What types of loft conversion do you offer?
We design all types including Dormer conversions (creating additional headroom and floor space), Mansard conversions (ideal for terraced homes), and Hip-to-Gable conversions (perfect for detached or end-of-terrace properties). We'll recommend the best option for your home.
Do I need planning permission for a loft conversion?
Many loft conversions fall under Permitted Development rights and don't require planning permission. However, this depends on your property type, location, and the scale of works. We'll assess this at your free consultation and handle any applications needed.
How much does a loft conversion cost?
Costs depend on the type of conversion and specification. We provide transparent guidance at your consultation and can design to suit a range of budgets. A loft conversion is typically more cost-effective than a ground-floor extension per square metre.
How long does a loft conversion take?
The design and planning phase typically takes 2 to 3 months, with the build taking around 6 to 10 weeks depending on complexity. We'll give you a clear timeline for your specific project.
Is my loft suitable for conversion?
Most lofts can be converted, but key factors include head height (ideally 2.2m+ at the ridge), roof pitch, and available footprint. Our free survey will determine exactly what's possible with your property.
Will a loft conversion add value to my home?
Yes. A loft conversion is one of the highest-return home improvements. On average, a well-designed loft conversion adds 20 to 25% to a property's value, often far exceeding the cost of the work.
