the creation of new wildlife habitats.
The green buildings will also be positioned to maximise solar energy.
Four councillors voted for the plans, while two voted against and three abstained.
"There are a lot of residents who oppose these plans and of course we are disappointed with the outcome," said Mrs Briggs.
"There are quite a few children who live down Albion Close and it will affect them as it will the older people, too.
"I appreciate it's difficult for the councillors and I believe the fact there were more councillors who didn't vote for it than did is a moral victory."
