The Twyning estate's history traces back to the Hancock family, long-standing landowners and lords of the manor who built their prominence through generations of agricultural stewardship. Through marriage, the property passed to the Maxwells, eventually reaching Jane Stocker (née Maxwell). Following her inheritance in 1858, Jane and her husband, Royal Navy Captain Walter B. Stocker, chose to replace the older residence with a grand new family home.

Commissioned to design the estate, the Victorian architectural firm Medland and Maberly prepared bills of quantities alongside comprehensive building specifications. Between 1859 and 1860, they produced detailed plans, elevations and ornamental sketches, together with blueprints for a matching entrance lodge that still stands at the end of the driveway. Many of these original documents remain preserved within the Gloucestershire Archives. Erected between 1859 and 1862, the manor was built using locally quarried blue lias - a fine-grained stone sourced from the Severn and Avon vales near Tewkesbury - creating a striking Victorian country house set within private acreage.

Extensive modernisation followed between 1920 and 1923, introducing upgraded drainage systems and a dedicated engine room to provide electricity to the entire estate.

After more than a century as a private family residence, the manor eventually fell into mild disrepair before transitioning into 13 separate dwellings through subdivision. This configuration comprises 12 distinct apartments inside the main building alongside the Wing House, an attached cottage formed from former servants' quarters. Garages today occupy the site of the former stables, where horses and carriages once stood.

Although subsequent conversion resulted in the loss of much intricate stonework and neo-Gothic detail, several subtle architectural features still grace the exterior. A carved stone crest uniting the Maxwell and Hancock families sits above the doorway, directly opposite the traditional Hancock crest. The front door is authentic, matching specifications found in 1859 drawings. Small fragments of original carved masonry also survive around the exterior, complemented by original cast-iron finials crowning gabled roof peaks.

Keen observers will notice that parts of the original patterned roof tiling have likewise endured. Among the surviving original features are the cast-iron rainwater hoppers, which still bear the cast date of 1859 and display decorative roses as a subtle nod to the local Battle of Tewkesbury. 

Completing the historical narrative, two stone gargoyles that once adorned the building were removed during redevelopment; today, they rest outside the primary entrance as striking reminders of the manor's original neo-Gothic grandeur.
