Reference excerpt

Lindlegreen Barn is a heritage-listed former Aboriginal land, farm and barn and now shed at 2509 O'Connell Road, O'Connell, Oberon Shire, New South Wales, Australia. It was designed by Thomas Hassall and built during 1827 by John Barker. It is also known as The Lindlegreen Barn and Hassall Barn. It was added to the New South Wales State Heritage Register on 24 August 2018.

History

O'Connell Region O'Connell is believed to have one of the highest concentrations of earth buildings in Australia, with some structures dating back to the early 1800s. Lindlegreen is part of the 324-hectare (800-acre) farm granted to Reverend Thomas Hassall by Governor Brisbane in June 1823. The land was in part a fulfillment of a grant made to Hassall by Governor Macquarie in 1818, but not surveyed or registered. Hassall called his farm Lampeter, or Llambeda, after the theological college in Wales where he studied. Hassall was born in Coventry, England in 1794 and travelled with his parents to Tahiti in 1796 and, subsequently, Sydney in 1798. Hassall was son of missionary Rowland Hassall, preacher and landholder in the Dundas and Parramatta areas after the arrival of the family in the colony. The Hassall family had a close association with Samuel Marsden and were involved in early itinerant ministries in the Sydney area. In May 1813 Thomas Hassall opened the first Sunday school in Australia in his father's house. This venture was so successful that Hassall senior, John Eyre, and other leading Dissenters and Methodist formed the NSW Sunday School Institution in December 1815. As Hassall's religious convictions strengthened, he decided to enter the ministry and he became the first Australian candidate for ordination. Following ordination Hassall became Marsden's curate in Parramatta and in 1822 he married Marsden's eldest daughter Anne. Hassall was appointed the first Chaplain of the Bathurst District in early 1826 which was incidentally the area where his father Rowland had conducted the first sermon. While Chaplain, Hassall lived at Lampeter Farm where he built Salem Chapel, and he preached regularly at a barn at Kelso which had opened as a church in 1825. In March 1827 Hassall was appointed to the new parish of the Cowpastures which he described as "Australia beyond Liverpool". In this parish, where he remained for the rest of his life, Hassall resided at the estate of Denbigh at Cobbitty. He appears to have kept some interest in his farm at O'Connell as in the 1828 census he is listed as having 41 employees there, which were nearly all convicts. Lampeter was one of six blocks at O'Connell Plains held by sons or sons-in-law of Rowland Hassall. Lampeter was Lot 9 and was adjacent to the present O'Connell Road from Beaconsfield Road to Mutton Falls Road. The Lindlegreen Barn was built in 1827 based on the available account book details in the Hassall family correspondence at the Mitchell Library. The details noted the payment of A£17 to John Barker for putting up a barn. Barker, a labourer, aged 30 was listed in the 1828 census in Hassall employment at Bathurst. The Hassall's had apparently been storing wheat at O'Connell Plains as early as 1822 and it is possible that the banr was used for this purpose. While there is no reference to the building materials used in this account, in a 1902 publication by Hassall's eldest son, James S. Hassall, he indirectly refers to some general aspects by noting that "some cottages (at Denbigh) had been built, not of sods, as at Bathurst, but of rammed earth". Hassall also later built a chapel, Salem Chapel, in the vicinity of the barn in 1834. This chapel survived until 1975 as part of the Anglican church group located to the west of Lindlegreen. The barn is marked on the 'Plan of 41 acres of Land to be given by Rev'd Mr T. Hassall for a Clergyman's Residence at O'Connell plains 1838'. As such, it is slightly unclear if the barn was part of a rectory here after this date. Later ownership of the property includes the following: 1920 a further subdivision of one hectare (two acres) between the road and Fish River and another of just over three hectares (seven acres) containing the house and barn with both lots being sold to Catherine Morgan, wife of Samuel Richard Morgan, storekeeper; 1951 sold by Iva Mary Morgan to Letitia Caroline Spicer, spinster of Concord; 1961 sold to John and Theresa Condon; 1961 sold to Joyce Parsons, proprietor of the O'Connell Service Centre; 1970 sold to John Reynders, stationhand of Tarana; 1981 sold to Ronal and Sylvia Farlow; 1988 sold to Robert and Alice Ashelford; and 2015 sold to Bradley Andrew Hargens. The history of the house Lindelgreen and the evolution of the building has yet to be documented. The 1838 survey plan shows the barn and the chapel, but also a number of buildings on the northern side of Beaconsfield Road close to the barn, one of which is likely the later School of Arts. Peg Savage, a local O'Connell historian, suggests in her historical notes that Lindlegreen may have been called Lampeter Cottage, however, it is also said that Hassall may have also built a second house called Lampeter close to the village near Mutton Falls Road. Oberon Council allocated a $110,000 grant from the NSW Office of Environment & Heritage towards three workshops teaching O'Connell residents how to maintain and repair earth buildings. Workshop coordinator Angus McKibbin has fond memories of playing in the state-heritage listed Lindlegreen Barn (1827) as a child, which encouraged him to kick-start the project. 'Over the last 50 years, I've watched the barn deteriorate and after discussions with the current owners, we decided to resurrect the building before it was too late', he said. The Bathurst and District branch of the National Trust of Australia (NSW) presented their monthly heritage award for July to this joint Oberon/O'Connell project aiming to restore the region's buildings.

Worked examples

Example 1 — a first encounter with Lindlegreen Barn

Start with the simplest possible case. Write down what Lindlegreen Barn claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lindlegreen Barn before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lindlegreen Barn ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lindlegreen Barn

In research: Lindlegreen Barn appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Lindlegreen Barn in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Lindlegreen Barn is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1827 establishments in Australia, Agricultural buildings and structures in New South Wales, Barns, so understanding it makes those chapters shorter.
In everyday life: Look for Lindlegreen Barn outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
