Callow Farm
1 / 8
The front elevation of the newly repaired barn is shown here in its context with the farmhouse, which has an expressed ancient cruck frame on the gable which could be as early as 12th century.
The barn doors are set back against the frame and may be used as shutters. They are very handsome pieces of joinery; note the five diminishing rails and braces to each leaf and the absence of a swinging stile (vertical rail) on the outer edge of the door to reduce weight.
The barn is a small 3 bays structure with a centrally located cart entrance bay. Mezzanines have been inserted into both the end bays with an elevated walkway (allowing access over the tie beams of the trusses) connecting the two areas. This is a light touch conversion that does much to retain the open character of the barn.
We fabricated and installed the four columns you see here supporting the mezzanine. Jointing cruciform galvanised steel plate to the column heads and bases and counter boring the fixings (leaving them exposed but set just below the surface) gives an unfussy, contemporary look.
The combination of the polished concrete floor, plain white decorated surfaces and insertion of new materials such as sandblasted Oak, galvanized steel and the glass balustrade, creates an appealing juxtaposition with the rugged beams of the original structure.
We do not recommend sandblasting historic frames as this destroys the patina of the beams as well as the assembly marks, and sometimes other fine cut marks, which may be part of a code cut by the master carpenter instructing his team as to what joints he required.
This picture taken from the gallery gives one of the best views of the historic carpentry. The roof structure is a little unusual with twin purlins used in an unusual configuration. The lower purlin is threaded between the two truss rafters, the curved inner ‘curb rafter’ and the straight outer rafter, whereas the upper purlin is clasped at the junction of the collar to the truss rafter.
You can see in this picture that we had to replace quite a number of the original rafters with fresh sawn oak, as many of the softwood round pole scantlings were badly damaged by beetle. This is something we are reluctant to do unless absolutely necessary and the original rafters are deemed unserviceable.
Good design decisions make a difference; here the glass balustrading does much to lighten the appearance of the galleries and staircase, lessening their impact on the space and setting off the frame nicely.
“"I wanted to drop you a quick note to show my appreciation for your guys efforts today; they were a pleasure to have around the house and worked hard to get the frame up today."
Paul, Contracts Manager
“"Just a quick note to say thank you for sending such a great team to do the work. As well as clearly being very hardworking and hugely skilled, Mick, Andy, Clark and Dave were all exceptionally pleasant, considerate and cheerful guys to have around, and as such a huge credit to Green Oak."
Julia, Crabfields Farm
“"We wanted to write to you to express our profound gratitude for the excellent work you have done on our building scheme. It cannot have been easy to pick up the project from another architect when there were still a number of issues unresolved, but you have done so brilliantly and remained calm throughout, even at fraught times. We really do appreciate that you have gone the extra mile for us. We have all enjoyed working with you and have been so impressed with the quality of your work."
Alastair, The Early Years Project
“"Everyone is very impressed with the finished result and I thought I would just take the opportunity of belatedly giving my thanks to you and your team for a job very well done. I have submitted the bridge for a Civic Society award for next year and have every expectation of its success."
P White, Northholt & Greenford Countryside Park Manager
“"Thanks for the excellent job which has just been completed on the Oak Frame extension to the above property. Not only is the quality of the work faultless, it is a true work of art, which will bring endless enjoyment to me and my wife. The end result has surpassed our wildest expectations."
