Just 20 minutes outside Edinburgh, Rosslyn Chapel is nestled alongside the village of Roslin which it is thought grew up around the Chapel to house the craftsman building it.
Rosslyn Chapel was fairly unknown until it featured in Dan Brown’s book and visitor numbers soared. Two years later the chapel appeared in the film The Davinci Code. Further raising the Chapels profile with visitor number up from 30,000 to 175,000 in the aftermath of the blockbuster film. With visitor numbers so high the old visitor centre was insufficient. Carpenter Oak were approached to build a new timber engineered visitor centre.
Our innovative oak frame structure is an unusual combination of green oak and steel connections. A post and beam structure up to eaves level with longitudinal scissor bracing fabricated from 120mm x 120mm oak members, with laminated structural board. To add to the interest the 25m long roof is stepped along its length. Rather uniquely the post and beam frame is jointed using resin bonded steel rod and plate connections designed by project engineers Momentum Structural Engineers
The geometry of the roof, combined with the challenging site conditions necessitated a complete trial assembly at our Wiltshire workshops to ensure that once on site the erection would be flawless. Once assembled on site, the structure required thirty-six manually operated chain hoists and some very careful coordination to lift it into place. The £230k contract was won in open tender by our Timber Engineering division.
Carpenter Oak worked alongside Page Park architects of Glasgow on this exciting Scottish timber-framed building. The visitor centre at Rosslyn Chapel near Edinburgh was made possible by funding from the Heritage Lottery Fund and Historic Scotland.
The timber engineered roof structure of the visitor centre at Rosslyn Chapel has a diagonal struts system and is made of oak (which has been stained, explaining the darker appearance). Our clients are delighted with their timber engineered visitor centre and love the modern appearance of the building in contrast with the historic chapel. Visit Rosslyn Chapel website to find out more about the Chapel and of course the timber engineered visitors centre.
Devon (UK) based award winning specialists in the design, construction and raising of oak timber framed buildings. We have a dedicated team of Project Managers, Frame designers and Carpenters who work closely with clients and architects to deliver a wide variety of bespoke oak frame projects across the UK, Europe and beyond.
We celebrate the beauty and joy of timber frames in many different styles and raise over 60 frames a year for inclusion within schemes ranging from oak sunroom extensions to extensive high-end architectural oak houses.
We love wood, we love design and we love a challenge.
Budget considerations are of course one of the primary factors for anyone undertaking an oak frame self build project whether it's a new build oak frame or a timber frame extension. 'How much will it cost?' is therefore a question which will be asked over and over and will almost certainly form a central thread of your project.
Overall build costs for a complete new build oak house typically vary from £1,500 to £2,000+ per square metre (referring to the useable area of the lower and upper floors added together) i.e. for a two storey property times the area by 2. We would suggest that you budget from £1,200- £1,800 per sqm (or £120-£180 per sqft).
For extensions we would suggest budgeting from £2,000 per square metre - don't forget to add VAT (for UK customers). It is worth noting that guide price is for a complete build based on a contractor doing the work with the timber frame is usually a 20-30% proportion.
If you intend to self build then expect to budget toward the lower end of the scale (although of course it may take longer!). There are several caveats with this guide price including the following key considerations:-
At every stage your decisions will affect the overall costs, from the complexity of the design to the level of finish. Engaging an architect will almost certainly save you money in the long run. Getting advice from us on the timber frame concept prior to going in for planning will minimise the risk of sending your architect 'back to the drawing board'.
We are happy to discuss your ideas with you at an early stage and can offer you advice along the way. It is helpful for you to build a scrapbook (you could use Pinterest) of your ideas and wishes – this makes your brief to us and your architect much clearer. Once you have a plot in mind we would encourage you to come and see us in the show barn at our yard to discuss your ideas in more depth and help you establish a concept design and rough costs.
You can meet with one of our frame designers and an architect if required (Roderick James Architects offer a free initial consultation). We can offer you an estimate for your budget costings at that stage based on a timber frame sketch scheme. You will then be in a position to draw up a planning application, knowing that you will be able to achieve what you want with the frame. We can offer you an accurate estimate based on a timber frame sketch scheme once you have architects drawings. Once your planning application has been approved we can get going on a detailed frame design for you.
All of our Oak is from sustainably managed woodlands located around a single sawmill in Normandy, France (PEFC certifified). When this mill is unable to fulfil our order we divert to an alternative mill in Germany. The mills have access to a plentiful supply of exceptionally well managed and very high quality timber.
Why not use UK sourced oak, I hear you ask? Sadly, the lack of investment and good timber management for hardwoods in this country over many years means our domestic supplies are generally of a lower quality, inconsistent supply and can be more expensive. Although the situation will gradually change, it means that currently continental Oak is the best option for our framing. Carpenter Oak Ltd are investing in the future of UK woodlands.
For every tree used in a project we will donate 10 Oak saplings to an organised planting scheme in the UK
Douglas Fir and Larch all comes from sustainably managed UK forests.
Just to clear it up from the start Green refers to the amount of moisture in the timber rather than the colour!
Large section ('heavy') timber framing has a style and rawness of its very own which is everything to do with the material. Its style, rhythm and methods have developed hand in hand with the use of timber in its unseasoned state. Any potential problems that the shrinkage and movement of the timber could create are designed out at the detailing stage, creating modern buildings which retain all of the beauty and stature of their historic predecessors whilst meeting and exceeding our stringent modern standards of weathertightness, airtightness and insulation.
Oak has always been used by timber framers in its 'green' state for a variety of very good reasons:

Usually this kind of work requires a site visit, advice and a report before the work is agreed in discussion with the engineer, architect and conservation officer. We regularly work on a consultancy basis during that phase and if there is a frame to build at the end then we can take that on too.
Adam Milton (Managing Director) was one of the carpenters involved in the roof repair after the Great Fire at Windsor Castle.

We regularly build oak frames for inclusion in renovations and barn conversions. A timber oak frame structure is ideal if the existing building is in structurally poor condition. The oak frame can slot into the fabric of the building to then carry the new roof etc.
You will need to find a builder to undertake the project as a whole but we are happy to design and build a frame for you or to give your builder dimensions. We can deliver this to site either as a kit or with the carpenters who made the frame, dependent on the size.
Yes. If you are looking for a complete build or ‘Turnkey’ service, we can offer a solution to include each stage of the process, from the feasibility assessment, design, management and construction, right through to completion. We pride ourselves on being adaptable as every client is different. We can offer a number of routes for you and your project, depending on how involved you want to get. We aim to understand your particular situation and respond to deliver what you need. For many people that means us working as a contractor alongside your architect and builder, for others, involvement at each stage or a self build project. Get in touch to find out which route would suit your project best and we can deliver a range of options from a finished frame to a finished house, ready for you to move into.
