Täby is largely made up of well-kept 1960s-70s villa areas in Näsbypark, Gribbylund and Skarpäng, with high owner-occupancy and generous renovation budgets. Expectations on finish are high, which shows in material choices and therefore in the quotes. Plots are roomy and easy to reach with machinery, so drainage and roof work avoid the surcharges tight sites bring. Demand for trades across the north-east sector is strong, pushing prices above the national average.
