WHAT we OFFER
Why Choose a House Extension Instead of Moving?
A house extension allows you to:
- Increase the overall value of the property
- Gain extra living space without leaving your area
- Avoid moving costs and stamp duty
- Customise your home to suit your family
Many homeowners reach a point where their current home no longer fits their lifestyle. Rather than moving, extending can often be the smarter option.
For growing families or homeowners wanting open-plan living, an extension can completely transform how a home feels and functions.
How it works
Types of House Extensions We Build
Every property is different, which is why extensions should always be tailored to the home and the homeowner’s goals.
Rear Extensions
Rear extensions are ideal for creating open-plan kitchens, dining areas, or larger living spaces that flow into the garden.
Side Extensions
Side extensions work well for adding utility rooms, additional living space, or expanding existing rooms where side access allows.
Wraparound Extensions
A combination of rear and side extensions, wraparounds maximise space and dramatically change the layout of a home.
Double-Storey Extensions
For those needing significant extra space, double-storey extensions provide additional bedrooms, bathrooms, or home offices.
The Importance of Doing an Extension Properly
A house extension is a major structural project, and poor planning or rushed work can lead to costly problems later on. A properly built extension should integrate seamlessly with the existing structure, meet all building regulations and structural standards, remain energy efficient and weather-tight, and match the style and finish of the original property.
At RMK Ltd, every extension is built with long-term durability in mind, focusing on quality construction rather than short-term fixes.

Frequently Asked Questions
Do I Need Planning Permission for a House Extension?
Not all house extensions require planning permission. Some fall under permitted development rights, depending on the size, height, and location of the extension. However, factors such as conservation areas, listed buildings, or larger extensions may require approval. It’s always best to check before starting, and a professional builder can advise early to avoid delays.
How Much Does a House Extension Cost in Glasgow?
The cost of a house extension varies depending on size, layout, ground conditions, and the level of finish required. Structural work, foundations, and services all affect the final price. Because every property is different, extensions should always be priced following a site visit and a clear scope of works rather than using fixed online estimates.
How Long Does It Take to Build a House Extension?
Most house extensions take several weeks to a few months to complete, depending on complexity and scale. Single-storey extensions are typically quicker than double-storey projects, while weather conditions and material availability can also affect timelines. Proper planning helps keep the build on schedule.
Will a House Extension Add Value to My Property?
A well-designed and professionally built extension can significantly increase a property’s value, especially when it improves layout, adds usable living space, or creates open-plan areas. Extensions are often seen as one of the best home improvements for long-term value when completed to a high standard.
