How to Build a Timber Garden Building: Planning Permission

One of the most common questions we get asked is whether planning permission is required for timber garden buildings. If you want to convert an existing garage into habitable use, building regulations will apply. In the UK, you can build a variety of timber buildings in your garden without the need for planning permission. However, it is important to view specific information for timber building conversions on the government website.

What Our Clients Say About Us

  • Admin Ladies. Just a quick note to say thank you so much for great service! Both in the office & the boys on site have completed a superb project & I’m delighted! Thank you, Su Pedersen

    Su Pedersen from Gloucestershire - Received 24th April 2018
  • Hi Sarah Many thanks for our stables and the guys were fantastic. I’ve liked your Facebook page and I’ve sent you some more photos for your page!! The doors are the perfect height for Briagha and Maisie and I thought Briagha in the corner might be in the dark, but the light strips on the roof and the windows have made it nice and bright for her. The bigger box is my spare for a potential Briagha and foal – not next year, but the year after!!! Another little Falabella hopefully! Who knows – I might need you back to build some more stables !! Thanks again. Pauline Young

    Pauline Young from Aberdeenshire - Received 31st August 2016
  • Dear Sarah and Natasha, Just to let you know that our horses are now as pleased with the beautiful mobile shelter from Prime Stables as we are – it took them a little while to get used to it especially as the sweet chestnut tree behind it is currently bombing the roof with chestnuts! Thank you all, including the guys who built it and put it up for us. With best wishes, Laria

  • Dear Sarah, Many thanks for final paperwork, and I understand Vikki's horse - "Apple" has quickly taken to her new shelter, and Vikki is very happy with the building. I've not see it myself, though I've seen the videos! I've forwarded your email to Vikki, and I'm sure she will also click that Facebook link for you too. Thanks again, and kind regards, George
