Plans for a £1.2m welcome block have been announced at Kiplin Hall and Gardens, near Scorton.
The charity which owns the historic house plans to build a new welcome block and improve car parking.
The facility will include a new cafe, terrace seating with views across the lake, an exhibition space, and accessible toilets.
The project is expected to cost in the region of £1.2million and will be paid for by a combination of funding streams, including donations.
Kiplin Hall and Gardens is an independent charity that relies on ticket sales for income and will be seeking more funding for this project in the coming months.
Bauman Lyons Architects Ltd, a Leeds-based firm, have been appointed to design the welcome block in consultation with staff, volunteers, and visitors.
Guy Smith, director of Bauman Lyons Architects Ltd, said: “We are delighted to be playing a role in making Kiplin Hall and Gardens more accessible and known, preserving its heritage for new generations.”
Director of Kiplin Hall and Gardens, James Etherington, said: “Kiplin Hall and Gardens is known and loved for its warm welcome and tranquil setting.
“As the visitor attraction grows in popularity we are keen to retain this reputation and experience for visitors, while welcoming more people to share in the adventures and everyday lives undertaken by the people who lived and worked here.
“A new welcome block will make access to all that Kiplin has to offer easier for everyone.
“It will also free up more space in museum for historic displays.”
Chair of trustees for Kiplin Hall and Gardens, Lindsay Osario, added: “In the light of the covid pandemic we are also working hard to develop opportunities for visitors to explore the history of the house from our invaluable outdoor spaces. Some of these creative and exciting new gardens will be opening in 2022, while the building project will take a couple of years to complete.
“As Kiplin Hall approaches it’s 400th anniversary celebration in 2025 we will be in a position to celebrate the achievements of the past and look forward to the future.”
Kiplin Hall and Gardens is open six days a week, closed on Thursdays.
The historic house museum displays the possessions, art and furniture of the four families who owned the hall over 400 years.
The 90 aces of grounds include formal gardens, lakeside walks, woodland paths and open parkland with grazing sheep.
