A substantial redevelopment of an existing three storey Victorian property, comprising of a rear extension, loft conversion and new basement.
The new mansard roof was constructed using timer, with steels used to support it.
The loft was constructed using timber with a timber floor and steels used for supports.
Ground floor: The extension was designed with masonry cavity walls and a beam and block floor. A portal frame was used for lateral stability to the rear of the property.
Structurally the new basement development was the most challenging. The basement was a new concrete box constructed of retaining walls and slab, achieving an open space of 100m². A methodical approach to place the new structure with minimum disturbance to the main existing building was the main concern. Croft Structural Engineers designed and proposed the temporary work solutions required, allowing the safe excavation and casting of the new basement, minimizing the cracking of the masonry above.
