Overall what makes our products stand out amongst the rest is the simplicity of our customisation and uniqueness. No building is the same, and with our buildings, you can customise the design and make your building feel like your own. As opposed to structures that arrive flat-packed or one building model, we offer the option of design customisation, and our professional installer team installs every single building.
Feedback from our clients often states that our construction is one of the least intrusive forms of a home expansion. The disruption to daily life tends to be minimal as all of the installation takes place in the garden, especially if you have easy garden access. With a very swift installation window, your space will be ready to go within no time, and you will be left with your permanent retreat.

Do I Need Planning Permission?
Most of our projects do not require planning permission as the design our buildings class them as outbuildings that fall within your permitted development rights. However, in some cases, it may be necessary. In the case of this, our team handle the entire process and will keep customers updated each and every step of the way.
