Annexes and Ancillary Buildings

We offer a turnkey service, which includes groundworks^, full structural calculations, standard planning application^^, installation and finishing, based on one of our four Annexe models.

We can offer this as an additional service through our in-house RIBA architects.

Most Annexes do need planning permission and our experienced team will assist with this.

Our payment terms span three stages:

Stage 1: 5% of total order upon client acceptance of estimated price, when we will prepare working drawings for client approval and book a provisional production date in our workshops.

Stage 2: 30% of total order upon client approval of working drawings, when we will instruct the Structural Engineer to prepare structural drawings and calculations, update the estimate and drawings if appropriate and confirm a production date in our workshops.

Stage 3: 60% of total order 7 days prior to installation of the Annexe.

Stage 4: 5% of total order 4 weeks after installation.
