Emotional moment man on Grand Designs strolls through late parents' home filled with memories before knocking it down to build 'wellness' house to care for his sick wife

This is the emotional moment a man on Grand Designs strolled through his late parents' home filled with memories - before knocking it down.

In the latest episode of the Channel 4 series, Tony and Ara sought to build a 'wellness' house in a woodland clearing near Henley-on-Thames.

Ara, who once worked in the corporate world, suffers with increasingly fragile health due to an autoimmune condition and needed her own space to help her heal.

But in order to achieve their dream home - with an estimated building cost of £800,000 - the couple have to sacrifice the home of Tony's late parents, John and Betty.

A moving video from the new episode shows the moment the couple and host Kevin McCloud walked through the 1960s bungalow for one of the final times, reflecting on the 'memories' they made there.

Looking at the panelled walls and unique mosaic floor with a clock at its centre, Kevin couldn't help but comment: 'That's rather beautiful'.

Ara added: 'It's all been done with love, and you can feel it.' And pointing to the room next door, she even revealed: 'We got married in that room!'

The couple had moved in with John and Betty seven years ago to take care of them - with the house holding a 'treasure trove of memories'.

But Tony, a health researcher, said: 'I think for me, I've worked on a strategy to be able to let go.'

The couple wasted no time with starting the demolition process and beginning to build the new home, with work beginning in 2019.

Tony said: 'For so many years both practically and psychologically I felt a little bit hidden in the shadow of what my dad had done, but now it's really my project.'

But the building process was far from simple as Tony took on the project management and building work himself - even discarding his architect's plans, despite his 40 years of experience.

To cut costs, Tony said he would 'learn on the job', but just months in, he was faced with a roof that wasn't water-tight and mounting prices.

The project then descended into 'chaos', with Tony suffering a fall, and endangering Ara's health even further.

But through it all, Tony remained calm in his philosophy that 'if you enjoy the process, it doesn't really matter how long it takes'.

The result of Tony and Ara's efforts will be shown in Wednesday's episode of Grand Designs.

Last week, Grand Designs viewers were 'moved to tears' by the 'best episode ever'.

Kara, Jonny and their young family won over hearts across the nation in their bid to build an accessible home in the Pennines in West Yorkshire.

Kara was left paralysed after suffering a seizure on a holiday to Spain in 2019, after which she was unexpectedly left in a wheelchair for life.

The mother-of-two was diagnosed with neuromyelitis optica (NMO), an autoimmune condition that flares up and threatens damage to the nervous system.

During the episode, she and Jonny built their dream home featuring stunning interiors and sweeping countryside views - while accessibility features meant she could regain some of her former independence.

After Kara emotionally broke down in tears confessing she'd been able to get her 'freedom' back, viewers also found themselves sobbing and branded it the 'best episode ever' of the show.

They took to social media to write: 'In all the years of #GrandDesigns we have a winner!! The house.. The couple.. The work ethic.. The styling.. The amazingly fabulous dog.. All bloody brilliant';

'Stunning design and attention to detail to deliver an incredible home. This is what Grand Designs is about. One of the best builds in the 25years of the show';

'I've never rooted harder for anyone on Grand Designs than I did tonight';

Grand Designs airs at 9pm on Channel 4 on Wednesday.
