Floor to ceiling windows cost from £1,050 per m² for a structural glass internal wall, or up to £3,825 for bifold doors.
These costs are for materials only - you'll also need to pay for labour for the installation.
Structural glass gives you an uninterrupted wall of glass, ideal if you want an unbroken view. See our structural glass wall cost guide for a full breakdown.
Bifold doors, meanwhile, can be opened and closed like patio doors, and can be easier to install - though they're only an option if the window opens onto a garden or outdoor space. Check our guide on the cost to install bifold doors for more detail.
Cost of installing floor to ceiling windows
Labour typically costs from £600 on top of materials, depending on the size and complexity of your project.
Additional costs to budget for
On top of the window itself, budget for:
Structural engineer fees to sign off the design (£90 to £125 per hour)
Building regulations costs for the submission (£100 to £125)
A building regulations inspection (around £300)
These fees apply whether you choose structural glass or bifold doors, so factor them into your total budget from the start.
