The Inn Collection Group has secured funding from OakNorth to open its eighth site and extend three more.
The North-East based group, established in 2006, is expected to open the 30-bedroom Amble Inn in Northumberland, in October.
As well as the new opening 13 bedrooms have been added to the annex of the Bamburgh Castle Inn and the Seaton Lane Inn (pictures) has been refurbished.
There are also plans for 29 new rooms to be added to the Kingslodge Inn in Durham city centre.
The work will bring the number of rooms under its portfolio to almost 300 by 2020.
The Inn Collection Group's managing director, Sean Donkin, said: "Over the last half decade, we've embarked on a ‘buy and build' growth strategy that has seen us become one of the largest private providers of accommodation in North East England.
"Over the next three years, we will continue to develop and seek out new premises, focusing on sites that fit with our philosophy and the continual evolution of our group, offering high-quality accommodation at value for money prices. Raising funds from OakNorth will pave the way for us to drive these growth plans and focus on the immediate expansion of our pubs with rooms model."
Stuart Blair, debt finance director at OakNorth, said: "The UK's hotel industry has seen annual growth of 3% for the last five years, boosted by major events such as the London Olympics, the Royal Wedding, and the Rugby World Cup. The Great Exhibition of the North which is currently underway is expected to give the region's tourism a further boost, attracting approximately three million people and one million from across the UK.
