This project was one of the most rewarding of projects to date.

The first part of the project was to design a beautiful New build timber frame barn/ garage along side the main building. Work was well underway carefully dismantling the existing structure of the main building which gave us some time to concentrate on the design of the barn.

The barn was not your standard barn, great care went into the design of every little detail. Euan the owner/ Architect used his immense fountain of knowledge both in design and also modern technology and packed it all into this structure. From the outside the building blends in beautifully with the country side and looks as if it was there for years. It has the best of both worlds, not only does it look good but it will also achieve fantastic U-values.

I will update with detail sections later.

Here are some 3D model shots and how the job currently stands.

The Barn Timber frame design was not straight forward. There was many split levels in the building along with some large openings and large heavy attic trusses.

BMK took great care in the design of all components and generated a highly detailed model to try minimize complications.

More detail shots. The devil is in the detail.

This is how you finish off the corner junctions. Just like a beautiful piece of furniture.

Lets look at the roof

Finishing touches going into the hips to the rear.

BMK will keep you updated when I return to site early next year.

I will post the on going design and pictures for the main building in a few weeks. You wont be disappointed. Great credit needs to go out to all the design team and all the hard craftsmen on site, but most of all Euan Borland for driving on the project and leaving no stone unturned. I look forward in seeing you after Christmas.
