Building Regulation Drawings Side Return Extension

What is a side return extension?

A side return is a type of home addition that uses the narrow strip of empty land on the side of a building, which is common in Victorian or terraced homes, making it a simple side extension option. People often call this area the “side return,” and it runs along the wall of the house next to the kitchen, providing an opportunity for additional space. People can make their kitchen, dining room, or open-plan living space bigger on the first floor by adding on to this area. 

Side returns are typically used on Victorian terraced houses to maximize space by creating a single-story side extension, often for a kitchen-dining or reception room, while maintaining access to the garden.

Do I Need Building Regulation Drawings ?

Yes, absolutely. Any wraparound extension requires building regulations approval, which means you need proper building regulation drawings to submit with your application.

Building Regulations apply to almost all building work involving structural changes. Your house extension creates habitable living space through the process of building a side extension combined with a rear extension. The drawings prove you comply with regulations, guide your builder during construction, and protect your property value. The extension is an exciting opportunity to transform your home, but only when done legally.

How are energy efficiency and insulation addressed in building projects?

Compliance with current temperature standards for side return expansions is essential for building drawings.

Our plans detail the necessary insulation levels for roofs, walls, and floors. We also address thermal bridging and airflow management to prevent condensation, which is vital for single-storey side extensions that require neighbour consultation. This approach not only facilitates regulatory approval but also enhances occupant comfort and reduces energy expenses over time.

Side Return Extension Overview

Home extensions allow creating a side extension, often a single storey side or two-storey side, to achieve a spacious kitchen extension and better use of garden space with readily available materials. Side return extensions are tricky and may need regs, building approval, or apply for planning permission under permitted development and pd rights, so proper design and build, structural design, extension plans, and rooflights are essential before you start building.
