The Henry Moore Foundation – celebrating 40 years this year, with a series of special events – has unveiled its redeveloped estate, Dane Tree House, in Hertfordshire. The Foundation is housed in Moore’s former home and studios in Perry Green, a 70-acre site with landscaped gardens designed by Moore’s wife, Irina Moore.

The new buildings – including a new library, cafe, shop and archive facility – were executed by British firm, Hugh Broughton Architects. The design ‘maximises views of Moore’s sculptures, set in the gardens’, says Hugh Broughton, with generous glass giving onto the rural surroundings, a landscape in which Moore found considerable inspiration for his works, and where sculptures such such as Sheep Piece (1971-72) and Reclining Figure: Draped 1952-53) are now displayed.

The Foundation reopened for the Easter weekend with an exhibition, ‘Becoming Henry Moore’, that goes back to the beginning, reviewing the artist’s early work and inspiration, which he found not only in the undulating curves of the countryside, but in artists like Picasso, Hepworth, Michelangelo and Epstein – all on view until October, alongside rare works by Moore himself, such as a collection of drawings from the 1920s that clearly show his singular style emerging.

Having already completed renovations on the sculpture stores at the Foundation in 2011, Hugh Broughton’s latest developments will improve the scope of the Foundation. Other major improvements include an extension to the library, revamped with oxidised steel panels, that also address the optimum storage conditions needed to safely store the Foundation’s valuable books, documents, and photographs.

There’s an emphasis throughout the design too on sustainability; a shared ground source heat pump will cool and warm the two buildings, and the use of timber implies aesthetic harmony and neutrality, in the same way Moore’s sculptures serenely inhabit the outdoors. Working with demanding atmospheres and unusual environments is something London-based Hugh Broughton are particularly good at – the firm is behind the award-winning Halley VI British Antarctic Research Station and the Juan Carlos I Antarctic Research Station (which is currently in construction).
