Spiral Staircase in Chiswick Refurbishment
Our client lived in a duplex apartment in Chiswick, with a basement below that was a separate dwelling rented out to someone else. When the basement came up for sale, he bought it with plans to connect it to his home and create a three-story property, likely returning it to its original layout.
He originally contacted us about the stairwell size needed for a spiral staircase, as space was tight and a spiral seemed the best option. While the opening width was ideal, the depth was limited, so we designed an 1800mm diameter spiral with a shortened triangular platform, shifting the center column away from the rear wall.
The platform also served as a walkway between two rooms, and using a glass floor helped bring much-needed natural light into the windowless basement.
For the finish, he chose special boxed walnut treads over steel with brushed steel balustrades for a modern yet understated look. The result was a stylish connection to the basement that brightened and enhanced the living space.
