Popular BBC daytime programme Homes Under The Hammer regularly visits Wales to track the journey of an auction property from Welsh wreck to wonderful abode that hopefully makes money for the buyer too.
Sometimes presenter Martin Roberts is struck by the awful state of the property or enthusiastic about a low guide price, but it's probably accurate to claim that he has never spotted something so small that has made him giggle during the 26 series the show has been on air.
A three-bed, semi-detached house in Llanelli had already impressed Martin with a guide price of £110,000 but it was all about size and proportions, big and small, that made this property memorable.
The size of the house was a hidden bonus that has Martin happy, with a ground floor that keeps going at the rear via a spacious single-storey extension not hinted at from the street.
Martin is very pleased to find it, and it even surprises the auctioneer selling the house via virtual auction who calls it a 'Tardis' property.
Cue the theme music from TV programme Doctor Who in the background, but at least Martin's voice wasn't changed to that of a Dalek.
Doctor Who popping into the show at the mention of a Tardis is not a surprise, as the programme is well-known for its choice of background music that regularly has viewers chuckling - find out more about that here.
But it's the small addition to the house, bizarrely hiding in an alcove cupboard, that grabs Martin's attention at this house and has him giggling, saying: "Oh that tickles me! The world's smallest radiator."
Even local property developer Rhian, who bought the home for £101k, didn't see it. Before buying, she gave the house a thorough look - she spotted damp, missing roof tiles, wall ties that needed attention, and a side pathway that was laid above the damp proof cause, but she totally missed the hobbit sized radiator.
She says: "Oh, I never noticed that. It is pretty small, there's a couple of quirky features that we need to find out about." Martin answers, "That's not surprising really is it, because it's so small!"
But back to the serious business of property transformations and Rhian's plans for this house, her tenth development project.
The former social worker, who is now following her property passion, estimates a three-month timescale and a budget of between £14,000 and £19,000 to bring this tired semi-detached house back to life, and that includes removing the teeny, tiny rad.
The programme returns in four months and the house has had a complete overhaul ranging from repairs to the roof, re-routing some guttering and tackling wall tie failure with the aim of eradicating the damp issue that was appearing in some rooms.
The house has had a complete overhaul inside too, including rewiring, plastering throughout, flooring, decorating, and a new kitchen.
There's been a complete replumb too including a new ground floor shower room, a new bathroom upstairs and new heating including the demise of the radiator that hopefully Rhian has given to Martin as a present.
The budget went over the estimate to £24,100 due to Rhian replacing 'about 90%' of the windows plus the French doors out to the garden patio that she hadn't intended on updating, and the removal of a vast amount of garden waste.
A local estate agent arrives at the front door to deliver some fantastic rental news for Rhian, an estimate of between £850 to £900 per calendar month that would produce a rental yield of about 8.7%, and that has her potentially rethinking her plans to sell.
The resale value this agent suggests does not have such a welcome response though, an estimate of £170,000 launching it onto the market as offers in excess of £155,000.
But Rhian is not new to the property renovation game now and has already had her own agent come out to view the newly spruced up abode.
Her agent gives her a resale value of £180,000 which, if achieved, would produce a pre-tax profit of around £55k - a very healthy profit that can buy a larger radiator for the rear reception room.
But when asked Rhian has some advice for would-be property developers and it doesn't focus on the size of the radiators.
She says: "If you've got passion and you've got determination, go for it. But get some education, don't go into it blind, be really careful about your numbers and, as long as you are cautious and sensible, I think property is always going to be a good asset."
