My space: Deborah Spencer, show director of DesignJunction I'm drawn to quirky, challenging spaces. When my husband, Sam, and I came to see this church conversion in west London, six years ago, I fell for it instantly. There are 22 flats in the building; ours is on two floors, up in the eaves. It has stripped-back areas, like this open-plan living space, and other parts with original 19th-century features. Our bedroom has exposed brick and an amazing stained-glass window. This space was originally bright turquoise and had horrible, dated laminate floors. We've redone it in white to make it seem bigger, with just a hint of pale avocado on the back wall. It has been an exercise in spatial design because of the slanted walls; we've chosen low chairs, an L-shaped sofa, and a table that can be extended. It's a flexible, sociable area, and I often work here; I started DesignJunction, a showcase of furniture, lighting and product design, from this table. It's a good base for making a feature of interesting design objects, which I just can't help collecting. Reflective surfaces are important in small spaces. This is the mirror ball light by Tom Dixon, the product designer, who I have worked with for years. It doesn't project a huge amount of light but I think it's utterly beautiful Teacups These ceramic cups are part of a huge collection of odd teacups - the cabinet in front of me is full of them. I find them in all sorts of places, from Dover Street Market in Mayfair to flea markets in different cities around the world. I'm someone who lives for that first cup of tea in the morning Chairs I have a bit of a thing about chairs. I like that idea that they are designed to give us comfort. This one is a Hans Wegner "shell" chair, from 1963. We've opted for lots of different ones around the table. The clear perspex Philippe Starck "Louis Ghost" design at the head of the table, is another favourite Ornaments This vase is from a brand called Moooi, which means "beautiful" in Dutch. I don't use it for flowers, it appeals to me as a sculptural object. The candleholder beside it is by Miranda Watkins, who works in pewter - she did one of my first shows, and my husband bought it for me DesignJunction runs from September 18-22, during the London Design Festival.
