Make describes it as a contemporary take on the classic Victorian terrace. It is also affordable, with shared-ownership prices of £41,000 and deposit requirements as low as £2,050.
The scheme is being built in Aylesbury, the county town of Buckinghamshire, and is within easy reach of the town's facilities as well as the open spaces of the Chiltern Hills.
There are 30 homes available for shared ownership, out of a total of 94 homes. Prices start at £41,000 for a 40 per cent share of a shared-ownership one-bedroom flat, with a total value of £102,500, which falls inside the stamp duty ceiling of £125,000.
The two-bedroom flats start from £49,000 for a 40 per cent share of a property priced at £122,000, meaning a £2,450 deposit is required (based on a 95 per cent mortgage), while two-bedroom houses are £70,000 for a 40 per cent share (deposit: £3,500). There are also three-bedroom houses priced at £78,000 for a 40 per cent share (deposit: £3,900).
The development will be finished by the beginning of next month, and while the apartments have communal patios and gardens, some of the houses on the site have private gardens.
"The Serpentine offers an extremely rare opportunity to buy into a high-quality, contemporary development in this central location at an extremely affordable price," said Kush Rawal, head of sales and marketing at Thames Valley.
"These homes offer first-time buyers a real opportunity of getting their foot on the property ladder."
The development is five minutes' walk from the local station and trains from Aylesbury to Marylebone take about an hour, with an annual season ticket costing £3,520. The Government's proposed High Speed 2 rail service from London to Birmingham will pass by the area, to the horror of objectors who claim it will ruin unspoiled countryside.
However, the line is not close enough to the town to cause noise to homes. As for the site's green credentials: "The Serpentine has been locally manufactured, using responsibly sourced timber and is a pioneering example of high-quality, sustainable construction," said Justin Nicholls, of Make.
To qualify, buyers need a household income of between £18,000 and £60,000 and priority will be given to those who already live or work locally.
