Total Project Price Guidance


Price Guidance can be found here -

The price guide estimates include the cost of your Radnor Oak building delivered to site, plus the cost of your contractor preparing the foundations & dwarf walls, erecting the building and fitting the roof covering.


Will my building require foundations?

Yes. A Radnor Oak building is a permanent addition to your property. The type of foundation varies subject to the type of building, however, typically, a strip foundation or raft foundation are suitable. We include details of your preferred foundations on our working drawings. 

Do Radnor Oak buildings require brick walls?

Our oak annexes and cottages, garages and outbuildings, home offices and summerhouses sit on dwarf brick walls. We detail three courses of bricks below floor level (this avoids concrete footings showing in the event that the surrounding ground is uneven) and three courses of bricks above floor level. Each course is two bricks wide with no cavities. Some oak posts sit on staddle stones (i.e posts located between pairs of garage doors and those on open fronted log stores).

Garden buildings such as gazebos and garden pavilions sit on staddle stones. If they include boarded panels these will sit on dwarf walls. 


What type of staddle stones do I need?

Staddle stones fitted between garage doors on garages & outbuildings will be 175mm square (the same size as the oak post) and 225mm high (the same height as the brick walls).

Staddle stones for gazebo’s and log stores can be chamfered. See the staddle stones we offer.

Where does Radnor Oak deliver to?

Radnor Oak can deliver frames nationwide.

Request a quote online and we will include the cost of delivery in the quotation.

What roof covering can I use?

Our buildings accommodate modern and traditional roof coverings which weigh up to 70kg / m2.  

Do I have to treat the structural timber components?

No. Oak is naturally durable and has ‘stood the test of time’ untreated for centuries. The ancillary softwood components we supply are Vac Vac treated. There is no need for you to add any additional weatherproofing to the structural components.

Your oak framed building will ‘weather’ externally over time. You can oil or stain your oak frame and weatherboarding for aesthetic reasons, however we like to leave everything natural. 

Do I have to treat the doors, windows & stairs?

Yes. Your joinery items will need to be weatherproofed as soon as you receive delivery.

We recommend that you protect your joinery products with a high quality paint or sealant exactly as you would for the joinery items in your house. 

Our joinery is very high quality and deserves some TLC.

Does Radnor Oak visit customers' properties?

As we specialise in oak framed building 'kits' which are erected by contractors or customers, we don't undertake site visits. 

If we have an 'Approved Contractor' in your area, they can undertake the entire turnkey operations to include site visits, quotations and the construction of your project See more here

Do you have a showsite?

Yes. We have demonstration buildings constructed near our offices which include a 2 Bay Kinsham (used as a workshop and tool store), a 3 Bay Norton (2 bays used for vehicles, 1 bay and the loft used as our oak floor-boards display), a 3.5 Bay Walton (used as a fully functional 1 bedroom annexe) and a large Gazebo with oak handrails and ballustrading. 

Please note that we operate viewings of our demo buildings strictly by appointment - please don't turn up without an appointment as unfortunately we won't be able to free up a member of staff to escort you to the demo site.

Call us on 01544 260727 to arrange your appointment. 

Can you send me drawings for my builder?

Yes. On receipt of a quotation request for our standard products, we prepare a detailed presentation to include visual images and the dimensions of the building. This is usually sufficient information for a builder to offer you an estimate of the site works.

Once we have received an order, we prepare a detailed set of working drawings which your builder will use when undertaking the site operations. If your builder is concerned about what they will need to include in their estimate, please do tell them to give us a call so that we can talk them through the expected costs of your project. 

Do you supply structural calculations?

Yes. We can release the structural engineer’s report for your project once an order has been placed. Our report covers the oak frame and ancillary timber requirements.  

Do I need planning permission?

Erecting a new building which is less than 4m in total height (i.e. our Stapleton, Kinsham, Walton, Lucton, Byton Low Ridge, Gazebos, Pavilions, Garden Offices and Summerhouses) may not require planning permission if other permitted development criteria is met. 

Erecting new buildings which are higher than 4m in total height will generally require planning permission. 

Replacing an existing building may not require planning permission.
