New Build House
Shown below is new build green
oak timber frame house constructed locally to us in the Tamar Valley
. This is an unusual frame because an unusually large 10in x 10in
oak dimension was specified.
Self Contained Annexe / House Extension
Shown above and right: a green oak self contained open to the
eaves extension/annexe built onto a Devon longhouse on Dartmoor
is shown here viewed from two sides to show fully how infil panels
and direct glazed units can be used together on a timber frame to
provide both efficient insulation and a fantastic light and airy
building. The front view shows seasoned oak double glazed french
doors and the side view shows the green oak porch mounted on staddlestones.

Green Oak timber framed bungalow
below is a green oak timber framed extension to a bungalow in Devon.
The picture below shows the green oak structural frame and, below
that, the extension is shown with the green oak frame surrounded
by softwood studwork on which insulation and external finish will
be fixed. This constrution method allows for the building to have
an internally visible load bearing green oak timber frame giving
character and for the timber frame to be surrounded by a highly
energy efficient 'envelope' of insulation. The method also allows
for easy fixing of doors and windows and does not require the more
complex glazing system needed if glazing is applied direct to the
green oak timber frame.
and the pictures below give a peek at the finished rooms

trusses can add character to buildings and can be made in many different
styles. Shown above is a house extension
with King Post trusses made from English Green Oak with curved struts.
We will make up an individual truss or a full roof as required.

Green Oak glass roofed pergolas, with stainless
steel laser cut braces and and external/garden fireplace and chimney
made by us from Corten steel.
The image below was the
concept drawing for a project which included a green oak timber
framed outdoor dining shelter with a glass roof and a large fireplace
with chimney. A second oak frame houses a hot tub and the open area
between the two structures has a removable fire retardant canvas
canopy providing shelter from sun or rain. This project illustrates
a successful meeting of traditional green oak timber framing techniques
and materials with a highly contemporary modern design and materials.
Photos of the construction progress are shown below the concept
drawing, including a close up of one of the laser cut stainless
steel braces in the green oak timber frame.
Below: The design drawing is starting to come to life. Shown
below is the first oak structure (calling it a pergola just does
not do it justice!) which was then topped with a glass roof and
used as a jacuzzi hot tub shelter.
