How the Ancient High House in Stafford Was Built

The Ancient High House in Stafford is widely recognized as the largest surviving timber-framed Tudor townhouse in England. Constructed around 1595 for the affluent local merchant Richard Dorrington, the building exemplifies classic Elizabethan engineering and architectural ambition. This article examines the structural methods, materials, and specialized craftsmanship that allowed this remarkable four-storey landmark to be erected and endure for centuries.

Timber Frame and Sourcing

The structural framework of the Ancient High House was crafted almost entirely from English oak. During the late 16th century, local Staffordshire woodlands provided dense, mature oak trees capable of bearing the immense structural loads required for a multi-storey civic building. Green oak was predominantly used because it was easier to shape with hand tools, gradually hardening as it dried in place to create a rigid, highly durable frame.

The Jettying Technique

A defining architectural feature of the building is its jettied construction, where upper floors project outwards beyond the dimensions of the floor below. The house rises four storeys, with each successive level cantilevering over the street.

To achieve this:

  • Heavy horizontal beams (bressummers) were laid across projecting floor joists.
  • Vertical wall posts of the higher storey rested on these bressummers, shifting weight downward through the frame.
  • The technique maximized interior square footage on the upper floors while preserving pedestrian and cart traffic space along Greengate Street below.
  • The cantilevers protected the lower timber joints and wattle-and-daub panels from direct rainfall.

Prefabrication and Joinery

Like most major Elizabethan timber structures, the Ancient High House was prefabricated off-site in a framing yard. Master carpenters cut, measured, and dry-fitted the timbers flat on the ground before moving them to the city center.

To assemble the structure:

  • Mortise and Tenon Joints: Timbers were connected using precision-cut mortise and tenon joints rather than metal nails.
  • Wooden Pegs (Trenails): Once the joints were interlocked, holes were bored through them, and dried oak pegs were hammered in to lock the connection permanently.
  • Carpenter's Marks: Numbered notches were gouged into the wood near joints so builders could quickly match and erect the corresponding pieces on-site.

Infill and Wall Composition

Once the oak skeleton was anchored atop low stone foundation footings, the open panels between the timber studs were filled using traditional wattle and daub.

Wooden staves were wedged vertically into the frame, and flexible hazel or oak branches (wattles) were woven horizontally between them to form a sturdy mesh. Builders then applied a thick daub composed of wet clay, soil, straw, and animal dung to both sides. Once dry, the panels were coated with a protective lime wash, producing the distinctive black-and-white contrast typical of vernacular Tudor architecture.

Roof and Interior Chimneys

The roof was constructed using a steeply pitched timber truss system capable of shedding rainwater and supporting heavy Staffordshire clay tiles. Heavy load-bearing brick chimney stacks were integrated into the structure from the ground up, providing both structural stability to the timber frame and functioning hearths for heating and cooking on multiple floors without posing an immediate fire hazard to the wooden walls.
