    Dual Entrance in Modern Style

    A great feature of the Tessa is the dual entrance doors which allow accessing the summerhouse easy and stress-free. You can enter the summerhouse through the double doors, located on the front of the summerhouse or the side door if you prefer.

    During hot, summer months you can open all the doors to keep a blissful airflow throughout the build. Or, you can keep the central doors shut to keep the modern look to the front of the Tessa and access the summerhouse from the side. These multi-access doors provide you with great access to the summerhouse.

    Relax with Stunning Views of your Garden

    Relax with Stunning Views of your Garden

    This fantastic summerhouse provides you with stunning views of your garden. The elegant and stylish windows flow round from the side to the front of the build which looks truly spectacular from outside and inside the building.

    With the addition of the Tessa, you can relax with views of your garden all year round. This summerhouse makes a fantastic space to unwind with your friends and family, come rain or shine!

    Strong T&G Build and Construction

    The Tessa is constructed using our incredibly popular tongue and groove technique. The T&G boards provide the summerhouse with a strong and sturdy build. The panels are all pre-cut to length and the interlocking style of this construction means each board will hold the previous board securely in place.

    As well as providing a strong build, the T&G construction also gives the summerhouse great protection from the elements. As the panels interlock together, rain runs off the side of the building, ultimately preventing any long term rot issues.

    Modern Door and Window Design

    Modern Door and Window Design

    The modern windows and doors are just some of the excellent features of the Tessa. The summerhouse is provided with long windows which maximise the natural light that streams into the building, keeping the summerhouse feeling light and airy and a great space to spend time in.

    The doors are designed to match the style of the elegant windows. So, once closed, the unit looks modern and stylish. As well as this, the large windows and doors mean you have great views to look out on. Sit back, relax and enjoy the wonderful views of your garden.

    Position the Doors on the Eaves to Suit your Needs

    A great feature of the Tessa is the double doors which can be positioned anywhere along the eaves, on the front of the build to suit your personal needs. Position the doors in the center or anywhere along the front of the build. Customise how you enter your Tessa summerhouse!

    The holly door gable at the side of the build is fixed in place with a window on either side of the door. This creates a continuous view around the garden and a stunning look to the exterior of the build.
