Parley equestrian centre is now one of the biggest in the region after 16 new stables were built, bringing the total number to almost 70.
It is the latest development at the centre that is also planning an indoor school to go with its existing facilities that include an all-weather showjumping arena.
Jane Wyatt, who runs the equine business, said the extra stables were filled immediately and more are set to follow as there is a waiting list.
The Dorset centre now has over 100 horses, including 13 full liveries, over 50 DIY liveries and more than 30 grass liveries.
It holds regular showjumping and dressage events through the year and after its launch in 2009 has grown with astonishing speed.
Jane, who also trains and rides horses and came in the top ten at this year’s Horse of the Year Show, said: “We now have 67 stables and they are all in use.
“We had grown out of our existing facilities and need the extra capacity that the stables have given us.
“We are growing quickly and a new school will be built soon, which is extremely exciting. Ultimately it will be indoor.
“We are looking for sponsorship to help us fund the development of the centre where we have more than 100 horses.
“Next year we will be holding showjumping and dressage events.”
