Smarter Home Extensions and Commercial Projects Across Liverpool
Looking for home extensions Liverpool? At Acero Designs, we build fast, precise steel frame extensions, garden rooms, and commercial projects across the city. It is a modern method that gives you a stronger, more accurate structure in less time, with far less disruption at home.
Traditional extensions often mean weeks of delay, deep foundations, and rising costs. Steel framing avoids much of that. Your frame is precision-made off site, then assembled quickly at your property.
Why homeowners across Liverpool choose steel frame
- Faster build times, so your home is disrupted for less time
- Strong, accurate structures that will not shift, warp, or crack
- Lower long-term maintenance than timber or brick
- Better insulation performance and energy efficiency when installed correctly

Which Home Extension Is Right for Your Liverpool Property?
Every home and budget is different. Here are the extension types we build most often across Merseyside, each engineered in a steel frame for speed and structural accuracy.
Rear Extensions: Open up the back of your home into a bright, open-plan kitchen and dining space, with wide garden access through bi-fold or sliding doors.
Side Return Extensions: Reclaim a narrow, unused side alley to widen your kitchen or living space, ideal for Liverpool’s many terraced and semi-detached properties.
Double-Storey Extensions: Add space above and below in one build, gaining extra bedrooms or a bathroom suite. The most cost-effective way to add significant square footage.
Wrap-Around Extensions: Combine a side return and rear extension to completely reconfigure your ground floor into a large, modern living hub.
Not sure which suits your home? Talk to us about your extension, and we’ll advise honestly on the best option for your property and budget.
- Our Process
How We Build Your Extension, Step by Step
We keep the whole process clear and structured, so you always know what happens next.
1. Free Consultation & Site Visit: We visit your property, review your goals, and assess the structure and access.
2. Design, Quote & Planning: You get a clear, itemised quote. Once agreed, we handle the drawings, structural calculations, and building regulations details.
3. Off-Site Steel Manufacturing: Your frame is precision-made off-site while groundworks are prepared, saving time and reducing on-site mess.
4. Construction & Handover: We assemble, finish, complete inspections, and hand over your finished space.
- Planning & Building Control
Do You Need Planning Permission for an Extension in Liverpool?
Not always. Many single-storey rear and side extensions fall under permitted development, meaning no full planning application is needed, provided they stay within set height and depth limits (often up to 4 metres for many properties). Double-storey builds, or homes in Liverpool conservation areas such as Woolton and Aigburth, usually need formal planning permission.
Every build must also meet UK building regulations for structural safety, insulation, and fire performance. We help you understand what applies to your project and coordinate the details with Liverpool City Council building control, so the process stays stress-free.

every frame designed around your exact specification.
Common questions, answered honestly:
- Will a steel frame really save time? Yes. The frame is manufactured off-site and assembled quickly, so weather delays and slow bricklaying don’t hold up your build.
- Can I stay in my home during the work? In most cases, yes. For standard rear or side extensions, we isolate the work area to keep the rest of your home clean and usable. We’ll advise you honestly if a larger build makes this impractical.
- How do you handle cost? You get a clear, itemised quote before work starts, so there are no surprises.
