The object of their affection is a four bedroom 1930s art deco house in Poole, Dorset and they are about to embark on the biggest spending spree of their lives. Yet they set off without an architect, a surveyor or, indeed, any plans. Making it up on the hoof seems to be the order of the day.

This week both sets of developers are in their 20s and neither are letting a lack of money or experience stop them having a go at developing. But super tight budgets combined with unseasoned instincts means that they're also taking huge risks.

Sarah Beeny is in Lincolnshire revisiting Philip and Steven, who three years ago left their successful London careers to take on a run-down barn in the middle of the Lincolnshire countryside. But have their dreams come true or turned into nightmares?

Eighteen months ago, Kim Maoate decided to start a career in property developing. She gave up her high-paid job, re-mortgaged her house and bought a wreck 170 miles away from her home in South Wales. But that's when the nightmares began…

Simon and Caitlin Eisenmann want to climb the property ladder and be able to buy the house they are currently renting. They're £7K short and decide to buy an unmodernised property. They plan to renovate the property and sell it for a profit of £7K - all in just 12 weeks.

Terry and Sarah are renovating their bungalow in Tonbridge, Kent. They plan to add a "Garden Room" type extension to the back of the house which will significantly increase the size of the kitchen and draw attention to the huge back garden, and also extend into the roof to create two further bedrooms.

We've crunched up all our credit, the market's got serious jitters and you'd think novice property developers would be pulling back. Not a bit of it! In this week's Property Ladder, The Beeny has her hands full with two sets of first-timers taking on not one, but two properties each.

Recently divorced, Jonathan Topps had been forced to live in his friend’s spare room for 6 months and was itching to get back onto the property ladder. With London prices so high, he had decided to embark upon a new career as a property developer to help him achieve the house of his dreams, and hoped a 3 bed Victorian terrace in Sydenham would be his first success. Even though he planned to do the majority of the work himself, his £20,000 development budget seemed optimistic, particularly as he’d bought the property without even the most basic survey.
