The type of dwelling Burley Griffin envisaged as the model house for the new bush suburb of Castlecrag was based on a new technological innovation in building called Knitlock Construction, or as Griffin more grandly termed it, Segmental Architecture. The American had pioneered and co-patented (with D C Jenkins) the Knitlock system in 1917 whilst working on the Canberra Capital Project. The Knitlock technique was to become the archetype for all of WBG’s subsequent domestic architecture.

Griffin’s Segmental Architecture was a quantum step forward from previous building technologies used in Australia (eg, Mack Slab) [M Lewis, ‘Knitlock’, www.mileslewis.net]. Intended by Walter for use on workmen’s cottages in Canberra (before the disintegration of his Capital City dream), the technique heralded a variety of radical advances in construction. With a simplicity and economy of design, the Segmental Architecture method constructed walls from ‘segments’ of precast reinforced concrete which were easier and quicker to construct than other methods (Griffin was one of the early developers of prefabrication). The Knitlock bricks, machine-manufactured on the southern side of the ‘Crag estate in a shed set up on the corner of The Redoubt and The Rampart, were light yet compact and sturdy. The bricks were reinforced with a dual ‘vertebrae’ structure which forms a concrete skeleton. The sections were easy to transport, easy to assemble as walls and cheap to make [W B Griffin, Australian Home Builder, No 1 (August 1922)].

Added to this, another major advantage of Knitlock was the convenience. The bricks did not require cutting, bedding or plastering, working instead on an interlocking join to connect them together (the prefab concept). A further advance was that Knitlock technology allowed for greater diversity in shapes for features of the house [‘Landmarks: Urban Life’ (National Museum of Australia) www.nma.gov.au/.].The beauty of Burley Griffin’s domestic construction using this system was that it could produce buildings that were simply designed and quickly constructed – non-standard workers’ cottages which were affordably priced. Affordability was an important requirement for the Griffins, the capacity of workers to afford their own home squared with their own espoused egalitarian and democratic principles.

The prototype for all of the Knitlock houses built in the Castlecrag and Haven Estates by WBG was ‘Pholiota’, the Griffin’s own small, ultra-modest home set among red gums and bush in Heidelberg, Victoria, before they moved to Castlecrag. This most basic, pared to the bone, single-roomed, utilitarian house, provided an example that any layman self-builder could follow. As proof of this, ‘Pholiota’ was erected in double-quick time apparently by Walter and Marion themselves with the assistance of a local chicken farmer!

Fishwick

Burley Griffin’s finest architectural achievement in Castlecrag is probably Fishwick House (№ 15 The Citadel). Because of his client’s requirements (large budget, expansive house), Walter deviated from his usual prescription of a small-scale “no frills”, minimalist, unembellished cottage. Fishwick House is a more grand house, emphasising horizontal eaves and porticos. At the sides and rear of the house judicious placement of large picture windows and glass doors permits cascades of filtered sunlight to enter the living room from varying angles [www.griffinsociety.org/]. This aspect of Fishwick House echoes the interior courtyard of Stanley Salter House in Toorak, Melbourne, which some architectural specialists rate as WBG’s best residential building [eg, James Birrell, cited in ‘Stanley Salter House’, De de ce, www.dedece.com]. Griffin’s use of open-plan interiors demonstrates the architect’s belief that the house shouldn’t be a haven for withdrawal from the outside world, but rather “a place for reflection and engagement with the surrounding environment” [ibid.]. WGB defied the conventions of the day for home design, putting “living rooms at the rear and opening to the landscape and views, and had utility rooms such as kitchens and bathrooms fronting the street” [M Petrykowski, ‘Architecture’, www.griffinsociety.org/].

Duncan

The attitudes of pioneering residents of the Castlecrag Estate to the Griffin signature home were mixed. Some like Frank and Anice Duncan were delighted with the nature-centredness and functionality of Walter’s dwellings. The Duncans lived in no less than four of the houses over the years. The fourth one, the Duncan House at 8 The Barbette, specially commission by them, was the last Griffin-built home in Castlecrag.

However other residents were less sanguine about the houses – some with very good reason. The flat roofs on the early Knitlock constructed homes had a tendency to leak. Ellen Mower, first occupant of № 12 The Rampart (Mower House), was plagued by leaking roofs and eventually Griffin had to buy back the house from the owner [www.griffinsociety.org]. Mower House, incidentally, was the last home Marion lived in after her return from India after Walter’s death in 1937. Similarly, Mrs A E Creswick, who commissioned the small house built at 4 The Barbette (Creswick House), was similarly dissatisfied with the standard of her home and the Griffins had to re-purchase this dwelling as well [Castlecrag Progress Association, www.castlecrag.com.au/].

Dr Edward Rivett, who converted the King O’Malley House in Sortie Porte into Castlecrag’s first hospital, also commissioned the Griffin-designed 148 Edinburgh Road, however he altered the original plans to add a pitched tile roof and interior walls which were brick rendered. Griffin through GSDA, his company, sued Rivett for breach of Covenant and a lengthy legal battled ensued which was eventually won by Dr Rivett. Other potential buyers also had problems with the Covenants imposed by WBG and many turned away from Castlecrag, opting instead for the railway-serviced suburbs on the Upper North Shore which didn’t have restrictions on the size or type of house or on how or whether you landscape your property [‘Castlecrag’,www.sydneyforeveryone.com.au/].Because of the restrictions and other contentious issues surrounding the construction of GSDA dwellings in the estate, banks became less willing to approve loans on Griffin houses. The onset of the Depression strangled the economy which affected development everywhere in Sydney, but subdivisions that were less popular like Castlecrag suffered its effects hardest [ibid.]. Castlecrag had to await the postwar building boom to achieve significant inroads in development.

Another factor holding back Castlecrag’s development at this time was getting to and from the Middle Harbour promontory! In the 1920s the Middle Harbour promontory was severely hamstrung relative to transportation options. Before the Sydney Harbour Bridge was constructed it was a very long haul by road to Castlecrag (cars in the 1920s were in any case still fairly scarce), and the eastern part of the Northern suburbs lacked a main arterial road (Eastern Valley Way was a post-war development). In addition, trams on the north side of the harbour did not go as far as Castlecrag in the interwar period [G Wotherspoon, ‘Ferries’ (2008), www.dictionaryofsydney.org/]. A story told by the son of Edward Haughton, Burley Griffin’s Melbourne estate agent and valuer, is instructive. The father and 10-year-old son came to Sydney to assist WBG in promoting the Castlecrag Estate. Haughton’s son later recalled how difficult it was and how long it took to reach Castlecrag (from the city: walk/ferry/elevator/tram/walk) [recollected for M Walker, et al, ‘forming the Greater Sydney Development Association’, www.teachingheritage.nsw.edu.au/].

Burley Griffin’s attitude towards building materials was every bit as rigidly purist as his attitude was to how the finished product should look. He championed the use of concrete and stone (particularly local Castlecrag sandstone which blended in with the natural setting). Conversely, he railed against the popularity of the standard building materials of the day, brick and tile, which he rejected.

Marion was equally purist in her aesthetic preferences. Bernard Hesling, a Castlecrag resident in the Thirties recalled Mahoney “scrambling the hills like a billy goat” and pointing southwards to the predominance of red roofs and lack of trees in Northbridge, exclaiming loudly in her thick Midwest American accent “It’s hoorabul, hoorabul! Walter and I wanna keep the Crag voigin bush!” [‘Willoughby Walking Tours’ (Willoughby City Council), www.walks.willoughby.nsw.gov.au/].

The proportion of Burley Griffin designs converted into houses by GSDA over a 14 year period was quite low. Only 15 built in the Castlecrag and Haven Estates (none built north of Edinburgh Road, the area known as the Wireless or Sunnyside Estate) with about four or five other houses designed by one of WBG’s acolytes but approved by him. In what is somewhat of a trademark feature of Griffin’s oeuvre, many houses proceeded no further than the drawing board. WBG designed in the vicinity of 35 or so others for the ‘Crag that were not carried through to completion [‘The Idealists: creating Castlecrag’, ABC RN, Hindsight, 8 July 2012]. There was a host of reasons for this as outlined above, but sometimes sheer bad luck played its part in Griffin’s fortunes. Global developments had a tendency to intervene to stymie his noble intentions. Just as his vision for a physical landscape in Canberra worthy of the capital city of “a nation of ‘bold democrats” ran smack into the war effort of WWI which redirected valuable Australian resources away from WBG’s project, the development of Griffin’s estate in Castlecrag had its momentum undercut by the crippling effects of the Great Depression [‘Creating a new nation’s capital: The Griffins’ vision for Canberra’, (National Archives) www.naa.gov.au/].

When Walter’s private and GSDA commissions started to dry up, he increasingly took on industrial building design work. By the mid-1930s, frustrated by the lack of work in Castlecrag, Burley Griffin took up an invitation to design buildings for the University of Lucknow. The move to India, only intended to be a temporary one, served to re-energise Griffin’s architectural ambitions, allowing him to explore the fusion of ancient Eastern architecture with Western modernism. WBG engrossed himself in many new Indian projects but unfortunately, in a familiar story, the local colonial bureaucracy obstructed the realisation of most of the projects [G Sherington, ‘India’, W B Griffin Society, www.griffinsociety.org/].

‘Camelot’

EM Nicholls: Keeper of the Griffin flame
After the Griffins left Australia, his protege-cum-associate Eric Milton Nicholls took over the running of GSDA in Sydney and became the “keeper of the flame” for Griffin’s architectural vision. Nicholls soon started to design houses in Castlecrag in his own right. The pick of Nicholls’ work are probably Camelot (formerly called Pangloss) at № 3 The Bastion, and the all-white Moriaty House at № 215 Edinburgh Road. Camelot, with castle features including a Martello tower, is distinctively Nicholls’, but its circular stone design shows the clear influence of WGB’s earlier design for the Symington Parapet project [‘Castlecrag’, (Willoughby Dist. Hist. Soc.), www.willoughbydhs.org.au/].

Nicholls was a prominent architect in the Willoughby area, designing many domestic and public buildings in Sydney and Melbourne. An Anthroposophist like the Griffins, he was involved in the establishment of Steiner Glenaeon Schools in Middle Cove and Pymble [‘Eric Nicholls’, (Willoughby City Council), www.willoughby.nsw.gov.au]. Burley Griffin’s influence lives on in Castlecrag and elsewhere … The Griffin (8 Rockley Street), designed by Alex Popov in 1990, won the Robin Boyd Award (Australia’s leading residential architecture prize) – the building was described by the judges as “a reverent tribute to Griffin” [WDHS, op.cit (‘Castlecrag’).].

FN: The WBG sales pitchThe sales brochure of the Greater Sydney company (the Griffin’s firm) reads: “Castlecrag architecture has struck a distinct bold note in Australia. In place of the high peaked tile roofs … the handsome landscape style, with the stone walls and flat roofs, has been introduced in harmony with the great amphi-theatre of stone and forest”.
