Loft conversions
Loft conversions, priced line by line.
Turn unused roof space into a bedroom, bathroom or office. See the cost drivers before you commit.
What a loft conversion involves
The roof decides the options.
What is possible depends on your roof structure, the head height you have and what planning allows. We look at the property and talk through the options that suit it, including dormer and hip-to-gable designs where they apply.
Your quotation sets out exactly what is included and what is not, line by line.
