Mellish Court in Bletchley and The Gables in Wolverton have now been demolished, after Milton Keynes City Council found new and better homes for its previous tenants.
The demolition of 19-storey Mellish Court was completed earlier this week as contractors took apart one floor at a time. The Gables in Wolverton was taken down earlier this year.
Around 95% of the materials from both buildings will be recycled.
Some clearance work remains on Mellish Court as the contractors remove the foundations of the building.
MK City Council will shortly start conversations with local people about how best to use the site in the future.
In 2021, MK City Council acted quickly to rehouse almost 200 families from The Gables and Mellish Court after it determined work on the 1960s buildings was needed to meet new fire safety standards. It subsequently decided to knock down the buildings, its last two tower blocks in MK.
Cabinet Member for Adults, Housing and Healthy Communities, Cllr Emily Darlington said: “Finding new and better homes for our tower block tenants has been our initial priority which we managed to do quickly. Now that the demolition is completed for both blocks our focus is on making the best use for the sites.
"We’ll work very closely with people living near Mellish Court and The Gables to create new healthy and happy neighbourhoods in these areas."
