This was completed two years later.
"We started with a green field," he said of the 55-acre farm which now boasts 100 boxes, five walkers, a spa, swimming pool and three gallops.
"We're very lucky here I suppose that we are self-contained with a three-and-a-half furlong circular gallop on sand and fibre, as well as a six-and-a-half furlong woodchip and five furlongs on grass."
The facilities are so adequate that the need for horses to work on the nearby Curragh gallops are rare, and on those occasions, or when Halford is attending a race meeting, assistant trainer Fabian Burke is always on hand to keep an eye on the operation.
While Halford can honestly reflect on a career of many highs and lows, he will always remember Casamento as the one who provided him with his first ever Group 1 success when landing the Racing Post Trophy at Doncaster in 2010.
The son of Shamardal was one of only two juveniles that Halford had been sent at the time by HRH Sheikh Mohammed Al Maktoum, but it is a partnership that has remained ever since, with Al Qahwa, Vitello, Protocol, and Tonkinese among the current residents running under the Goldolphin banner.
Not surprisingly the Racing Post Trophy was to be the first of many Group wins in the latter years, and Certerach then added his name to that roll of honour when romping home in the Group 2 Dubai World Cup in the spring of 2014.
By his own admission at the time this win was seen as 'beyond his wildest dreams' but one which had given the trainer a timely boost for the Irish season which lay ahead.
While Casamento has long retired to fulfil stud duties, Certerach is still very much part of the team at Copper Beech Stables and Halford is hopeful that the seven-year-old will sparkle over the Irish Champions Weekend, having failed to impress on his last two runs at Leopardstown after a long lay-off since last summer through injury.
"He was due to run at the Curragh last week but he was withdrawn due to the soft ground.
"He's now entered for the Irish Stallion Farms EBF 'Petingo' Handicap at Leopardstown and also the Irish St Leger, but again all will depend on the ground," Halford said of the Paul Rooney-owned gelding which is among 17 horses so far being aimed at the Leopardstown and Curragh racing spectacular.
"We also have Toscanini for the Derrinstown Stud Flying Five Stakes and Vitello is entered for the Group 1 Moyglare Stud Stakes. She was very impressive in her last run when winning at Fairyhouse in June," he said of the daughter of Raven's Pass.
"Raydara (HH Aga Khan) is entered for the Group 1 Matron Stakes at Leopardstown on Saturday. She is a Group 2 wining two-year-old and ran a very encouraging race last time out to be second in a Group 3 race also at Leopardstown. While she has a preference for fast ground we are really looking forward to running her as she has come forward in her homework.
"Among the big handicaps, we should be well represented by Portage (Godolphin), Hasanour (Richard McNally), Eastern Rules (Simon Hales, previous winner in Dubai), Russian Soul (Mrs Antoinette Kavanagh, previous winner in Dubai), and Shadagann (Paul Rooney) to mention but a few.
"It is such a wonderful showcase of Irish racing," Halford said of the upcoming two-day festival. "To have five Group 1 races in one weekend is quite special, and something that was needed here.
"Irish racing is very healthy right now though, and it is encouraging to see so much support coming from the Irish Government."
