New data has revealed a rise in the number of new-build homes in Mansfield.
Numbers are also up in Newark & Sherwood but down in Ashfield.
And industry experts have warned that a mismanaged Brexit could hit developers with labour shortages and higher material prices.
Ministry of Housing, Communities and Local Government data shows that 250 houses were completed in Mansfield in 2018, up from 210 the previous year.
In Newark & Sherwood, 430 houses were completed in 2018, up from 360 the previous year, but in Ashfield building rates dropped from 330 to 230.
The figures only include new homes.
In Mansfield, private developers funded 72 per cent of all new homes, the local council funded another 20 per cent and housing associations paid for the rest.
Private developers funded 96 per cent of all new homes in Ashfield and 93 per cent in Newark & Sherwood with the rest, in both areas, being funded by housing associations.
Polly Neate, chief executive of housing charity Shelter, said the Government needed to strengthen its efforts to meet its target of 300,000 new homes a year.
She said: “The fact housebuilding rates have picked up since the start of the decade is a welcome sign, but the Government still needs to make giant strides.
"To achieve this, it simply cannot rely on private developers alone – building social homes must be top of the agenda."
Alongside completed homes, in the last year, work started on a further 300 sites in Mansfield, 220 sites in Ashfield and 410 sites in Newark & Sherwood.
Nationally, new home completions are on the rise.
Stewart Baseley, executive chairman of the Home Builders Federation, put the increase down to the Government improving conditions for developers.
He said: "Successive governments have helped create a much more positive policy environment, that has allowed the industry to invest with confidence in the people and land needed to build more homes.
"All indicators suggest we will see further increases in output and planning permission for new homes.
"Unlike the second hand market, new home sales have generally remained resilient to the ongoing uncertainty, but clearly demand for new homes is reliant on a level of economic stability."
The National Federation of Builders, warned that a 'poorly managed exit from the EU will create labour and work shortages'.
Nationally house building has mostly decreased since the 1960s.
The early part of this decade saw house building at its lowest peacetime level since the 1920s.
