Loft Conversion - Build Costs
Below are a few examples of typical loft conversions together with the approximate cost a builder will charge. Much will depend on your desired specification but we hope this provides a useful starting point for budgeting.
 |
Box Dormer - £28K-£35K Approx.
A Flat-roofed rear extension which is designed to maximize headroom and floor area, it can be either full roof width or stepped back from the eaves. |
 |
Mansard Dormer £34K-£40K Approx.
This angled roof extension has the Party Wall built up in brickwork and a 72 degree sloping rear wall incorporating a number of small dormer windows. |
 |
Hip to Gable £32K-£40K Approx.
The typical pyramid style 1930's roof is removed and a new vertical gable wall is constructed in block or tile hung allowing headroom for stairs. It is often combined with a rear box dormer. The juliet balcony illustrated is also often specified. |
 |
L-Shaped Dormer £35K-£44K Approx.
This is often considered as the best way to extend a mid terrace period proporty to maximize space. The box dormer or mansard is complemented with an additional extension over the rear roof. Ideal for a master-suite and a separate bathroom or Study Room. In most cases this generally falls under Permitted Development. |
"How much does a loft conversion cost?" or "How much will it cost to convert my loft" are two of the most common questions we get asked. The answer can depend alot on alot of factors such as are you putting a bathroom in your loft conversion and if so what fixtures and fittings will you be installing? Also "What does a loft conversion cost in Oxford?" will get a different answer to "What will a loft conversion cost in Twickenham or Richmond?". But the above examples are designed to give you an understanding of what you might expect and has been averaged to cover regional variation between the Oxfordshire, Buckinghamshire, Berkshire area and London.
