Called Hunsett Mill, the project involved extending the existing mill house by adding several volumes with pitched roofs uncurling from behind the original structure.

The following information is from the RIBA:

Hunsett Mill is a very specific response to a very specific space: an arcadian setting on the Norfolk Broads. The windmill and its out-buildings appear on jigsaws, postcards and chocolate boxes as a famous view from narrow boats. The new building is conceived as a shadow sitting within the site lines of the retained cottage so that the new building is invisible from that specific viewpoint.

The new building is clad in black, charred timber so that it is truly a shadow, with flush glazing that add to the sense of insubstantiality. The overall impact is very arresting - more akin to the response to a piece of art than to a piece of rural, domestic architecture.

The judges enjoyed the constant inventiveness of Acme's approach seeking new materials, using intriguing structural forms to create interesting forms, values and visual effects. The building is used as a weekend/holiday home by a number of families based in London and Hertfordshire. This allows the interiors to continue the inventiveness and drama of the exterior forms without too many domestic constraints.

The roof forms are particularly enjoyable, creating a series of linked gables that are asymmetric but rhythmic. Internally the structural timber slab is open to the rooms but further changes of angle are added to create a series of interesting spaces, with the first floor walkway to the bedrooms particularly special. The whole is consistently detailed and well crafted with interesting use of off-site construction.

Overall the restoration of the cottage and the new building, which are linked internally, is an exciting and intellectually stimulating response to the unique rural setting. A cultured client has given free reign to the innovation of his chosen architects Acme and engineers Adams Kara Taylor.

Hunsett Mill proves that good architecture can be delivered on a budget and that it can be achieved in the most restrictive of situations. The resulting project balances value and quality and is one that many people could aspire to.

Hunsett Mill on the Norfolk Broads by Acme architects has scooped the Royal Institute of British Architects’ (RIBA) prestigious Manser Medal 2010 for the best new house or major extension in the UK in association with HSBC Private Bank. The presentation of the award took place at a ceremony at the RIBA last night, at which the winner received an increased prize of £10,000 and a new specially commissioned trophy designed by artist Petr Wiegl from presenter, designer, author and host Kevin McCloud.

Acme architects has won the award for its arresting extension to Hunsett Mill, a nineteenth century Grade 2 listed mill keepers house on the Norfolk Broads. Building a major extension that more than doubled the size of the original house on a uniquely picturesque site was challenging. Acme created an extension in the form of a shadow of the original house, which the judges describe as “more akin to a piece of art than a piece of rural, domestic architecture.”

Speaking about the winning building Ruth Reed, President of the RIBA said:

“Hunsett Mill, like a lot of really good architecture, results from one simple, strong idea. Instead of creating either a pastiche of the Victorian red-brick cottage, or a self-effacing glass box, the architects’ truly inventive solution was to create a kind of triple-shadow of the original, in black charred timber, crossed by the shadow of the neighbouring windmill’s arms.

“A private house commission gives the architect an opportunity to get inside the ambitions of the client and produce a shared personal statement. It is a building type in which every detail matters and in which they matter to client and architect in equal measure. Houses like Hunsett Mill do not get built without the extraordinary faith in and commitment to the architects by their clients. The RIBA is grateful to HSBC Private Bank for its strong support of this award.”

Declan Sheehan, Chief Executive Officer of HSBC Private Bank, said:

“Private homebuilding and redevelopment is becoming increasingly popular with owners expecting more from their homes. Developing your own property means that particular expectations and potentially more difficult requirements can be met, as Hunsett Mill brilliantly demonstrates. As a bank that offers unrivalled property expertise for private clients, we are delighted to support an award that recognises superb design and innovation.”

The five other shortlisted houses were:

  • Bateman’s Row, London by Theis and Khan
  • Furzey Hall Farm, Gloucestershire by Waugh Thisleton Architects
  • Leaf House, London by James Gorst Architects
  • Martello Tower Y, Suffolk by Piercy Conner Architects with Billings Jackson Industrial Design
  • Zero Carbon House, Birmingham by John Christophers

Previous winners of the RIBA Manser Medal include Pitman Tozer Architects for The Gap House (2009), Rogers Stirk Harbour + Partners for Oxley Woods (2008) and Alison Brooks Architects for the Salt House (2007).

Judges for this year’s award were: past RIBA President Michael Manser CBE; HSBC Private Bank’s property expert Peter Mackie, Managing Director of its Property Vision subsidiary; architects Luke Tozer from Pitman Tozer and Deborah Saunt from DSDHA; and the RIBA’s Head of Awards, Tony Chapman.

    a ray of light for uk architecture!

  • Sean

    Love the interiors, especially the pine hallway shown in the fifth picture.

  • Flying Dutchman

    Awesome, looks so nice and quiet bye the river. Freshly modern imposing. Love it

  • henryep

    I grew up near Hunsett Mill and it was one of the most photogenic sites in Norfolk and one of the most famous. Although I like the new extension I think they have made a massive mistake, they should have left this quaint Norfolk house the way it was. I am a fan of modern architure but there is a place for it and this was not it.

    Norfolk Broads has lost one of its real gems.

  • gardener

    henryep… I think you are not right. I also know Hunsett Mill and it was in a terrible state. The architect did the right thing not only to introduce modern architecture, but also to renovate the mill and the existing buildings… Great job considering that it is such a young office…to me the site still looks very photogenic

  • henryep

    Gardener….I have to disagree. Hunsett Mill had a charm about it. It was an old building which may have been a bit 'wonky' in places but it was its charm and is the reason it was always on postcards and jigsaws. You only have to google Hunsett Mil to see what has been lost.

    I agree its a great building and looks good and the architects have done a good job but it just shouldn't have been there.

    • John M

      I don't understand – the original old building is still there – its in the photos above! The awful series of extensions were removed and when approaching this from along the river the modern extension is hidden behind it.

  • Bravo… A dream house

  • Maria

    I like a lot the aesthetic of this work, but I would like to know if is possible to open any windows of this house?

    • John

      Of course it is… They would be on the same system as the door… use your brain

  • I'd like to watch any photos of the interior with open windows, is it will be possible?
    Thank you for your answer.

  • Maria

    I'd like to watch any photos of Interior with open windows, thank you.
