Notcutts will celebrate the opening of its redeveloped Pembury garden centre, near Tunbridge Wells, on April 11.
The 25,000sq ft outlet is built on the site of the old one and has been designed to harness the natural surroundings of the site and to reflect the company's horticultural heritage.
The new centre is eco-friendly, using solar panels to capture sunlight, movement sensor taps to save water and low energy lighting. The store also has increased disabled access.
New to the centre is a 190-seat restaurant called The Kitchen. Meals served will be cooked using local produce. Other new features include a canopy-covered planteria area, a shop for local butcher Ian Chatfield, a children's play area and a pet department.
Premises director Michael Cole said: "We're absolutely delighted with the new centre, so are thrilled to open its doors to our customers.
"Whilst we've still been trading at the temporary store throughout the re-build, it's been an anticipating wait and seeing the final centre in all its glory is very exciting indeed. We hope our customers will love it as much as we do."
The great-granddaughter of the founder of Notcutts, Caroline Notcutt, will cut the ribbon at the opening next week.
