Ian Slater Architectural Design, established in 1983, offers diverse and contemporary solutions for new houses, as well as conversions, additions and adaptations.

An award-winning 21st Century addition to a 16th Century Listed building.
(See Awards below.)

The practice places an emphasis on good design over big design and has a portfolio that demonstrates a thorough understanding of all that is required to take a building from concept to completion. From first sketch designs to detailed working drawings, procurement of materials and components, through to management of the construction process, everything is implemented with creative insight and design sensitivity.

Ian is a longstanding member of the Chartered Institute of Architectural Technologists (MCIAT) and has gained a reputation for guiding schemes through planning stages successfully, occasionally winning awards for innovation in the process, including for projects requiring special heritage, environmental and sustainable considerations.

Ian also has a very long association with small scale new home property development, often taking a slightly more radical approach to design than the usual, the results of which can be viewed on this site.

The award winning Dutch barn conversion by Ian Slater

Ian Slater's award winning redesign of the Dutch Barn at Kingsey.

Ian's innovative transformation of an imposing local farm building into a stunning contemporary home was awarded 'Best Conversion' in the 2018 AVDC Design Awards. The awards celebrate projects which make an outstanding design contribution to the Vale's built environment.

Taking full advantage of fantastic south facing, panoramic views across the Buckinghamshire and Oxfordshire countryside, the interior features a completely open-plan ground floor living area with an almost entirely glazed end, and a master bedroom above under the unusual barrel vaulted ceiling.

AVDC Design Awards 2017

Ian Slater's innovative transformation of an important 16th Century building in Haddenham has been recognised with a Highly Commended at the 2017 AVDC Design Awards.

Ian Slater's award winning transformation of The Dove House restores the individuality of the buildings with bold, contemporary solutions.

This is the fifth time Ian's work has been recognised by the Awards, which were established to celebrate projects that make an outstanding contribution to the design quality of the built environment in the district.

The Dove House is comprised of several buildings: a 16th-17th century brick and half-timbered house, a 17th century circular stone dovecote and an 18th century thatched and boarded barn - all listed in their own right. However, previous unsympathetic extensions and alterations had confused the reading of these significant and important buildings.

Ian's brief was to find bold solutions to not only restore and enhance the individuality of each building but to introduce a contemporary edge, bring more light into the interior and improve connection of the living areas to the garden.

In their comments, the judges drew particular attention to 'the brave use of a glass and oak tread staircase that works successfully in the confined space, cleverly drawing the eye toward the medieval half-timber framework.'

'Bold solutions require brave clients who have the foresight and desire to invest time, energy and, not least, money to fulfil their aspirations,' Ian acknowledges. 'Now that the work is complete our clients look forward to their home and gardens maturing in the way they had envisaged and we had designed.'

AVDC Design Awards 2011

Ian Slater's creative underground office design at Egerton House on the Chilton Estate was recognised with a Highly Commended by the 2011 AVDC Design Awards jury.

Ian Slater's award winning underground office building blends sympathetically with its surroundings.

The building was one of nine shortlisted top architectural projects, including Waddesdon Estate's Rothschild Foundation Archive Building and the Silverstone Wing at the renowned motor racing venue. Ian's concept for the Aubrey Fletcher Estate was described as: "A clever solution to the integration of new office accommodation into a sensitive rural landscape, preserving the character and views of the existing converted barns."

Ian, who was brought up and still lives locally, said at the time: "I'm delighted to be in such prestigious company. There was exceptional competition for the honours this year and I'm very pleased our innovative solution for blending such large office accommodation so well with its surroundings caught the judge's eye."



Ian Slater's work has featured in a number of publications including Ideal Home Magazine.
