James and Katrin Gray live in Bournemouth on the south coast. James runs his own book distribution business and Katrin works for an investment bank. They used to live in an apartment on the second floor of a former Victorian hotel. But three years ago, James bought the top floor flat. It was originally built as a solarium for the hotel in the 1920s where holiday-makers could soak up the sun. Now James and Katrin plan to convert it into a modern, luxury penthouse. The first project was to build a large rooftop extension which became the main living area of the new penthouse. This steel frame structure was cleverly knitted between all the obstructions on the roof and leads out onto a fabulous roof top terrace with exclusive views along the coast.
