Alternative Oak Frame - Non Load Bearing

With our oak frame option you get the look of an oak frame building, but not a structural Oak frame. The main structure would be achieved by using one of the above frames or one the client specifies, the Oak A frames would then be produced and fitted to the inside of the frame, with mortice and tenon joints, dowels to hold in place, and any diagonal bracing required ( more for aesthetic appearance ) we can accommodate for any design the client wishes to use. How many A Frames needed ( as its not structural ) is limitless.

This frame does overcome the problems that can occur with oak frames:

  • Movement
  • Cost
  • Damage to the finish product ( water stains ) etc
  • Flexibility due to structural needs
Larson Truss Frame

A Larson truss is an Canadian design and commonly used over here, however the more eco friendly the new propriety's are becoming there is more demand for a high insulated Frame. In certain circumstances the Larson truss is a very cost effective alternative.

Built to your requirements its a truss that spans from floor slab to facia board height and is installed @ 400 - 600c and then clad externally with a 9mm OSB/Smart ply and 25 mm counter batten. These trusses can be built from 200 - 600mm giving you a void to full fill with insulation of your choice.

Log Clad Frame...

Log clad frames or chalets/cabins can be ordered to your own specific design Using one of the above frames.

They are then clad with a log lap cladding to give the feel of a log built building.

Glulam Portal Frames

Fast becoming one of our specialist areas.

We can create a glulam portal frame using glulaminated beams as the main support structure, with connection details to suit your specific design.

Glulam beams are then on show externally and internally giving the whole frame a very bespoke and unique look. Please contact us for this bespoke way of building with timber.

Roofing...

Most of our roofs are cut roofs and will be individually designed to the current project however typically :

  • 200 x 45mm Graded treated softwood rafters @ 400 - 600c
  • Glulam or steel Ridge beams
  • 9mm OSB/smart ply laid externally over the rafters
  • 25mm Counter batten
  • In some cases we will lay a Tyveck moisture barrier for water proofing the frames under the counter batten. Giving you a 90% water tight frame before the roofers are on site!

What our customers say...
  • Dan and his team at Onsite Framing have been excellent from the moment we started the quotation process to the completion of the contract. It is inevitable on a contract like this that things change but Dan coped with each one with a smile (grimace?) and has helped with ideas to overcome issues that arose during the build without drama...

    Andy Goodman - Mylor Bridge, Cornwall

  • As the site for the new house has very limited access, I found Onsite Framing ideal for the job as any problems or changes could be easily rectified.

    Friendly and helpful, I would happily recommend them - in fact I already have!

    Moira Leedham - Towan Cross

  • I would use this company again they did a good job, started when they said they would and finished when they said they would. All the builders were easy to talk to and pleasant to deal with. No problems, there were just challenges. I now have a house which is warm and well insulated.

    June Bertram - Veryan

  • We looked at several builders and build methods for our new home, but standing out from the rest was On Site Framing. Their approach was well suited to us and lends itself for the flexibility needed to achieve the bespoke house we required. We would not hesitate to recommend Dan and his excellent team...

    Michelle and Alan Williams - Trevellas

  • We are really pleased to have appointed Onsite Framing as our main contractor to substantially remodel and extend our home. In a project of this scale and complexity good communication is key and a real strength of Dan Fielder and his team was to be able to communicate effectively, liaising between ourselves as client, our architect and structural engineer...
