Shanique Davis, from Wolverhampton, has now visited her new home in Sedgley, but says the good news still hasn't sunk in after she won it on Wednesday.
The 23-year-old said: "It's beautiful. The house is better in real life, it looks amazing.
"It was just so surreal because I didn't expect it.

"I don't have the keys yet as we'll have to arrange the paperwork.
"When I went to work they had balloons, everyone is really happy for me.
"I told all my family on Wednesday night, everyone was happy and crying."
Along with the £500,000 house, Shanique won a Jacuzzi hot tub, a Range Rover Autobiography and funds to pay her council tax for the first year.
Shanique, a support worker, was saving up for a house with her fiance Mark Myrie, who she is marrying in Jamaica in December.
Her ticket was chosen in a random online generator in the Win Your Dream contest at the house, 53 Catholic Lane, at 4pm on Wednesday.
Inside there's a spacious living and dining room with wood-burner, a utility room, downstairs cloakroom, ground-level cellars, and a large breakfast kitchen at the rear, leading out onto a sun terrace.
Off the living space, a new study has been created with a glazed oak partition.
The first floor is made up of four bedrooms, including a master en-suite and a comfortable family bathroom.
Planning permission has also been granted to extend the property to make a new garage, a first level family space and a second level master suite.
As part of the draw, Steve Bull accepted a cheque for £2,500 on behalf of Promise Dreams and Vanessa Simmons, head of fundraising for Ronald McDonald House Charities (UK), was handed a cheque for £10,000.
Tickets to enter the raffle were £2.
It comes after Mike sold his own house in Shropshire via a similar raffle. It was won by 23-year-old Jemma Nicklin from Bilston who was at the time living with her parents.
