This week on Dezeen, a rural house in Northern Ireland by McGonigle McGrath was named as the RIBA House of the Year, and Glenn Murcutt's MPavilion was unveiled in Melbourne.

On Wednesday, House Lessans was revealed as the 2019 winner of the Royal Institute of British Architects (RIBA) House of the Year prize, chosen from a shortlist of seven architect-designed homes in the UK.

The dwelling, which McGonigle McGrath built on the site of an old farmstead in County Down, was referred to by RIBA president Alan Jones as "a dream home" executed with "incredible clarity and restraint".

This week also saw the opening of Pritzker Prize-winning architect Glenn Murcutt's minimal MPavilion, which will be installed in Queen Victoria Gardens in Melbourne, Australia, until March.

Murcutt, who was chosen as the sixth designer for the annual commission in February, designed the pavilion with a pared-back, linear form and slender roof that glows like a "lantern".
