Types of House Extension

Rear Extension

A popular choice for homeowners looking to enlarge their kitchen, add dining or family areas, or incorporate extra bedrooms or bathrooms. These extensions are custom-designed and constructed to seamlessly blend with the existing architecture while complying with building regulations. Rear extensions offer a practical and versatile solution for maximizing living space and improving property value without the need for major structural changes or relocation.

Side Extension

These are built along the side boundary of the property and are commonly used to enlarge existing rooms or add new spaces like home offices or utility rooms. Side extensions maximize a property’s footprint, increase living area, and enhance property value. Like rear extensions, they’re custom-designed, comply with regulations, and vary in size and complexity based on available space and homeowner preferences.

Single Storey Extension

A single-storey extension can be used to enlarge existing rooms, such as kitchens, dining areas, or living rooms, or to add entirely new spaces like home offices, playrooms, or guest bedrooms. By extending outwards rather than upwards, single-storey extensions can often be more cost-effective and less disruptive than multi-storey alternatives.

Double Storey Extension

This involves adding two levels of additional living space to an existing property, by extending upwards, to add extra bedrooms, bathrooms, or living areas. This type of extension is ideal for expanding growing families or adding luxurious features to your home. As an experienced construction firm, we specialize in designing and constructing seamless double storey extensions that seamlessly blend with the existing structure of your property.

Wrap Around Extension

Here we would extend a property on two or more sides, creating additional living space that “wraps around” the side and rear existing structure. This type of extension is an optimal way to expand both the width and depth of your home simultaneously and add considerable floor area.
