Building it well and choosing strong materials also helps it stay in good shape. Check your buildings regularly and fix any problems right away to help it last.

Why Choose a 16×16 Garden Room?

These buildings have become more popular in recent years for several reasons:

Working from home
More and more people are working from home full-time or part-time, so they need a dedicated workspace. A garden office provides a quiet, comfortable space away from the hustle and bustle of the heart of the house while also freeing up room indoors.

Versatile options
These units are versatile and flexible. They can be used as offices, teenage hangouts and dens, garden bars, art and design studios, home gyms, dance and yoga studios or tranquil retreats designed to induce calm and relaxation.

Provides an alternative to moving
Studies show that Brits are increasingly likely to renovate and update their homes rather than move house. According to a recent survey by the Royal Institution of Chartered Surveyors, 79% of UK homeowners prefer renovation over moving to a new house. Adding a room in the garden is a brilliant way to increase living space and cater to modern lifestyles for those who don’t want to move.
