Denis Mikhlin and Jennifer Hall inspect the building work on their new Hollywood Hills house

It's the kind of investment you'd like to monitor.

Denis Mikhlin, 37, took a detailed tour of his new house in the Hollywood Hills that are being built to his exacting.

Jennifer Hall, the transporter actress and her supermodel girlfriend Jennifer Hall, 23, struded around the building site with an architect and a site foreman who led them through the process.

Jennifer, 23, looked summery in a floral print dress and denim jacket, while Denis, 37, her boyfriend of just under a year, seemed more casual in jeans and a brown jacket.

The pair have been staying in the Four Seasons Hotel in Beverly Hills since the house is under renovation and they have already begun to shop for furniture and other home furnishings, which is ready to move in.

On a cruise around the Caribbean, the couple profited from being temporarily based at an LA base by spending almost a month enjoying some winter sunshine.

They spent over three weeks in Cody and Antigua, as well as Elizabeth Smith's lavishly lavish new years bash.
