Jobs would be created as part of plans to create a ‘shopping village’ and new outdoor plant area at Dobbies flagship store in Lasswade.
The plans, which have been submitted to Midlothian Council, aim to create “the best plant destination in the country” according to the company.
Stuart Wright, Property Director at Dobbies said: “We have spent considerable time shaping these plans to make sure they are absolutely right for our flagship store.
“We’re certain our customers will be delighted with our planned improvements in making Dobbies, Lasswade, a truly showpiece garden centre destination.
“The developments, of which the new structures will be entirely constructed from timber – will offer an improved shopping experience for our customers including greater choice and inspiration for their own gardens, in an attractive shopping environment.”
The plans also include building a new shopping village in the centre’s existing outdoor space.
This would be occupied by leading retail brands which compliment the range of goods and services offered by Dobbies.
The company’s UK headquarters have been located adjacent to the Lasswade garden centre since the store was originally built in 1975.
Dobbies store at Lasswade currently offers more than 10,000 plants, shrubs and trees and includes extensive outdoor areas and a specialist aquatics department.
It also houses a Farm Foodhall offering locally-grown produce from Edinburgh and the Lothians, as well as the largest restaurant in the UK, according to the company.
