1) Project planning- The Key element schedule should be agreed in advance so as to allow the timber frame manufacturers to plan design along with the fabrication process,with on time deliveries and site erection being efficient.


The reduction in downtime for the manufacturer helps to minimize costs to all parties, it also reduces uncertainty, and allows the build schedule  to be kept to. To plan an effective build program, the timber frame manufacturer (who generally provides a full erection service) will need to receive the full detailed design information in good time. The timber frame erector will need to receive a clear and concise brief for site management. A realistic build program should be agreed by all parties. The timber frame manufacturer will also require a full brief on contractual responsibilities including health and safety.

The Key health and safety issues and requirements are:

  • Construction (Design and Management)Regulations
  • Risk assessments
  • Method statements
  • Full scaffolding
  • Fall prevention and arrest methodologies
  • Control of lifting operations
  • Any necessary training, and training records
  • Site security
  • Manual handling


2). Preliminary design stage.

Timber frame used  in panel construction is a versatile and very capable building system. It can be used with various types of cladding (e.g. brick, stone, render, timber, plastic). However, the integration of materials, such as steel and concrete, into floor and wall elements of timber frame construction requires special consideration due to the movement of timber with changes in moisture content. On-site fabrication of specialized panels (e.g. for curved  or arched walls), or use of non-panelized components, is possible  without affecting the building method or performance as a whole.

While timber frame is a versatile method of construction, certain building features –  there are some elements that need other elements ,for example, brickwork at upper set-back elevations and cantilevered balconies – require special design attention and detail. Long floor spans can be achieved by using engineered wood products or by designing the floor deck as a stressed skin panel however these will require specialist design  elements and construction techniques. Platform timber frame is ideally suited to cellular layouts with load bearing partitioning in vertical alignment through the building.

3).Stategic trade planning:

The trades responsible for installing or fixing the following building components should be fully briefed on the requirements for timber frame design and construction:

  1. Thermal and acoustic insulation ( walls and ceilings)
  2. Vapor control layers
  3. Wall linings ( and finishings)
  4. Fire stops and cavity barriers
  5. Services (including drilling and notching of joists and studs)
  6. Acoustic flooring
  7. Provision for differential settlement (see base variants)
  8. Weatherproofing (ventilation, weep holes etc)
  9. Wall ties (inc'l positioning and spacing)
  10. Battens and counter battens for cladding and paneling
  11. Cladding interfaces with the timber frame structure and particular care should be taken in providing for differential movement as the timber frame dries out.

Measures include:

  1. Allowing adequate shrinkage gaps below windows and other projections over the outer leaf, including the roof elements.
  2. Using the correct type of compressible spacers and fillers. Limits on compressibility should be noted for these materials.
  3. Correct installation of services
  4. Providing for differential movement at openings for windows, doors, services, lift shafts, and stairwells, and at roof soffits, junctions between cladding types, etc
  5. Using flexible wall ties in buildings above three storey's.

Major steps A-Z  in building a timber framed home:


  1. Have a suitable land plot for construction and confirm planning allowance.
  2. Have design concept agreed with design or construction company ( 2D and 3D project concept).
  3. Have planning permission application and approval to build.
  4. Confirm availability and connection to local services ( water electricity and waste).
  5. Have a the project agreed with planning the shedule for building.
  6. Have all out side trade elements agreed and included into the build shedule.
  7. Clear all health and safety issues.
  8. Engage a project manager to oversee the build schedule ( can be the construction company)
  9. Confirm budget for the whole process is in place ( for stage payments need to be agreed in advance at time of contract signing).
  10. Commence shedule:
