Invercargill man Andy Blay is about to dismantle his 30,000 Lego piece replica of the building which is the centrepiece of the hit show Downton Abbey.
But he will rebuild it to show it off to Lego lovers from far and wide.
Mr Blay said all the members of his family were fans of the show and he wanted to do something to celebrate that.
He had done Lego sets when he was a child but left it behind as he grew into a teenager. But when his daughter was about 5 she started getting into Lego and he helped out.
Now his daughter is 20 and he is still working on the pieces.
He had created a replica of the Rainbow Warrior boat along with a World War 2 scene and now the mansion.
He decided last year to have a go at replicating the estate building used in the show by the Crawley family. It is actually Highclere Castle in Hampshire, England.
Mr Blay said there were a lot of tan pieces needed, such was the colour of the mansion.
"Obviously you can’t go out and buy the set. So you have to have pieces you have picked up over the years. And everything has to be to scale so you work out the size of the figures and then everything goes from there," he said.
"I would have spent $1500 to $2000 on pieces for this. They came from all over the show.
"You do have to have a lot of patience. A lot of people just build from sets but that is where all the pieces are just in front of you. This is nothing like that," he said.
"You are constantly running out of parts and you have to wait for them. So yeah, it takes time.
"For this latest one a whole lot of parts came from Japan. They were limited runs. I needed 100 or them and he had 120. I got the whole 120."
He said the build had come together well and he was really happy with it.
Mr Blay, 49, used to be a builder but he has muscular dystrophy which has slowed him down. He remains positive.
He is set to show the mansion at the Christchurch Brick Show this weekend. He will take the replica down over the next couple of days and then put it up when he gets to the show.
"It is the biggest Lego show in Australasia. They had 22,000 there over two days last year.
"I won a people’s choice award there, but it is not really me. I don’t do it for the awards. I do it because I like doing it."
