A revamped B&Q store near Birmingham has been earmarked as the benchmark for a potential £200 million n ational makeover programme for the ailing chain.
Owner Kingfisher is considering whether to roll out a raft of improvements at 110 of its biggest operations.
A spokesman said the group would trial the new look at its revamped Wednesbury store which is due to open this week.
Similar projects are also under way in Gloucester, Milton Keynes and Luton.
The spokesman said: "We will be looking at the progress of those outlets in making any f uture decisions on refurbishments."
The proposed three-year programme in the UK would involve stores of around 100,000 sq ft and could cost a total of £200 million to complete. Each store is likely to cost between £1.5 million and £2 million to complete, King-fisher says.
The Wednesbury store - at Park Lane - will employ a further 60 people taking the headcount to around 300.
A B&Q spokesman said: "The idea is to get more into home improvement rather than just providing a DIY warehouse-based service.
" To that end, the Wednesbury store will have 40 per cent more space for show-rooms as well as offering the public a 25 strong team giving free advice on a range of areas from plumbing to fitting a floor."
It will also provide free clubs aimed at allowing people to make friends while gaining new skills.
The store - which was revamped while remaining open - will be officially opened on Thursday by Olympic badminton silver medallist Gail Emms. It boasts a floorspace of 140,000 sq ft - the same as the original operation but with the internal design radically altered.
The moves emerged two months after Kingfisher announced profits dived 70 per cent in the UK because of a challenging market and the impact of promotional activity.
Analysts expect a slight improvement in trading figures when the company reports sales for the half-year stage later this week.
Investec analyst Matthew McEachran said he expected a 4.4 per cent like-for-like decline for B&Q in the 11 weeks to July 15, despite a weak comparative of 6.4 per cent a year earlier.
He added: "We believe the World Cup and hot weather will have detracted from any underlying improvements to performance."
The new sites devote more space to products within a showroom effect.
A Kingfisher spokesman said: "Consumers are increasingly more interested in the finished look they can get, rather than the process of getting there."
Space allocated to show-room products is likely to increase to around a quarter of the store.
