78 Derngate is a Grade II* listed Georgian house in the Cultural Quarter of Northampton, England, originally built in 1815. It is noted for its interior, which was extensively remodelled in 1916 and 1917 by noted architect Charles Rennie Mackintosh for businessman Wenman Joseph Bassett-Lowke as his first marital home.
The rear elevation also features a striking extension with two elevated balconies which, in 1916, overlooked meadowland to the edge of Northampton. The design origins of this extension have been the subject of some scholarly debate and a myth of Mackintosh as a modernist pioneer in his late career has persisted. However, recent research suggests that Bassett-Lowke and Alexander Ellis Anderson (a Northampton-based architect who supervised the remodelling) may also have had a hand in the design of this structure as well as Mackintosh.
Between 1964 and 1993 the building was used by Northampton High School for girls, initially as offices but later as classrooms. In 2002 work started to restore the house to Mackintosh's original design. This work was under the direction of architects John McAslan + Partners and involved a team of specialist contractors for expert restoration, or replication of, the original features of the Mackintosh period scheme.
After eighteen months of restoration, the house was opened to the public in late 2003. Small group guided tours or self-guided visits are available and provide an insight into this stunning and unique example of a Mackintosh-designed house in England.
A supporting museum adjoins 78 Derngate and is housed in number 80. In 2003, the Discovery Channel aired a documentary series hosted by Eric Knowles titled The House That Mackintosh Built. The series followed aspects of the property restoration as it was in progress. In May 2007 a new visitors centre at 82 Derngate was opened to provide further facilities and exhibitions for visitors. This building, also restored by John McAslan + Partners, houses a restaurant, art galleries, meeting rooms, shop, visitor reception and administration offices. A regular programme of exhibitions and events is offered and an active 'Friends of 78 Derngate' group continues to raise funds for ongoing development of the project. On 3 October 2013, HRH Prince Richard, Duke of Gloucester visited 78 Derngate to commemorate the 10th anniversary of its opening to the public.
