Even before the Regency, house renovation was becoming quite the thing. Horace Walpole took a nondescript cottage and redid it from the ground up to make it into the Gothic Revival villa Strawberry Hill. Some time after him, the first Duke of Northumberland renovated Syon House, but couldn’t finish because he ran out of money. You’d never be able to tell to look at it (yes, I’ve visited it; it’s lovely).
Letter-writing was a favorite Regency pastime — albeit a pricey one. The recipient bore the cost of delivery, which was calculated by the distance the courier had to travel. Long-winded epistles faced surcharges: the cost doubled for a second sheet of paper. People became quite crafty in using every bit of space a sheet of paper afforded. Some ladies were known to write horizontally, vertically and diagonally across the page. Envelopes didn’t exist, so letters were folded and sealed with a dab of melted wax.
