Annemarie St Vincent Farr likes to make things. Whether it’s from her life as a painter/decorator, as a set and prop designer, or as an events stylist, Annemarie’s style and joie de vivre is written all over her rather astonishing Hastings home.

The first thing that strikes you as you approach the terraced house is its bright pink front door. It immediately makes you smile and you get the sense that guests are warmly welcomed into this house on a regular basis.

“It’s a party house,” confirms Annemarie as we stand in her blue and pink kitchen, a space that immediately reminds me of Mexico. “I love having people round, and my home reflects that.”

There is a wonderful sense of not-giving-a-damn that runs across every square inch of this four-storey house – which is very much in the riotous free spirit of the seaside town she moved to from Lewes four years ago.

“It’s a place full of people like me – arty, creative and a bit wild, many people here have a similar history to me as well. I’m never go to leave this place, it suits me.”

“It’s my Downton Abbey room, where me and my girlfriends come and have a laugh with a glass of red wine”

Annemarie’s home is above all about colour. Pinks, greys, reds, purples, greens, blues, browns, silver and gold…oh and pattern and embellishment and kitsch and flowers and birds and butterflies and a whole heap of fun and laughter. This is not a house that takes itself too seriously and every room within it is packed with life, almost like a tangible autobiography of its owner.

Annemarie and I are sitting in her top floor attic conversion that she has recently made into a bedroom for her granddaughter.

“Any colour can work as long as it’s beautiful,” she says, “and I don’t care about rules…I put it together and it just seems to make sense.”

Could this room be more of a fantasy room for a small girl? There are baby lambs and cartoon mushrooms across the floor. There’s glitter and fake flowers, Designers Guild fabrics, tapestry cushions and an entire wall covered in a trompe l’oeil wallpaper of red upholstered leather. Seriously, what’s not to like?

“This is my homage to Versailles,” says Annemarie casually as we walk down to the first-floor landing.

Decorated in cerise pink, dark grey with gold detailing, it’s a look she copied from the original Sun King’s palace in France. Transported to a Victorian terrace in Hastings it somehow works. A series of gold-framed looking glasses staggered across the walls, completes the look – Hastings’ very own Hall of Mirrors.

Keeping things French, a Christian Lacroix butterfly wallpaper runs the length of the stairwell, from the top of the house to bottom, the grey background upstairs, matched with hot pink painted walls above the dado, transforming to turquoise on the lower ground floor.

In the two first-floor bedrooms Annemarie has created spaces in which every corner tells a story. “I’ve just had a big change in my life, so my bedroom has been painted pale grey, like a new canvas. However, I could never cover up my Vivienne Westwood wallpaper, no matter what happens in my life.”

Annemarie gestures over to a wall covered in the designer’s signature punk tartan fabric. Indeed the whole house feels like somewhere that Dame Vivienne would feel right at home, with its blend of 50s nostalgia, flea shop mementoes and found objects, discovered all over the world.

In both bedrooms there are cabinets of curiosities – memories for Annemarie of her life. Glittery platform shoes that she bought in Brighton and little Russian dolls, tiny iconic statues of the Virgin Mary and Frieda Kahlo style floral headpieces.

In the main bedroom is a series of pop art pieces by Tiff McGinnis (grandedame.co.uk), a friend with whom Annemarie co-owns her nearby beach hut.

Keeping the collaborative spirit alive, in her guest room, decorated in wallpaper by Pip, a fabulously kitsch Dutch brand, are two bed side tables and a cabinet decorated with third eyes, made by her friend Loulou Cousin another of the beach hut co-owners.

What is emerging as we walk around is a home of collaborations and of sisterhood. A large Warholesque print of Jackie O sits proudly above the fireplace in the guest room. I ask Annemarie if there was any connection with the former First Lady?

“Oh yes, my mum was nanny to the children of Jackie O’s daughter, Caroline Kennedy. That’s how my mum always had her hair, just like Jackie O.”

In a house that seems to be so full of life, spirit and memories, it is Annemarie’s skill as a decorator and a decoupage artist that truly sets it apart. On walls, doors and cupboards, motifs and off-cuts of wallpaper have been artfully designed and manipulated into place.

From her bathroom, which is the antithesis to bland hotel bathrooms – a dreamscape of azure blue and florals –  to the lower ground floor kitchen, Annemarie reveals her abhorrence of anything white or functional. The fridge freezer, camouflaged in eau de nil, is decorated with motifs reappropriated from vintage posters.

How do you paint a fridge? According to Annemarie it’s a layer of undercoat, any paint you like on top and then several coats of varnish on top of that. The effect is amazing and the large hulking white fridge has vanished.

The kitchen cupboards have also been painted and wallpaper has been cleverly inserted into door frames wherever possible. “I love wallpaper, if my granddaughter stood still, I’d wallpaper her!”

Large classical busts from May’s Antiques in Lewes sit side by side with vases and jugs of both fresh and fake flowers. In the centre is a kitchen island picked up from Ardingly Antiques Fair, on the walls are prints by local artist Claire Fletcher. Bowls of fruit and vegetables and a series of mosaic panels, designed and made by Annemarie, also jostle for attention. It’s not really a kitchen, more of a party preparation area, although Annemarie is a devoted cook.

“I’m a vegan,” says Annemarie, “so I have to be a good cook. I spend a lot of time in this room, so I wanted it to be at the heart of the house.”

Next to the kitchen is a snug, resplendent in gold and pink Designers Guild wallpaper. Annemarie’s Liverpudlian nana’s 1950s bar has been given a makeover with wallpaper and trimming and is filled with silver sequin mirror balls. On the walls are felt flamingos from Shop House on the High Street.

A large and inviting raspberry velvet sofa, bought from Raft in Brighton, makes this room a place where you would want to put your feet up with pina colada in your hand and a double bill of Gone With the Wind and Hairspray on the TV.

Back on the ground floor Annemarie takes a seat in her living room, a stylistic departure in tone, if not in impact, from the rest of the house.

“This is the very first decorating that I did when we moved in,” she says pointing to a wall covered in a forest scene populated by deer. “I found it in a Mexican shop in Amsterdam called Kitsch Kitchen, it’s fabulous isn’t it?”

As I peer at tiny Babycham deer sculptures scattered across the mantelpiece, my camp-o-meter goes off the scale

The room is covered in a trompe l’oeil wood panelling wallpaper, designed by an art student that Annemarie discovered. “I thought I had bought five rolls,” laughs Annemarie, “it was in fact five drops. I needed eighteen for the room. That was an expensive mistake and I had to save up and get some more, but luckily I’ve made the pattern work all the way around the room.”

And work it does. The matt finish of the paper mimics the library or drawing room of a grand house. “It’s my Downton Abbey room, and it’s where me and all my girlfriends come and gossip with a glass of red wine.”

On the table are a series of clocks and against the wall are a stack of vintage suitcases that Annemarie used for the set dressing for her stand at Goodwood Revival (every September). Where does she buy her antiques?

“Oh all over the place, in Hastings I love Up the Garden Path, I go to the big boot sale in Icklesham and all over in Bexhill-on-Sea. In Lewes I go to May’s Antiques.”

Annemarie tells me with delight about the beach hut that she has just started renting with a friend. We drive down to the nearby beach and despite it being the first day of heavy rain in weeks, a bolt of sunshine leaps out as soon as Annemarie opens the hut’s wooden door.

Pink, blue and red walls and floors are decorated with bunting, trimmings, rugs and throws, all of which shout of a good time to be had by the seaside.

Loulou Cousin, the maker of the furniture both at the hut and at the house, arrives. I ask her about the little animals that line the hut’s ceiling joists and shelves. Are they voodoo dolls? No, they are psychedelic acid bunny rabbits she says, offering me a chocolate Hob Nob as the kettle gently bubbles away on the gas camping stove.

The beach house has been a fun new project and now, for personal reasons, it is time for Annemarie to move on again with her home, as she is putting the house that she has lovingly crafted over the past three years, on the market.

“So much of the furniture has been decorated to match the walls and vice versa that it would seem a shame to split them all up, so I am more than happy to offer some of the pieces to the right buyer.” (Contact Knight & Knoxley, Hastings.)

However, as the cheerful colours of her house attest, Annemarie is most definitely a glass half-full person and she is already conjuring up ideas for her next home.

“I’m thinking about large blown-up images on the walls, I mean like really big…”
