The housing firm, that was originally based in Queensway near the Hemel Hempstead old town, moved to its Maylands offices back in December 2009.
The company made the decision due to wanting a larger premise, and the number of homes owned and managed by the charitable housing association has doubled from 3,300 to 6,600 in total.
Hightown’s turnover has also trebled since the move.
Hightown’s Chief Executive, David Bogle, said: “Looking back, the move to larger, more modern offices in Maylands enabled us to grow our operations. But we could not have achieved so much without the hard work, loyalty and commitment of our staff for which I am most grateful.
“We hope to continue our work in partnership with local authorities and other statutory authorities and deliver many more affordable homes and support services over the next 10 years.” He said.
Hightown operates across Hertfordshire, Buckinghamshire, Bedfordshire and Berkshire but remains committed to its long-term mission of building new affordable homes and providing high quality housing and support services.
In addition to its social landlord work, Hightown provides care and support to vulnerable and disabled people in 85 projects.
