Figures from the Regional Health Board indicate some 300,000 patients visit National Health Service centres that are situated within residential buildings.
To be constructed in partnership with Lisbon Council, the first new health centres will replace the oldest and most run-down ones in the blocks of flats.
Construction of the 14 brand new centres starts this year and should be complete by 2020.
In a statement, Lisbon Council said the new buildings will be financed by the local authority, and it will also concede the plots of land on which they are to be built.
“It is the biggest financial investment in reinforcing primary health care in the city of Lisbon in recent decades”, the council explained.
Reports suggest some €30 million is to be spent on the new centres.
