The agency won the account following a competitive pitch, and has been tasked with advising on media strategy and generating news - particularly around the town's official anniversary date, 23 January.
Revealing the "real Milton Keynes" by looking beyond stereotypes associated with the town will be a focal point of the brief, Houston PR managing director Hamish Thompson told PRWeek.
"It is the perfect opportunity to raise awareness of the many achievements of Britain's most famous New Town in civic life, urban design, culture and technology and set out the Council's agenda for the future," Thompson said.
The agency will also generate coverage around several "high-profile" community events throughout the course of the year, added Thompson.
Milton Keynes is widely known for its grid-style layout, as well as the creation of its football team MK Dons in 2004 - the team was formerly known as Wimbledon FC but was controversially moved to the dismay of many fans.
Houston was founded in 2007 by PRWeek UK Power Book entrant Hamish Thompson, a former Dixons director of media relations.
