Figures filed with Companies House yesterday show interior designer Candy & Candy, which designed the communal areas and many of the apartments at One Hyde Park, as well as managing the development, made a £499,730 operating loss in 2015, down from a profit of £482,717 in 2014.
Turnover increased to £6.6m, from £6m the year before, but cost of sales rose, from £2.7m in 2014 to £3.5m in 2015, while it took a £50,258 hit on disposal of its fixed assets.
The figures also showed remuneration to directors increased, from £625,000 in 2014 to £1.3m in 2015 - while the highest-paid director's earnings rose from £375,000 to £588,147.
Is this another sign London's ultra-prime developments have had their day? Candy & Candy lists further competition in the luxury design market as one of its risks - but recent research has suggested the popularity of luxury homes might be waning (although it's worth pointing out that C&C works on homes across the world - and has even done private jets).
To wit: figures by the Royal Institution of Chartered Surveyors (RICS), published earlier this month, showed prices in London's prime property market stalled in February. That was largely thanks to actions by the chancellor, who has, in recent years, put sanctions on foreigners buying homes within corporate envelopes and hiked stamp duty on the most expensive homes.
Meanwhile, in February, property services giant JLL cut its growth forecast for the capital's high-end homes, blaming a "diminishing appetite" for homes worth more than £2m on stamp duty changes.
"Transaction levels in JLL's [high end] offices fell by over 20 per cent [after new stamp duty rules were introduced]," it said at the time.
"This impact has been more pronounced for the highest value properties, with falls of up to 12 per cent for homes worth over £10m and as much as seven per cent for homes worth over £2m."
