One of the best parts of our work at Reltic Extend is seeing the look on a homeowner’s face when their project is complete. The moment they walk into their new space, the transformation feels magical – almost like moving into a brand-new home without leaving the one they love.
In this article, we’ll explore real-life extension possibilities, looking at how a simple idea can completely reshape a property. From compact kitchen upgrades to large wraparound builds, these “before and after” transformations show what’s truly possible for your home.
Why Extensions Are More Than Just Extra Space
Adding an extension isn’t only about square metres. It’s about:
Lifestyle upgrades – open-plan kitchens for family time or entertaining.
Property value – increasing your home’s market worth.
Practicality – making space for home offices, playrooms, or storage.
Aesthetics – turning dated layouts into modern, stylish living areas.
A well-planned extension can change the way you live every single day.

Before & After: The Classic Rear Extension
For many homeowners, the dream starts with a Rear Extension. Typically built out into the garden, it creates a light-filled, open-plan living area.
Before: A cramped kitchen with little natural light.
After: A stunning glass-fronted extension with bi-fold doors opening onto the garden.
Why it works: Rear extensions connect indoors with outdoors, adding lifestyle value and making small homes feel double their size.
Before & After: The Kitchen Extension That Became the Heart of the Home
The kitchen is more than a place to cook – it’s where families gather. A Kitchen Extension is one of the most transformative projects we deliver.
Before: A narrow galley kitchen, cut off from the dining room.
After: A wide, open kitchen-diner with a skylight and island, perfect for cooking and entertaining.
Why it works: Kitchen extensions bring light, space, and function together, turning mealtimes into a joyful experience.
Before & After: Maximising Narrow Spaces With Side Extensions
Many London homes – especially terraced ones – have underused side passages. With a Side Extension, that wasted strip of land becomes valuable living space.
Before: A dark, narrow kitchen with limited movement.
After: A bright, spacious kitchen-diner with skylights and seamless flow.
Why it works: Side extensions unlock hidden potential, making compact homes feel dramatically bigger.
Before & After: Wraparound Extensions That Redefine Homes
A Wraparound Extension combines a rear and side return extension to form one continuous space.
Before: A separate kitchen, dining room, and living room – all disconnected.
After: A single, flowing open-plan area with garden access, light, and multifunctional zones.
Why it works: Wraparounds completely reshape the way a house works, adding both value and lifestyle benefits.
Before & After: The Double Storey Upgrade
When families outgrow their homes, moving isn’t the only option. A Double Storey Extension creates space both upstairs and downstairs.
Before: A three-bedroom home with no guest space or office.
After: A larger living area, plus new bedrooms and bathrooms upstairs.
Why it works: Double storey extensions offer incredible value per square metre and future-proof your home.
Before & After: Regional Inspirations Across London & Surrey
Every area has its own character, and transformations adapt accordingly:
North London – side return extensions maximise Victorian terraced houses.
South London – rear and wraparound projects create bright family hubs.
East London – compact kitchen extensions add value to smaller homes.
West London – premium double storey projects transform period homes.
Surrey – larger plots allow generous wraparounds and open-plan designs.
Design Principles Behind Every Transformation
Great transformations don’t happen by chance. They follow key design rules:
Respecting the character of the home – old and new blending seamlessly.
Prioritising natural light – skylights, bi-folds, and large windows.
Optimising flow – layouts that support family life.
Choosing smart materials – durable and stylish.
Planning carefully – to avoid delays and hidden costs.

Avoiding the “Bad Before & After”
Sadly, not all extensions are transformative in a good way. Mistakes to avoid include:
Poor integration with the existing house,
Using cheap materials that don’t last,
Overlooking planning rules,
Ignoring practical details like storage.
Our Planning page explains how to avoid costly setbacks before work begins.
The Emotional Impact of Transformation
Homeowners often tell us that after their extension:
“The house finally feels like ours.”
“We use every part of the home now.”
“It feels like moving into a new property without leaving the neighbourhood.”
An extension doesn’t just change your home – it changes your life.
