House Extension Types We Can Build For You
Choosing the right loft conversion depends on your home's structure, budget, and what you want to achieve with the space. At VNP Constructions, we offer four main types of loft conversions, each with its own benefits. To decide which is best for you, consider these three key factors:
- Available space and roof structure – The existing shape and height of your loft will determine what type of conversion is possible.
- Budget and complexity – Some conversions require more structural changes, which can affect the cost.
- Planning permission and regulations – Some loft conversions may require approval, depending on the modifications.
Here's an overview of each type:
Rear/Back Extension
A rear extension extends your home at the back, making it a great option for properties with a garden or outdoor space. This type of extension is ideal for creating open-plan living areas, larger kitchens, or dining spaces. It allows for plenty of natural light with options for bi-folding or sliding glass doors, bringing the outdoors in.
Benefits of a Rear Extension:
Side Return Extension
A side return extension is perfect for terraced or semi-detached homes with unused space along the side of the property. Extending this narrow strip, you can transform a cramped kitchen or living area into a bright, open, modern space.
Benefits of a side return house extension:
Single-Storey Extension
A single-storey extension is a versatile and cost-effective way to increase your living space. Whether you need a kitchen extension, a new living area, or a home office, this option allows you to extend outwards without altering the structure of your home too much.
Benefits of a single-storey extension:
Double-Storey Extension
If you need maximum space, a double-storey extension is an excellent investment. This type of extension allows you to add extra rooms both upstairs and downstairs, perfect for growing families or those needing additional bedrooms, home offices, or bathrooms.

House Extension Experiences and Feedback From Clients
“
VNP Constructions completed our rear extension and transformed our dark, cramped kitchen into a stunning open-plan kitchen/lounge area. Their service was exceptional, from the sleek bi-fold doors to the perfectly positioned skylights. The project manager kept us informed throughout, and the team was always professional and tidy. Finished on time and kept the agreed budget - couldn't ask for more!

Outstanding work by VNP Constructions on our side return extension. They turned an awkward, unused space into a gorgeous kitchen-diner that's now the heart of our home. Vasilis and the team were respectful of our home and neighbours, keeping disruption to a minimum. Communication was excellent!

I was quite nervous about adding an extension to our home, but Vasilis' expertise put me at ease. From the very first meeting, he was professional, knowledgeable, and transparent about the entire process. The team worked efficiently, stayed on schedule, and kept everything as tidy as possible. If you're looking for a reliable house extension builder in North London, I highly recommend VNP Constructions!
