Updated: Apr 24, 2023

Two storey side home extension architectural design services in Welwyn Garden City, AL7 Hertfordshire, United Kingdom. The scheme included adding a two storey side home extension to the side of the property to accommodate extra space for the kitchen and new utility to the rear of the property with a study/office to the front of the property with a front window.


On the first floor a extra large master bedroom with large ensuite and walk in wardrobe space and windows to the front of the property, rear and side.


The roof is to match existing gable and ridge. The true benefit of this property is all the additional spaces to truly enjoy making this property almost double in size.

A full set of Building Regulation drawings will include proposed plans, elevations, cross sections, details, full specification detailing construction methods, workmanship standards and quality of materials.

Structural Calculation Drawings - When all approvals have come in the structural process will start, this is an important part of the design as that will present a clear scope of how to achieve the construction of the project, The project will not be able to start without the structural drawings.
