Architectural proposals for a Pavilion & Green House for a Gothic Mansion from Humphry Repton's book 'Observations on the Theory and Practice of Landscape Gardening', published in 1803. Repton writes, ' At Plas-Newyd, where the house partakes of a Gothic character, I suggest the addition of a green-house terminating a magnificent enfilade through a long line of principal apartments.....The side window frames might be removed entirely in summer, making a beautiful pavilion at that season when plants being removed, a green-house is generally a deserted and unsightly object. The effect of this building by moonlight is shewn in the annexed sketch.'
