A situation to test your plan against
A house with timber and other natural surfaces gains character through use and ageing. Do not choose only from a new sample. Discuss how colour variation, touch and outdoor exposure will form part of the design.
What this work involves
Assess structural function, deterioration and connections. Coordinate exposed and concealed elements with the structural design.
- Member layout and connections
- Exposed or concealed finish
- Connections to the existing building
Coordinate exposed timber elements with their structural role explicitly.
What the drawing needs to explain
Detail the lower edge and the junction with another material. Show where water can drain and how an element can be replaced without opening the entire finish.
Decide this before construction
Select the material early enough to design edges and fixings around it. Review a sample in its intended location before placing the full order.
Compare the complete intervention
Compare purchase and recurring maintenance costs. Ask about preparation, fixings and access; the material price per square metre alone gives insufficient guidance.
How to review the result
Assess variation against the agreed sample and product information. Distinguish natural differences from damage or an incorrectly executed junction.
Cost factors for this service
Costs depend on spans, timber selection, repairs and installation. Ask for the scope and selected specification to be described separately.
Bring this to the discussion
Photographs of the existing situation, available drawings and your requirements for timber structures & joists. Identify the elements that should remain.
Questions about the work
What should I discuss before arranging timber structures & joists?
An exposed beam needs different finishing agreements from a concealed structure. Record this before materials are ordered.
Is timber weathering always a defect?
No, ageing can be part of the material choice. Agree the expected appearance and maintenance beforehand; moisture problems, damage and incorrect detailing require a different assessment.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
