Building work on part of a major Lynn regeneration project is set to be delayed after the original timetable was deemed impractical.
The fourth phase of the Hillington Square redevelopment is still expected to start early next year, as previously scheduled.
But bosses of Freebridge Community Housing have announced that stage will now be split into two parts, because of concerns over the potential impact of the work on residents.
Chief executive Tony Hall said: “This is a large and complex project and we want to complete it with as little inconvenience to our residents and the surrounding community as possible.
“By approaching the regeneration of Hillington Square in a phased way, it has meant that we have been able to learn from the work we have already done as each phase is completed.”
He added: “Splitting phase four into two new phases will help minimise the length of time that people will be affected.
“The additional changes will open up the estate and the enclosed green space providing residents with a better place for them to call home.”
Work on phase three of the scheme began in the spring and is due to be completed by the end of this year.
The next stage covers the area which faces onto Bridge Street, including Greenland House, Ladysmith House, Farrow House and Vicarage House.
But that section will now be redeveloped in two stages, with the first due to start in early 2017 and the second in early 2018.
The company says the move has been made because of the potential disruption for residents and the difficulties of getting the necessary equipment onto site to complete it in a single project.
The new schedule also includes plans to demolish 12 more properties than previously intended.
Six of those are in Vicarage House, with the remainder in a block where Ladysmith House and Greenland House meet.
The company said the change had been made in response to residents’ feedback on aspects of the project that had worked well so far. The demolished properties will not be replaced at this stage.
Once those works are completed, two more sections of the estate, close to All Saints’ Church, are also due to be renovated.
It is now six years since Freebridge teamed up with designers Wayne and Gerardine Hemingway to begin shaping a new 21st century vision for the complex.
The first stage of the £30 million project, Millfleet Court, was opened in November 2014 by the then housing minister, Brandon Lewis.
The second block to be renovated, now known as Valentine Place, was unveiled in January this year, after residents moved back into the building.
Freebridge says residents in the areas affected by the latest changes to the work schedule were notified of them this week.
