Inside the first UK 45m roundhouse

The first 45m (RH45) roundhouse building in the UK, at Fulling Mill Farm is nearing completion.

It will house a herd of 100 Simmental-cross cows and 200 followers and includes a central handling system and crowd pen, which is accessible by all of the seven pens that surround it. 

Each pen is designed to hold 18,000kg, which equates to about 30-50 animals, depending on their size.

The spherical design with central handling area is fundamental to the idea of the roundhouse, as are the completely open sides and “tented” roof with central air outlet.

Farmers Mr and Mrs Eggert-Hobbs explained that lower labour inputs, improved animal welfare and efficiency were key reasons why they had decided to make such an investment.

“The handling system means we should be able to handle the same amount of cattle as in our old system, with one or two people, rather than four. The “safe area” is also particularly appealing to me,” explained Mrs Eggert-Hobbs.

She has modified the design of the handling system from the 30m version to include an additional pen for segregation, allowing stock to be split for sending to market or tagging, for example.

She said: “Getting labour in the South East is not only expensive, but also difficult. If I can halve the number of men I need to bed up and feed up, it’s a big bonus, and with the roundhouse I expect to use 35% of the labour I would have used if I had put up a conventional shed.”

Business expansion

The roundhouse has offered the business a means of expanding the herd. Having given up dairy farming 12 years ago, beef appeared the best option for the resources available, however they were limited by farm infrastructure.

“We farm 1,000 acres, so we have always had the land, but were limited by the buildings, which were put up in 1946,” said Mrs Eggert-Hobbs.

When looking at putting up a conventional building, the cost of concreting loafing and feeding areas meant it was not viable. However, the roundhouse ticked all the boxes.

The pens have a chalk base, which has been consolidated and sealed, with the outside surrounding feed area concreted and the area beyond this covered in tarmac plainings.

The new shed is also hoped to boost efficiency. “We wanted to put the economics back into the system and finish stock quicker,” she added.

The business currently finishes 60-70 cattle a year, but it is hoped that the roundhouse will help reduce finishing times by three weeks and boost this number.

“The roundhouse gives us options to use it as we like. At the moment we have stock of mixed ages together, but the pens will allow us to separate animals as we want to.”

The new building and existing sheds give the farm scope to farm 500 head, with the aim in the future of renovating one of the old sheds and potentially putting up another roundhouse.

Welfare benefits

The roundhouse is also hoped to bring big welfare benefits – something Mrs Eggert-Hobbs sees as becoming even more important in the future.

“I think farmers will get clobbered for improved welfare in the future and I want to be prepared.”

Good ventilation is also a bonus of the roundhouse and an area Mrs Eggert-Hobbs has noted of particular importance following pneumonia problems in the past.

“Three or four years ago, I was rearing bull calves from a local dairy producer and was experiencing big problems with pneumonia. It was so disheartening – I was pulling out dead calves nearly every day and spending a lot on the vet.

“In the end I just chucked them outside and I probably only got one case after that. It was a big eye opener and made me really conscious of ventilation and air flow.”


At about £149,500, the building is a significant investment, but one both the Eggert-Hobbs and building designers Geoff Simpson and John Allison, of the Simpson and Allison Group, think will bring significant payback.

The emphasis should not be on what something costs, but rather what the potential benefits are, said Mr Simpson.

“The initial cost may be high, but the paybacks could be rapid in terms of improved animal health and reduced labour, vet costs and handling.”

A general project, excluding groundwork, would be about £1,050 a dairy cow place versus £1,317 for two-row cubicles or £1,052 for two-row kennels plus mats (DairyCo)

Key attributes of the RH45

  • Twice as big as the original RH30 and capable of holding double the number of stock
  • It has a diameter of 45m, circumference of 144m and an internal area of more than 1,500m2
  • Holds just over 300 beef animals at 500kg and 180 dairy cows
  • Tent-like roof made of high-tensile PVC-coated polyester fabric
  • Roof is erected in one piece on the ground and hoisted up using a hydraulic lift pack, avoiding safety concerns from working at heights
  • Open sides and central hole/air outlet
  • Seven pens arranged in “segments” around the central handling system, with all pens having easy access to this
  • Human escape gaps along every pen divide
  • Outward-facing feed area surrounding the outer edge
  • Water troughs can be fed by gravity from tank, removing the need for a ball cock, keeping water flowing and preventing water from freezing
  • Easy to feed or bed up by going around edge of building
  • Promotes natural herd instincts as animals can see each other and surrounding area through open sides – reduces stress
  • Basic cost: RH45, £149,500; RH30, £57,000


Who can use it?

  • Fattening cattle, calves, dry cows, dairy cows, fattening pigs, dry sows, sheep
  • The RH45 makes the round building concept applicable for milking cows for the first time. One has been erected in Nottingham for this purpose and will have three robots adjacent

Key performance figures seen from the original 30m roundhouse

  • Newcastle University has found the heart rate of cattle kept in the roundhouse to be significantly lower versus those in conventional sheds
  • Stock’s reaction to the introduction of an unusual object, as well as ongoing cortisol levels, also point to the roundhouse reducing stress levels
  • 2007 calculations of the RH30 showed a potential £20,000-a-year saving from using the roundhouse. This included a 50-60% reduction in labour and a potential to finish cattle three weeks earlier

Why choose the RH45?

  • Improved safety and reduced labour through integrated handling system
  • Better ventilation – open sides and central air outlet
  • Aesthetically pleasing
  • Improved animal health and welfare
