Smart design is what you need to create seamless spatial flow from indoors to out. A slim stainless steel slot drain is exactly what artist and interior designer Laura Gompertz chose when she renovated her kitchen and tired outdoor area.

“Basically, the decking was washing away,” she says, “and I wanted the effect of the inside and outside looking similar.” Laura specialises in kitchens, but has on more than one occasion found it natural to extend her designs into the garden. “It’s sort of like the same space,” she says.

The importance of slot drains in Indoor Outdoor spaces

Although the fall in the paving runs away from the back of the house, a belt-and-braces approach is vital where, like this, the floor inside and paving outside are on exactly the same level.

Laura chose our stainless steel slot drains. “They’re nice and discreet, making it look like one room. Although we’ve had some very heavy rain since we installed the stone, it’s never washed in.”

With the inspection unit tucked tidily into the corner near the outside tap, the patio slot drain shows only as a neat, thin line, parallel with the door runners, creating virtually no interference as the eye travels to the far end of the garden.

To aid drainage further, Laura also included an unpaved 3-4 inch perimeter around the edge of the garden, neatly finished off with black and white pebbles for weed suppression.

Paving Choices

Indoors, the kitchen had been tiled with filled travertine. “I chose Jura Beige for the outside. It’s beautiful with the fossils in it, so I made the most of the opportunity to use it.” The soft beige colouring tones with the Travertine, while both offer an interesting surface texture, the shapes of the fossils in the Jura limestone add dramatic character to the paving area. A narrow slot drain is an ideal choice where you don't want to distract from the beauty of your paving.

Pre-sealed stone for easier maintenance

Laura had the limestone pre-sealed by London Stone – something that she found crucial. “That’s a real plus for London Stone. There are very few suppliers that will seal stone before it arrives. And you have to ask; when are you ever going to get round to sealing it yourself? Now, it needs the odd brush and wash down - I just hose down gently to clean.”

As you can see in the picture, eighteen months on from completion, stone and stainless steel slot drain certainly continue to look smart!
