“Farmhouse Fixer” (HGTV — series premiere, March 3)

Jonathan Knight, best known as one of the New Kids on the Block, has the “right stuff” to host this new makeover series, in which he offers his advice on meticulously restoring centuries-old New England farmhouses that deserve a second chance. Each of the six episodes in Season 1 features Knight, who has renovated more than 200 houses, preserving the home’s original craftsmanship and historic charm, while modernizing room layouts and updating interiors. In the premiere, designer Kristina Crestin helps Knight refurbish an 18th-century New Hampshire farmhouse.
