Our refurbishment of the Common Room at the Oxford university Department of Education opened this week. The space has been re-imagined as a ‘garden room’, enhancing the qualities of the 1960s building and better connecting the room to the garden outside. For full project details see here.
Oxford Common Room on Site
Work is underway on our refurbishment of the Common Room at the Department of Education at Oxford University. This is the final sample board. The design aims to improve the social and learning environment by enhancing the qualities of the 1960s building and better connecting the room to the garden outside. Completion due in September, in time for the autumn term.
Air-tightness achieved at Mendip Passivhaus
Works are proceeding quickly on site on our certified Passivhaus project in Somerset. The first phase of spray-insulation has been applied and the Internorm windows were installed in August. The first air-test was carried out this week and achieved 0.36 ACH, well below the Passivhaus requirement. Congratulations to our hands-on client! See here for project details.
Patrick McEvoys's bench in the London Festival of Architecture
We're delighted that Patrick McEvoy, who works in our London office is one of ten winners in a competition organised by the London Festival of Architecture to design a bench for a public space in the City of London. Installed in Jubilee Gardens, Houndsditch, the bench is a memorial to a dog called Geoffrey Barkington. Cast in self-compacting concrete the bench weighs over a tonne.
The Dundon Passivhaus is included in the latest edition of Country Living Modern Rustic, and in the July issue of Red, featuring the wonderful photographs of Polly Wreford.
Graham's review of Feilden Fowles' Food Production Campus for Charlie Bigham's is in the June issue of Architecture Today. Set in an abandoned quarry, not far from our office in Wells, the building breaks the mould of the typical shed with a bold response to its post-industrial surroundings.
On April 28th architecture critic Owen Hatherley will be leading a walking tour of Poundbury, the Prince of Wales' model extension to the Dorset town of Dorchester. Following the tour Graham will be taking part in a panel discussion in the Brownsword Hall. I'll be trying to get past the issue of style to explore whether it is a real model for sustainable development. Tickets are available from the Architecture Foundation here.

Bloomsbury House on AJ Retrofit Shortlist
Our recently completed retrofit and restoration of an 1820’s Listed Georgian townhouse in Bloomsbury has made it to the shortlist for the AJ Retrofit Awards, ‘Listed Building less than £5million’ category.
We are pleased that the recently published RIBA book 'Renovations: an inspirational design primer' by Richard Wilcox, includes our 80% house completed in 2010.
The house is living up to its name year in year out, requiring even less energy than we predicted. For those who are interested it uses around 70 kWhr/m2 annually (primary energy excluding the PV), well below the passivhaus target we were aiming at during its design!
New Architects 3
We are delighted to be included in New Architects 3, a book commissioned by the Architecture Foundation to celebrate the work of the most interesting architectural practices established in the last 10 years. The book is published by Merrell and was launched at an event at the Barbican this week.

Work Started on Timber Frame House
Work started on site this week on a new timber frame house on a beautiful sloping site in Devon. The house is being built to Passivhaus standard for a young family who work from home, so the house provides a series of living, playing and working spaces over 3 stories.
RIBA Stephen Lawrence Award Shortlist
Very pleased to announce that the Dundon Passivhaus has been short-listed for the RIBA Stephen Lawrence prize, an annual award set up in memory of the teenager who was setting out on the road to becoming an architect when he was murdered in 1993. The prize rewards the best examples of projects that have a construction budget of less than £1 million.
After lengthy negotiations with the local planning authority, we are delighted that secondary glazing has been permitted for a grade II listed building project in Bloomsbury.
This will allow this deep retrofit of a Georgian townhouse to be completed on site later this year, and will mean that the space heating requirement of the house will be within passivhaus retrofit design standards.
The photo realistic view alongside indicates how subtle we expect the secondary glazing to be.
RIBA National Award
The Dundon Passivhaus has won an RIBA National Award! You can see all 37 winners on the RIBA's website here.

High Ham House Nearing Completion
The scaffolding has come down on our latest project in Somerset, a house in the hill-top village of High Ham. By enlarging some openings and replacing the windows with single pane sliding doors the connection between the house and the landscape has been transformed. The house now enjoys magnificent views across the Somerset Levels.
We are delighted to announce that our retrofit and extension project to a house in Kentish town has been granted planning permission. As well as being underpinned by a fabric first low energy approach, there is a strong ecological bent to this project. This ambitious project includes internal wall insulation throughout and a modest extension to the rear that transforms the internal planning at ground floor.

Planning granted at Walter's Way
Planning permission was granted this week for retrofit and extension of a house designed by Walter Segal - our second in 2 months! The two storey house in Walter's Way, Honor Oak Park will be extended and re-organised internally to simplify circulation and make better use of space. Externally the house will be insulated and overclad with new horizontal timber boards, spaced to leave the vertical battens visible behind to preserve the module of the original Segal cladding system.
Rob will be leading a Masterclass on Whole-house Retrofit on 3rd October with Russell Smith of Parity Projects at the CoRE Conference and Demonstrator Centre in Stoke-on-Trent. For tickets & availability please visit the CoRE Events page.
Passivhaus Trust Masterclass
Robert will be leading a workshop on 24th September with Bill Butcher of Green Building Store for the Passivhaus Trust entitled Masterclass in Retrofit. The event will be held at the Saint Gobain Innovation Centre in central London. Places are still available - see thePassivhaus Trust website for details.
Planning granted at Segal Close
We received planning permission this week for an extension to a house designed by Walter Segal in Honor Oak Park. The proposals include retrofitting the existing single storey house with external insulation, a new lounge-dining space and external terrace. The house is part of a development of 7 houses in Segal Close built in the early 1980s by a group of self-builders on land sold to them by Lewisham Council. Walter Segal's approach aimed to simplify the methods of building using standard, off-the-shelf components so that it could be undertaken by anyone. His work is a continuing inspiration to self-builders. We are currently working on extensions to two other Segal houses nearby. The house at Segal Close is currently for sale with The Modern House.
Venice Biennale 2014
In June Graham submitted an exhibition proposal for the British pavilion at the 14th International Architecture Venice Biennale. The title of the 2014 Biennale is “Fundamentals” and overall Director Rem Koolhaas has called on national pavilions to respond to the theme “Absorbing Modernity: 1914-2014”. The competition to curate the British pavilion is being run by the British Council. Submitted in collaboration with Rob Gregory , Programme Manager at the Bristol Architecture Centre, our proposal entitled “Landscapes of Modernity” was to explore the character and presence of modernity in rural, suburban and urban contexts by charting changing attitudes and architectural responses to landscape in the period 1914-2014. Ours was one of 4 proposals short-listed. We attended an interview last week but were not successful. The winners are a team comprising FAT Architecture, Crimson Architectural Historians and Owen Hatherley. We greatly enjoyed researching the proposal and Graham will be exploring the subject of landscape and rural architecture further through his blog.
Eric Parry Monograph
Five of Graham’s detail drawings feature in Eric Parry Architects - Volume 3, the monograph series on the work of Eric Parry’s officepublished this week by Artifice Books. Four of the drawings were specially commissioned for the book. We are great admirers of Parry’s work, particularly the way materials are brought together through meticulous detailing in a way that is highly inventive but also part of a lineage of historic architectural forms and cultural associations.
RIBA CPD Seminars
Throughout 2013 Robert will be presenting a seminar with Frances Bradshaw of Anne Thorne Architects as part of the RIBA’s Core CPD programme. Entitled Climate: Building physics and retrofit design, the seminar will be held in 13 different venues across England and Wales. Places can be booked either through the regional RIBA offices or online here.
