Understanding Timber Frame Construction
Timber frame construction is an age-old practice with roots dating back to Neolithic times. This method involves constructing a structural framework using heavy timbers joined together with various joints and bracing. Traditional timber framing techniques include half-timbering, post and lintel, and box framing. For larger modern timber frame structures, an aisled frame with rows of interior posts bearing more structural load than the exterior wall posts may be employed. In most timber frame constructions, these techniques are adapted to create efficient and durable modern timber frame buildings.
Erecting a timber frame building follows a simple procedure. It involves:
- Using floor-to-ceiling height panels to form each storey, with the floor deck serving as the platform for erecting the subsequent floor.
- Constructing the timber frame panels and roof structure from trussed rafters.
- Enabling the rapid creation of a weather-proof building within just 2-3 weeks.
Contemporary timber frame buildings undergo careful design, often incorporating structural steelwork to tackle intricate engineering challenges. The structural integrity of the building is maintained through the cohesive engineering of walls, floors, and roofs. Systems like structural insulated panels (SIPs) are used to optimize performance.
Currently, about a quarter of new constructions in the UK utilize timber frame construction. The timber used is procured from environmentally sustainable British and European forests, signifying a substantial market acceptance. This marks the significant role timber frame construction plays in advocating for sustainable building methods.

Choosing the Right Timber Frame Supplier
Selecting an appropriate timber frame supplier critically influences the success of your project. It is important to consider the supplier’s experience, certifications, and the range of services provided. The services offered can range from supplying only the superstructure to providing a complete package including design, construction, and additional services.
One way to ascertain the reliability of a timber frame supplier is to check for STA Assure certification. This is a quality and standards scheme that mandates regular assessments and compliance with minimum requirements in areas such as site safety, training, and in-house quality checking, resulting in bronze, silver, or gold certification. Opting for a supplier with STA Assure certification can guarantee elevated standards of quality and dependability.
It’s vital to compare similar offerings while assessing the specifications provided by various timber frame companies. Examining past projects can provide valuable insights. For instance, the farmhouse choice by Richard and Beth Wilson who selected Fleming Homes for their kit, or the well-insulated and airtight timber frame also supplied by Fleming Homes for a house on the Scottish coast, are excellent examples of quality timber frame constructions.
Key Components of a Timber Frame Structure
Several key components make up a typical timber frame structure. These include:
- Softwood vertical studs
- Horizontal rails
- Wood-based panel sheathing
- Plasterboard lining
This construction provides stability and strength to the wall structure. The sheathing serves to provide wind resistance, contributing to the overall structural integrity of the building.
In timber frame construction, there are open panels and closed panels. Open panels are transported to the construction site with components such as flooring and roof trusses. On the other hand, closed panels come equipped with pre-installed insulation, and may also include exterior cladding and installed services. The integrated insulation in closed panels improves energy efficiency and can offer advanced options.
Installation of a vapour control layer on the ‘warm’ side of the insulation is advised to prevent condensation in a timber frame structure., while a vapour permeable membrane should be placed on the exterior side of the sheathing board. This arrangement keeps the timber frame protected from water penetration and allows water vapour to escape.
Attention must also be given to service ducting and penetrations in timber frame walls to avoid air leakage and potential condensation problems. Properly sealing these joints is essential to preserve the structural integrity and airtightness of the timber frame.
Navigating Planning Permissions and Building Regulations
Any timber frame project requires careful management of planning permissions and building regulations, ensuring adherence to both local and national standards. For instance, in the US, timber framed outbuildings, including:
- sheds
- greenhouses
- swimming pools
- cabins
are typically permitted as long as they are not located in front of the principal wall of the main building.
The process to obtain planning permission can vary in duration. For example, the Gibsons obtained planning permission for their home in a period of eight weeks. However, it’s necessary to note that the timeframe could be different depending on the local council and the specifics of the project.
It’s worth investing time and effort in understanding the planning permissions and building regulations applicable to your project. Not only will this ensure that your project is legally compliant, but it will also help avoid potential roadblocks during construction.
