1Executive Summary
This report sets out our estimate for the construction of a single storey rear extension at 14 Oakfield Road, London SW00 0AA, providing approximately 42 m² additional floor area. It has been prepared for Mr & Mrs Sample on the basis of the drawings and information listed in Section 2.
The net total of £128,788.03 includes overheads and profit at 8% and a construction contingency at 5%. With VAT at 20%, the total is £154,545.64.
The estimate carries PC and provisional sums totalling £27,414.00 for items not yet finally selected (Section 7). We have also set out value engineering options in Section 8 that could reduce the cost by up to £7,150.00 if adopted.
This is an estimate rather than a fixed-price tender. It should be read together with the assumptions, exclusions and qualifications, which define exactly what is and is not included. All dimensions must be verified on site before ordering or starting work.
