BARTON VISITOR’S CENTRE
Located Located along the M62 .
Project Brief
Located north east of the Observatory the Barton Visitor’s is located on what used to be part of chat moss and creates a link between port salford master plan, Off the Beaten Track Masterplan & the Cadished/Little Woolden Bird Hide Conservationist Facility.
The Barton Visitor’s Centre provides a means to create a communal space for mainly plan spotters and individulas willing to become piolts whilst preseving site hertiage through materiality selection such as brick.

Why SIPs and glulam and Brick?
Structural insulated panels as main structural componet.
• The use of non flamed materialsresults into very limited contribution to fire that may lead to fire spread and little no smaoke production.
• The use of oriented strand boards in SIPs render them highly resistant to water.
• 142mm of adeqaute insulation results into little to no heat loss gain within the structure.
Glulam
• Light in nature and strong under compression from external forces.
• Highly resistant to fire (burn off rate 0.7mm/min) most espically with the addition of fire protective finishes such as Zeroflame Fire Retardant Paint hence waterproffing it as well.
Brick
• The availablity of locally sourced bricks onsite helps reduce the cost of material purchase as well as enables structural itergration into site context with existing buildings.
