The £11m project, which is backed by Mars Petcare, will include a cutting-edge imaging suite, state-of-the-art treatment facilities and a new linear accelerator.
Plans also include separate cat and dog waiting areas and client walking and comfort areas, seven operating theatres, 15 consultation rooms, recovery suites, lecture halls, a dedicated ICU department and plans for a future hydrotherapy suite.
Daniel Hogan, operations manager at Southfields (pictured right), said: "This is a really exciting time for Southfields and our relocation will provide the region with one of the largest and best-equipped veterinary centres in the UK.
"The team and expertise have grown significantly in the past 18 months. We are very excited to continue to expand the unique and innovative offerings in patient care at our centre.
"Increasing in size will also enable us to provide a dedicated staff wellbeing area and an education centre and lecture hall, which will offer some very exciting qualifications and courses for the wider profession.
"Since our rebranding in 2017, we pride ourselves on leading the industry as a truly multidisciplinary centre with specialists from across the globe, including one of the most illustrious oncology teams in the country. Once this new site is launched, we will be able to offer an even more comprehensive service to our clients and patients."
