The circa early 1800s building at 1 Thompson Square, overlooking the Hawkesbury River and the new Windsor Bridge, has already garnered interest from potential buyers in the short time it has been on the market.

Michael Bennett, principal of the Bennett Property Team, said "people from far and wide" had enquired about the "hard to find" property.

"We've had a lot of interest from people wanting to move from Sydney since the Covid-19 crisis, and there's certain people who just want to buy historic homes," he told the Gazette.

"You really only take care of old homes - you're part of the chain of owners in history."

The home offers five bedrooms, two bathrooms and multiple car parking spaces (one undercover), and is zoned for residential and commercial use.

It has a stunning entry foyer with majestic staircase, timber kitchen with stone benchtops, original floorboards, nine fireplaces as well as air conditioning, a hand-carved sandstone basement and wine cellar, and an outdoor entertaining area with an authentic pizza oven.

Mr Bennett said the building had been fully-restored by the current owners - one of whom is a builder - since it last went on the market.

"The downstairs area is really surprising, it's like going into an the kind of old English-style pub that you'd find around The Rocks in Sydney," he said.

The original basement began life in 1819 as The Lord Nelson Inn and - in addition to the wine cellar and tasting room - features a poker room, store room, lockup garage, shower, toilet and laundry.

Mr Bennett said it was the perfect home for artists.

"[The current owners'] boys were in a rock band and they played down there - it's completely soundproofed," he said.

"It's a great area that would suit anyone who wants to play music or use it as an art studio, or work from home. It's like being in another world."

The block is 645 square metres and features a chook pen, vegie patch and immaculate low maintenance gardens.

Inside, there is a huge dining room, a craft room and a music room, 12 inch skirtings, 6 inch architraves, original doors, ornate ceilings and cornices, and a claw foot bath.

"It's really something special," Mr Bennett said. "This is tightly held, a rare opportunity."
