Planning & Listed Building Consents

Our aim is to shield you from the stress and hassle of the planning process. At the preliminary site visit our designers should be able to provide you with an understanding of whether full planning permission is required. Once an order is placed, our two full time planning consultants with a combined 50 years of experience, will liaise with your designer to ensure that we submit an application that gives you the best possible chance of an approval. Prime Oak have an excellent record of gaining approvals whether it be first time round or through winning appeals on what we believe to be unjust refusals. Alternatively, these experts may advise that your proposed building falls within permitted development and will gladly seek to obtain a certificate of lawfulness should you require.

we take your vision and
turn it into a bespoke,
organic structure.

Building Regulations

We work closely with a company of independent building inspectors to establish the quickest, and most efficient approach to obtaining an approval. Whilst being as diligent as your local authority surveyor with regards to how your foundations are built, they will take a far more commercial and realistic approach to secure a practical approval of your building.


If planning is required, once an application is validated your Local Authority will usually take 8 weeks to provide an initial decision. A further application may then be required for any alterations requested by your Local Authority. Our lead times are normally between 10-14 weeks from planning approval & receipt of the relevant stage payment. Construction times vary from 2-3 weeks for a simple garage up to 7-8 weeks for a garage complex, but an extension is typically between 4-5 weeks.

Seasoned Oak

All of the structural frames for our garden rooms, orangeries and conservatories are manufactured using air dried seasoned Oak from our own extensive drying yards. Each of our yard workmen have a wealth of experience and knowledge of Prime Oak’s products and undertake comprehensive training on how to carefully select oak from our drying yards, based on both quality and suitability.

Having our own drying yards therefore means that when individually selecting our timber for each project our quality is second to none, giving us total quality control. As part of our quality control procedure, we tend to reject on average 25% of our Oak during the drying process.
