From a knitted royal family to a Wedgwood bust of Prince Charles, no item is too big or too small for 74-year-old Margaret Tyler to add to her royal memorabilia collection. Arguably the royal family's biggest fan, her collection is spread over her entire London home. We paid her a visit.

So where did it all begin? "My parents were great royalists," she explains. "When I was eight the king died, and when I was nine Elizabeth was crowned. I just loved everything about the coronation." So much so, she has a whole room dedicated to the monarch.

The 'Jubilee Room' is full to the brim of items celebrating all of the Queen's anniversaries. Commemorative pieces for the 1977 Silver Jubilee sit along the wall, which has the most items out of all the celebrations. At the back sits a model of a royal carriage. "There was an exhibition at Windsor, and they were selling stuff because their lease had come to an end. I bought so much I had to have a furniture lorry to bring it all back. It was an expensive day," Margaret says.

Also hidden away in this room, on the centre table, is Margaret's first ever collector's item. A small glass dish that cost just 2.5 pence at a school bazaar. "I spend more than 2.5 pence now," explains Margaret. "I'm really lucky that a lot of my Christmas and birthday presents from the children are royal related. No gloves or handkerchiefs for me."

What was once the dining room is now an area focused on William, Kate and their three children. This section includes £100 dolls of the royal couple from Hamleys and an engagement photo that's one of Margaret's favourites. She even has an exact replica of Kate's engagement dress, which retailed for £385. "It's by Issa and I was on a waiting list, see if you're on a list you're okay. I think she looked smashing in it, especially with the ring," says Margaret.

Margaret tends to head to most royal occasions if possible. "I've met most of them. The Queen Mother I used to give flowers on her birthday and I've met Prince Charles and Prince Andrew. The Queen I've met four times," she says.

Her favourite royal of all is the late Princess Diana. "She came to our local hospital and I was wearing this rosette. I gave her a rose and she spotted my rosette. She threw her head back and laughed and said that I had it bad. It was amazing," says Margaret. "I was called her number one fan when she was alive."

In fact, Margaret is such a huge fan that she has a whole memorial room dedicated to Princess Diana.

The room was built 20 years ago, and Margaret commissioned stained glass windows for the space, with the one of Kensington Palace taking over 200 hours. "I wanted the room to be all about her," explains Margaret.

"The painting of Diana and the two boys is my favourite out of the whole collection. So I put that in the room first and added everything else around it," explains Margaret. "I think it's a good likeness of their faces, as they are quite hard to paint."

This Wedgwood bust of Prince Charles is one of the most expensive things in the collection, costing £1,200 ($1,600). "There were only 25 made for his wedding to Diana. It's made out of Basalt from Scotland. It's a good copy of him with the wavy hair and when he becomes King it'll be centre stage," she says.

Even outside Margaret celebrates the royal family, adorning her home in plaques and even a royal baby sign. "One lady thought I'd had a baby and knocked on my door to say congratulations. I had to tell her I was too old to have babies and that it was for Prince Louis," she laughs.

Brand new in her collection are these ‘fun dolls’ that came all the way from America. "They were in a Sunday newspaper, but I couldn’t pay for them because I don’t have a computer and you had to pay in dollars, so my son got them over here in a week," she explains. "People want me to take them to the wedding, but I’m not sure there’ll be room for them in the crush," she adds.

So how does one add to a collection this vast? "A lot is from the shops on Buckingham Parade Road. They have the Queen’s gallery and two other shops. If something comes in they ring me and keep them. There’s one lady that walks me around the shop and shows me all the new stock." This set is one of the newest additions to the house, which is the official china for the upcoming royal wedding.

She also goes to Covent Garden most Mondays to see what they have on offer. "I had this Prince George tea set made in Covent Garden. I couldn’t find one in the shops of him and he’s on every bit of this set, the milk jug, cups and even the saucers." She also gets items coming to her from well-wishers. "People just send me things. If they don’t know what to do with it they leave it in a box on my doorstep."

She's up at 4.30am every day checking the newspapers and watching royal correspondents on TV. "I'm also trying to do a scrapbook but it hasn't got off the ground. I have the cuttings but no space as the tables only get cleared at Christmas," Margaret explains.

With the royal wedding just a few days away Margaret is in full preparation mode to go to Windsor. "It'll be a fun wedding. I'm going to go down, but you have to be there for 9am, and it's a long way. I used to have tea parties for royal occasions but have run out of room."

So what are Margaret's top tips for others looking to start such a vast collection? "I frame everything that can be moved," she says. "I would also say buy what you like and make sure you enjoy what you do. I love it, live it and breathe it."

It's taken the royalist 40 years to grow the collection to the size it is today and she is finally starting to run out of space in her home. "The collection keeps me off the streets," she says. It's hard to put a price on it but the collection is insured for £40,000 ($54,000).

So what's next for the royal fantatic? After the royal wedding she is going to relax and watch Netflix drama The Crown as "this wedding has been really busy". When asked what she'll do if she gets any more memorabilia, she replied "That's my next problem". But this remarkable royal fan has no plans to stop collecting anytime soon.
