Timber Case Studies

CASE STUDY 01 – Air Dried Oak Cladding

Whithurst Park Cottage, West Sussex

Designed by James Gorst Architects for a private client, this concrete and steel structure is clad with air dried English Oak ina simple 22 x 100mm square edge section, planed and laid vertically, board on board.

The cladding is untreated and left to weather naturally. Single fix to battens with austenitic stainless steel screws.

During the specification process the use of fresh sawn Oak was considered due to lower cost but the risk of distortion was considered too great and air dried material was selected instead.


CASE STUDY 02 – Fresh Sawn Western Red Cedar Cladding

Chestnut Pole Cottage, West Sussex

This is an unconventional self build project using local materials and traditional building methods.

A heavy Sweet Chestnut pole construction is based around a series of A-frames. All the timber has been sourced locally from the Cowdray Estate in West Sussex by Chris Wall-Palmer , the building owner (and charcoal maker – Didling Charcoal), with colleague Ben Law.

The shingles were cut on site from the homegrown Western Red Cedar. Each one a 300 x 100mm tapered tile (section 12/2mm). Sap is excluded and the ridge shingles are 150mm laid on end over a waterproof membrane.

The roof area is 130m2 at a pitch of 43 degrees. In order to shed water properly when using shingles the roof pitch must be between 42 and 45 degrees.

With a 100mm cover on each shingle 100 no. are required for every square metre.


CASE STUDY03 – Fresh Sawn Oak Cladding

Midhurst Cottage, West Sussex

A heavy Oak frame construction designed and Built by Tim Boxley of Downland Workshops for a private client during 2008/9 using Fresh Sawn Oak feather edge for exterior cladding.

The French Oak was cut into 25/5mm x 200mm feather section with boards approximately 3.0m long. Minor sap allowed.

Affixed with austenitic annular stainless steel nails. A single face fix to softwood battens providing tight weather resistant fit.

A beautiful honey colour when first sawn, Oak will weather down to a silver grey in time (12-24 months). Tannins will wash out during that weathering period and it is essential to use stainless fixings to avoid permanent iron stains and metal corrosion.


CASE STUDY 04 – Fresh Sawn Western Red Cedar Cladding

Orchard Way, West Sussex

A compact development of four houses with traditional Sussex facades of brick faced ground floor and timber clad first floor by Hugo Sturt of Old Rock Ltd.

Sussex grown Western Red Cedar was fresh sawn into a 25/10 x 200mm featheredge boards with minimal sap allowance, fixed to Cedar battens and laid with a 35mm overlap. Carefully detailed with rebated corner posts and diagonally ended boards to allow tight fitting.

Whilst featheredge is a traditional profile, the attention to detail has produced a clean contemporary finish. Pictured here a year after completion the cedar is weathering down to a silver grey.

The care taken in fitting and sap exclusion indicates that the cedar will achieve a durability class of 4 over its lifetime.
