A 16th-century English longhouse hid serious structural problems behind its walls; The builder who restored it has turned the century-old property into his own family home.

Cadman Construction was already undertaking one of its most challenging heritage projects – restoring a Grade II listed 16th century longhouse in Suffolk. But for Stuart Cadman, managing director of Cadman Construction, the challenge had an added dimension: the century-old property would eventually become his family home. The restoration included repairing much of the original oak frame, but also creating contemporary spaces that met the needs of modern family life. At all stages there was a balancing act between preserving the historic fabric and meeting current building standards, conservation requirements and the practical realities of restoring a building more than 400 years old, states an interview with Cadman published by the Heritage and Traditional Building website. Some of the biggest challenges didn’t arise until we were working on it, Cadman mentioned in the interview. It was mentioned that at the south end of the house, the original oak frame was found to be a mix of oak and softwood. Much of the soft wood had rotted to the point where it could be safely supported. The south chimney was also identified as a hybrid construction with limited historical significance. According to the interview, the findings meant the project required a new planning application and listed building consent to allow the demolition and reconstruction of much of the southern section. The restoration was delayed approximately six months due to approval processes, the report added.

Piece by piece, holding up a 400-year-old building

The restoration team opted for a more cautious approach rather than trying to support the entire building at once. The perimeter beam of the first floor was supported in six-meter sections by a shoring system designed by a structural engineer. Each section could then be carefully checked before repairs were made. The team followed the same process on the rest of the building after successfully completing the first part. The technique reduced the risk and left the historic oak frame largely intact while its condition was assessed. For a century-old structure, it was imperative to proceed with caution. The project demonstrated that heritage restoration requires both patience and technical expertise.

Where 16th century character meets modern life

The new extensions were built to modern building standards but designed to be visually compatible with the original longhouse. The old and the new were intentionally kept different. Modern windows and construction details help distinguish the additions from the historic structure, but the design as a whole allows the additions to sit comfortably next to the historic structure. No less significant were the traditional materials. For the existing building, the choice fell on locally sourced William Blyth clay slabs and lime plaster. Lime plaster also has a functional role in historical construction. Older buildings breathe and traditional materials allow humidity to regulate itself, rather than being trapped within the building.

Collaboration and craftsmanship

The restoration required close cooperation between contractors, conservation specialists, structural engineers and local authorities. This type of collaboration is especially important for listed buildings, where even minor changes can often require a lengthy assessment and approval process. The experience also highlighted the need for patience when working with historic properties. Specialist craftsmanship remained central to the project, supported by modern techniques to maintain the character of the original structure.

Saving the past for another 400 years

For Cadman and his family, finishing the restoration is about more than just moving into a beautifully renovated home. It means helping to secure the future of a building that has existed for more than four centuries. The original structure and chimneys could date back to craftsmen working during the reign of Henry VIII, placing the property within a notable stretch of English history. The finished house is a union of two very different eras. The historic fabric is visible and respected, while the contemporary additions offer the comfort and performance expected of a modern family property. The project has also increased Cadman Construction’s confidence in heritage work, giving the company a greater understanding of the risks, processes and practical challenges involved in the restoration of listed buildings. For this century-old Suffolk longhouse, the aim was never to restore what had been lost. Keep the history of the building alive, write another chapter in it that would last centuries.Images courtesy: Heritage and Traditional Construction
