Pub chain JD Wetherspoon said it plans to open 30 new pubs and create 1,200 jobs next year.
The expansion - part of investment in its estate worth £60 million - comes as the group prepares for the introduction of a smoking ban in England and Wales.
Chief executive John Hutson said he hoped the ban, which is already in place at a number of Wetherspoon sites, would result in more people visiting pubs in the long-term.
Mr Hutson added: "Our non-smoking pubs have proven very popular and this has given us the impetus to open more pubs in 2007."
Wetherspoon opened 12 new outlets in 2006, but will invest more than £35 million in 30 sites next year, including at Sheffield, Bishop Auckland, St Austell, Hertford and Devizes, Wiltshire. It currently has 662 pubs.
In addition, the company plans to invest a further £25 million on its existing outlets, including the creation of outside smoking areas.
Wetherspoon has slowed its annual opening programme in recent years while it assessed the likely impact of the smoking ban.
Around 100 sites are already smoke-free, including a mixture of new and converted outlets in England and Wales, as well as 39 pubs in Scotland following the introduction of regulations there last spring.
Wetherspoon said in November that quarterly like-for-like sales were up 5.2 per cent in Scotland, although the biggest test for sales figures will come this winter as smokers will be forced to light up outside.
In non-smoking pubs in England and Wales, sales rose 11.8 per cent in the quarter, with the figure still up by 2.2 per cent on two years ago when smoking was permitted.
Analysts said at the time that the performance of non-smoking pubs - both north and south of the border - had been better than expected and a "clear positive" for the company and the rest of the pubs sector.
The ban in England will be introduced on July 1.
