There were no rafters or principal ribs for strengthening the roof besides the the common wrought-iron sash-bar… This caused some anxiety, for when the ironwork was put up, before it was glazed, the slightest wind put the whole of it in motion from the base to the summit… As soon as the glass was put in ,however, it was found to become perfectly firm and strong, nor did the slightest accident, from any cause, happen to it from the time it was completed in 1827, till ,on the death of Mrs. Beaumout , in 1832, it was sold by auction and taken down.

ACCORDING to Loudon, pieces from Bretton Hall conservatory were used on various patchwork green houses throughout the country. It is not clear what role Loudon had in this grand curvilinear design. In his 1853 the book of the Garden, the master gardener at the Dalkeith estate in Edinburgh, Charles McIntosh, says that the Bretton Hall Conservatory, says that the Bretton Hall conservatory was designed and erected by the Baileys. It is entirely possible that over an eleven-year period, which began with Loudon’s invention of the fires bar, they had developed a design build confidence of their own. A large model of Mrs Beaumont’s short-lived conservatory made its way much later to Frogmore Grardens, where it was presented to the Princess Royal by D&E Bailey, W&D’s successors, who were installing the new heating equipment there. It was their intention that it should be converted into a Wardian case for the Princess. BESIDES the curvilinear conservatory that they partially built for the Horticultural Society as Chiswick, D&E Bailey constructed the Pantheon Bazaar Conservatory and Aviary in Oxford Street, London, in 1834. This led from a Great Marlborough Street entrance into the Pantheon Bazaar designed by Sydney Smirke, on the site of the old Pantheon (now occupied by Marks &Spencer Ltd). Inside the conservatory were tropical birds and fish in bowls, along with papier-mache ornaments and sculpture. The Baileys most probably also built the triple-domed conservatory at Dallam Tower, Milnthorpe, Kendal, in the Lake District, and the delightful Palm House at Bicton Gardens, near Budleigh Salterton, in Devon, both of which still stand.
The date of the Bicton Gardens Palm House is questionable. Nikolaus Pevsnere considers that it was built between 1820 and 1825. however, Loudon made a trip to Lord Rolle’s Bicton estate just before his death in 1843 and makes no mention of the curvilinear construction in an extensive description in The Gardener’s Magazine. This might have been an oversight caused by professional envy, as Stephan Koppelkamm claims the Palm House is represented on a 1838 map. Whatever the date, the Palm House is a late and beautiful descendant of Loudon’s early designs. The detail of the elegant ironwork is reminiscent of other Bailey constructions, for example, that in the Loddiges’s Camellia House at Hackney or the Vinery at Langport. This unique desigh, which halves the number of glasing bars at

除了普通的熟铁框架，再没有横椽和拱梁来加固屋顶。这招致了一些忧虑和不安，因为，当铁质构件建立起来，在没有安装玻璃之前，任何一阵哪怕是很小的风都会使整个铁框架从底到顶地晃动起来。然而，一旦玻璃被装上以后，整个框架就会让人感觉到异常的稳定和坚固，自从1827年建成到BEAUMOUT 女士临终时，无论是从任何方面都没有发生过哪怕是一起极轻微的事故。1832年这个建筑被拍卖并且被拆除。
据loudon说，拆下来的bretton hall 温室的部件被应用到全国范围内的各类组合式温室建筑上。在这个雄伟的曲线形建筑的设计上，LOUDON 究竟扮演了甚么角色，我们不得而知。在他1853年的园艺书中，和爱丁堡的Dalkeith 庄园的园艺大师Charles McIntosh说，Bretton Hall温室是由baileys设计和建造的。这也完全有可能，因为自从开始使用LOUDON 发明的框架，已经是11年了，BAILEYS 已经树立起了他们自己从事建筑设计的信心。像BEAUMONT 女士所拥有的那种大型的“短寿”温室是许多年以后在FROGMORE gardens 中又重现的，是由W&D BAILEY的后嗣D&E Bailey献给长公主的，他们在那里安装着新型加热装置，并且想把这个暖房改建成长公主的沃德箱。除了参与了在CHISWICK 的Horticultural Society 的曲线形温室的部分建设工作以外，（这里as应为at)，1834年，D&E Bailey在伦敦的牛津大街又建造了Pantheon Bazaar温室和大型鸟舍，这套从Great Marlborough 大街的一个入口进入到Pantheon Bazaar的建筑是由Sydney Smirke在Pantheon的旧址（现在被Marks &Spencer 有限公司占用）上设计的。温室里面，在纸类饰品和雕塑之间，生活着热带鸟类和游曵在容器中的鱼类。BAILEYS 很可能还在位于Lake District的Kendal-Milnthorpe-Dallam Tower（这里是地名，类似于X省X县X乡） 建造了三拱顶植物暖房，和在位于DEVON，且靠近BUDLEIGH SALTERTON的BICTON GARDENS 内建造了令人心旷神怡的温室，这两个建筑至今尚存。
BICTON GARDENS 的温室的建造日期无法确定，Nikolaus Pevsnere推测它可能建于1820-1825年之间。不管怎样LOUDON 在1843年，他临死之前到Lord Rolle’s Bicton 的庄园去了一趟，但是，在 园艺家 杂志的详尽记述中，他却没有提及这座建筑。
或许是出于行业性的妒忌，被LOUDON 而故意忽略。因为Stephan Koppelkamm声称，在1838年的地图中就已经标有了这座温室。不管什么时候，这座温室的确是从LOUDON的早期设计中演变而来的
美丽新的造型。这些宏伟的铁制构件部分使人回想起BAILEYS 的其它一些建筑。例如，在位于HACKNEY 的LODDIGES内的山茶花房 或在LANGPOR的葡萄园。这种独一无二的设计去除了建筑中一半的玻璃横椽。在
