This is a project for a single storey side-return extension and internal alterations and modifications for a two storey semi – detached house in Guildford.
The ground floor is formed in 150mm thick reinforced concrete ground bearing slab reinforced with one layer of A252 mesh in top throughout.
The foundations are 600mm wide concentric & eccentric mass concrete trench footings with minimum depth of 1000mm from ground level.
For the opening between the existing house and proposed rear extension we have proposed steel beam bearing on two piers built in engineering bricks 75 N/mm2.
The roof is formed in roof rafters bearing on a timber plate on one side and the steel beam B3 and the proposed brick wall on the other side.
The structural drawings and calculations were submitted and approved by Building Control and the building works were finished in three months time.
