Callender Howorth Interiors

Callender Howorth provides interior architecture, interior design, renovation and project management for residential and commercial properties. Its work includes full interior schemes, styling, bespoke features, furniture and lighting. The team works on homes and commercial spaces in the UK, Europe and North America.

Founded and led by Mark Howorth in 1997, the practice has a multidisciplinary team of interior designers, interior architects, stylists and project managers. It works with clients to develop a design around their preferences, practical needs and the way they use the space. English and French are spoken.

Projects begin with briefing and concept design, then move through detailed design, procurement and project delivery. The team prepares design drawings, helps select materials and furnishings, manages tendering and coordinates contractors and suppliers. During construction and fit-out, it makes site visits and carries out quality checks, keeping clients informed of progress.

Its interior renovation service covers residential and commercial properties, from planning and costing through to procurement and construction oversight. The practice reports work in Central London, Paris, the French Riviera, Saint-Tropez, New York and Los Angeles.
