About single storey extension in Dundee
Dundee is a medium town of around 149,000 in Dundee. The housing is mostly Victorian tenements, sandstone terraces and 20th-century estates typical of Scottish and Welsh urban centres. That matters: older properties usually mean more pipework, rewiring and retrofit surprises, while newer builds in districts like DD1, DD2 tend to be quicker jobs with standardised fittings. Local trade prices sit below the UK average. Lower contractor overheads and shorter distances across Dundee do most of the work.
Scottish pricing runs from Edinburgh (above average) to the Highlands (variable, often with long lead times). The trade bodies are different here — SELECT for sparkies, SNIPEF for plumbers, and the regulatory framework is Building Standards rather than Building Regulations. Doesn't usually slow jobs down, but the paperwork changes.
Building jobs are labour-heavy, and materials have moved fast — brick, timber, steel, insulation and board are all 20 to 40 percent up on pre-2022. FMB and TrustMark are your best signposts for a proper builder. On anything bigger than a loft conversion, get a Building Control officer involved from day one; fixing non-compliance later costs a fortune.
