The construction of attractive and decorative and cleanly cottages for the estate workers, called cottages orné, according to the principles of William Atkinson, have been thoroughly blogged by Kathryn Kane here and here and here. Worth a read, so do go take a look if you have not already done so. The idea of nice cottages was so popular that Ackermann's repository published several ideas of such cottages. And I have to say some of them were rather larger than what I would call a cottage; though as Kat points out, the conceit of having a large 'cottage in the country' was sometimes one that attracted wealthy men too, whose sensibility to aesthetic pleasure probably exceeded their common sense. I do not apologise for showing a fairly wide selection before moving on to specialist buildings.
I doubt the tween maid felt much domestic felicity about looking after the master in his rustic conceit.
However, enough about cottages ornés;and on to the specialist buildings Ackermann's considered essential to illustrate.
First, on entering the estate, the estate gatehouse or lodge is required both to show status and to indicate where the entrance is [having driven around the wilder countryside frantically looking for places, believe me this IS necessary; you do not want to get stuck in the muddy ruts of any old farm track and spoil your muslins with muddy splashes when you have an invitation to a house party with Mr and Mrs Fitzwilliam Darcy!]. The gatehouse needs a gatekeeper and possibly his wife to turn away the unwanted callers and direct those who are going in the right direction.
And as cleanliness is next to Godliness, one must have the ornamental bath in the garden, since once the difficulties engendered by difficult to remove dress and powder in the hair were no longer in force this impediment being removed, it is probable that baths will be employed by us as common and frequent sources of innocent pleasure as well as for medicinal relief. And a relief to the noses of all around them too... The writer pontificates about Roman baths for a while and suggests warm as well as cold baths. I bet the servants loved trekking across to the bath house to stoke the means of heating the warm bath.
For the comfort of the family and all those ice creams and sorbets, the ice house of course on which I have already written here
Oh but to make those ice creams, the cream is needed - so of course a dairy, served no doubt by a buxom dairy maid and no cows in sight, or perhaps in a field to look attractive and far enough away not to smell at the house guests, or look menacingly large at the ladies.
And of course all those tenants and estate workers in their cottages ornés will need a bailiff to make sure they pay their rent, don't damage the nice new cottages, nor moon at the master's company.
