An architect's canalside townhouse is for sale at Union Wharf in London

Curving glass bricks and porthole windows reference this Islington townhouse’s canalside setting, while its sleek glass rooftop addition has views across Regent’s Canal.

Located at Union Wharf, the London property was initially used for light industry and converted in 2001. Its facade features blue bricks and a swooping wall of glass blocks that diffuses light into the interior while screening inhabitants from the street.

The Modern House has listed the three-bedroom townhouse for £2.25m. Its piece-de-resistance is a glass sunroom by TPM Studio that perches atop the building and opens onto a roof terrace with views of the canal and the city skyline. This aerial oasis is planted with silver birch, olive trees, grasses and flowers enveloped by a crisply rendered parapet wall.

The London property has undergone a top-to-toe internal refurb courtesy of its current architect owner, with living spaces stacked on top of each other. A striking all-black kitchen by Roundhouse contrasts the otherwise neutral colour palette, with polished concrete and wooden flooring, raised skirting and exposed timber adding texture.
