When the opportunity arose to build a timber Gridshell for the Weald and Downland Open Air Museum, we jumped at the chance. The basic concept is simple but the execution is anything but!
For lightness and strength the Gridshell is without equal. Once you have solved the problem of how to joint the chosen timber laths into long lengths, often over 50 metres, and assembled the grid onto the scaffold, the next challenge is to achieve the 3D form without over-stressing the joints. Though a lightweight and fragile structure in the temporary condition, once everything has been ‘locked off’, the structure becomes remarkably strong. The total weight of the timber lathes used in the Downland Gridshell, which is 50 x 15m on plan, is a mere 6 tons!
Our last major Gridshell project was for the Crown Estates and forms a visitor’s centre to Savill Gardens, in Windsor Great Park. The structure is fabricated in Larch grown in the Crown’s own forests and is of exceptional quality – close grained and with minimal defects.
Visionary buildings require visionary clients, and in the case of both these buildings, this was certainly the case.
"Seems a long time since we finished with the garden room project but we have to say that it has been a huge success in every aspect. The room has become the place of choice for visitors. I can guarantee that everyone, yes everyone who visits, is blown away by the frame."Mel, Moat Farm
"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
"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."Ray Nicolaides
"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
"We have constructed several buildings using Oak frames designed, manufactured and erected by the Green Oak Carpentry Company. We are pleased to confirm that their work is accurate, well detailed and delivered on time. They are knowledgeable and we find working with them easy and straight forward. We therefore have no hesitation in recommending them."Robert, Trembath Associates
