        1. Dylan Foster –

          Went with a small skylight and it’s incredible how it’s changed the dynamics of our living space.

        2. Boris Grants –

          Our quaint cottage now feels so much brighter thanks to the new pitched skylight from Kings View. The 400 x 400 size was just perfect for our cozy space.

        3. Conor O’Neill, Belfast –

          Opted for a small 400×400 mm skylight in our bathroom renovation. It provides just the right amount of light without compromising privacy. The installation team was courteous and tidy—excellent service all around.

        4. Kieran Doyle –

          Opted for a small 400×400 mm skylight in the tiny home office. It’s just the right amount of light for the space without any compromise on privacy. Plus, the energy efficiency is a bonus!

        5. Fiona Gallagher –

          We installed a pitched roof skylight in our townhouse, and it’s been a great update for our attic studio. The natural light it lets in is just astounding. Couldn’t be happier with the quality and the swift delivery!

        6. Emily Clarke –

          It’s a decent skylight. Fits well in our living room.
