Below you will find the full catalogue of designs for Terrace Type 1, including existing drawings of the property and all available extension options across Back, Side, Wrap Around and Loft categories.
Each design can be accessed in two ways - purchased outright as a one-off download, or downloaded as part of your subscription (aimed at Architects, Property Developers & Contractors). Simply select your preferred option beneath each drawing. If you hold a subscription and have remaining downloads, enter your plan details and the drawing will be sent directly to your email.
Any amendments to the drawings can be requested after access is granted, subject to your plan or purchase terms.
