Dolphin House: Windmill Road, Sunbury-on-Thames, TW16 7HE

Dolphin House is a residential conversion of 112 contemporary apartments in the bustling town of Sunbury. Offering a mix of studio and one bedroom apartments, Dolphin House is an ideal purchase for first-time buyers, couples or as an investment opportunity.

Sunbury is a suburb in the Surrey borough of Spelthorne, resting less than 15 miles from Central London. The town benefits from two railway stations which link to London Waterloo and it is located off Junction 1 of the M3 motorway.

Dolphin House is part of the Help to Buy Scheme

How does it work?

With a Help to Buy: Equity Loan the Government lends you up to 20% of the cost of your newly built home, so you’ll only need a 5% cash deposit and a 75% mortgage to make up the rest. You won’t be charged loan fees on the 20% loan for the first five years of owning your home.

Who is eligible?

Equity loans are available to first time buyers as well as homeowners looking to move. The home you want to buy must be newly built with a price tag of up to £600,000. You won’t be able to sublet this home or enter a part exchange deal on your old home. You must not own any other property at the time you buy your new home with a Help to Buy: Equity Loan.
