Midlothian Council is to spend £11.5 million rebuilding the houses set for demolition at the gas-hit street in Gorebridge.
Councillors today decided that houses in Newbyres Crescent should be rebuilt at an estimated cost of £11.5 million, with gas membranes installed in the properties.
All 64 homes on Newbyres Crescent are currently being evacuated due to dangerously high levels of carbon dioxide on the street, which were first discovered in September 2013 when six people required hospital treatment. More than half the homes there are now empty.
The other option put before councillors today was to, at a cost of £7m, demolish all 64 properties and market the site as a potential development site.
Gas was first discovered on the street in September, 2013 when two properties were evacuated after six people required hospital treatment.
