Loft Extensions - The Build Process

The building stage is without doubt the most exciting part of loft extensions. We have already taken the strain out of the surveying and planning stages by obtaining all the necessary permits and permissions on your behalf.

Your house is about to be transformed with the addition of a room or rooms by our expert tradesmen, skilled in all areas of construction to a highest standards.

Your project manager will contact you two or three weeks prior to the start date to arrange a meeting. Any questions you may have regarding the plans, contract or building process will be answered at this time. We will also clarify the exact position and access for the scaffolding and materials etc, confirm the type of handrails, stair parts and skirting boards if they are to be matched.

The scaffolding will be erected either on or prior to the commencement date. On the commencement date the loft team will be on site to take the delivery of most of the materials required to carry out the conversion. If it is needed, a crane will also be on site to lift the materials onto the scaffolding for access.

The exact procedure for building the loft conversion can be discussed between yourself and your project manager, however a typical building procedure is as detailed below.

  • Steel beams and supporting floor beams are installed.
  • Floor joists and floor boards are installed.
  • Dormer window constructed and roof lights fitted.
  • The loft room is insulated.
  • Internal partitions are built and plasterboard fitted.
  • The ceiling is cut out and the staircase is fitted.

All of the above work is carried out by the loft team. In addition to this the plumber and electrician will attend the site to install the necessary pipes and cables. The flat roof of any dormer window constructed will be felted by a roofing contractor at the earliest opportunity. The building inspector will make two of his three visits during this time to inspect the floor detail and the roof structure with the insulation fitted.

After the staircase is fitted the loft team will leave the site and the conversion will be fully plastered. Typically a conversion will take up to five days to dry out. During the drying time no other work will can be carried out, as any vibration might damage the plastering unless it has completely dried out.
