A. Uric acid is a chemical breakdown product of metabolism. The liver produces uric acid by breaking down other chemicals, called purines. Uric acid is normally found in the blood in low concentrations. Some people are prone to high uric acid levels, which can sometimes lead to gout, kidney stones, or kidney damage..

Extensions are more expensive: RICS gives a guide cost of between Â£1,260 and Â£1,680 per square metre for an extension with plastered finish. So a 20-square metre single-storey extension will range from Â£25,200 to Â£33,600 â before you've put down flooring or installed a kitchen.s a rough guide, the Royal Institution of Chartered Surveyors (RICS) suggests that the cost of a loft conversion for a plaster-finished shell, excluding decoration and floor finishes, is Â£660 to Â£900 per square metre including VAT.
As a rule of thumb you can add 50% extra to the build cost of a single storey extension. So, Â£24,000 +50% = Â£36,000. + Add on 10-15% for professional fees (architect, planning application, building regs, structural engineer).+ VAT.ou may have heard that the rule of thumb is Â£1,000 per m2. However, this figure has been bandied about for rather a long time now! From experience, Â£1,200 per m2 is a now a more realistic estimate for a house extension cost in 2015 and reflects price increases over the last few years.
