Side Extensions Carlton
Make the most of the narrow gap down the side of your Carlton home. A side extension turns wasted alley space into a bright kitchen, utility room, or wider hallway that suits how your family actually lives.
We are a local Carlton team with 15 years of experience building side infill and side-return extensions on Victorian terraces, 1930s semis, and modern homes across the area.

Side extensions built for Carlton homes
Many streets in Carlton, from the terraces around Carlton Hill to the semis off Standhill Road, have a useful strip of land down one side of the house. On its own that space is often too narrow to do much with, but built out it becomes some of the most valuable floor area you can add.
A side extension widens your home rather than pushing it back into the garden. That makes it perfect for opening up a cramped galley kitchen, adding a downstairs WC and utility, or creating the wide open-plan space that modern Carlton families want without losing the lawn.
Because we work in Carlton week in and week out, we know the local mix of building ages and how each one behaves. We match new brick to your existing elevation so the extension looks like it has always been part of the house.
Why a side extension?
Ideal for narrow homes where the garden is small but there is unused land at the side. You gain width, light, and layout without giving up outdoor space.
Local & accountable
A Carlton-based team you can visit and phone. We stand behind every build with a structural guarantee.
What a side extension adds to your Carlton home
- More usable width – Turn a narrow kitchen or hall into a proper open-plan space the whole family can use.
- Keeps your garden – Build into the side alley instead of the rear, so Carlton homes with small gardens keep their outdoor room.
- Better natural light – Rooflights and new side windows brighten rooms that used to feel dark and boxed in.
- Added value – A well-finished side extension is one of the strongest returns on investment for terraces and semis in the NG4 area.
- Room for the extras – Space for a utility, downstairs WC, boot room, or home office without cramping the main house.
- Seamless finish – Matched brick, roofline, and rendering so it blends with the rest of your street.

Planning and permitted development
Many single-storey side extensions in Carlton fall under permitted development, which means no full planning application is needed. Side extensions must usually be single storey, no more than half the width of the original house, and no higher than four metres.
Two-storey side extensions, homes in a conservation area, and any property that has already been extended will normally need a planning application to Gedling Borough Council. We handle the whole process for you and have a 100% success record on the applications we submit.

What Carlton homeowners say
Our side alley was dead space for years. They turned it into a wide kitchen-diner and matched the brick so well you cannot tell where the old house ends. Spotless work throughout.
A local Carlton firm that actually turned up when they said they would. The side return gave us a proper utility and downstairs loo. Clear pricing and no surprises at the end.
They handled the planning with Gedling and kept us updated the whole way. The extra width has completely changed how our 1930s Carlton semi feels. Highly recommend.
