Tell us what you’re planning.

Whether it’s a bigger kitchen, an open-plan downstairs or a wall you’ve pictured coming down for years, send the details here first. We’ll point you at the cleanest next step:

  • “Who do I speak to first?”
  • “What’s the actual first step?”
  • “Does my project need planning permission?”
  • “Do I need Building Control?”
  • “Which certificates do I end up with at the end?”
  • “Who keeps the whole thing compliant?”

Drop a few details below and we'll tell you who should be involved first: designer, engineer, Building Control or builder.

Quickest route: send the project details, or call if it is urgent.

How we run it

By the time a builder’s in your house, here’s what you’ll already have.

An accurate 3D scan of your property. Engineered drawings signed off by a structural engineer. A Building Control strategy already scoped. A fixed build quote tied to every line of the drawings. The decisions that cost £10k to fix on site cost nothing to fix here, on paper.

1Start here

Design & ApprovalsGet the answer before site money is spent

Every £10k decision on site started as a £0 decision on paper. Beam sizing, padstone spec, Building Control detail, how the opening meets the floor — hundreds of projects have taught us exactly where the answers sit. The design stage is where we work those answers out, on a screen, before anyone’s standing in your kitchen holding a drill.

  • We confirm what you want to change and what is likely carrying load.
  • We map the survey, drawing, engineering and approval route.
  • We flag planning, Building Control and party-wall risks before pricing.

Typically: Usually 1–2 weeks from first survey to design route

    Planning / Building Control Route

    Choose the clean approval path

    • We confirm whether planning, lawful development or Building Regulations only applies.
    • The engineer's requirements are built into the drawings before build pricing.
    • Building Control is prepared around what will actually be inspected on site.

    Timeframe: Usually 2–5 working days after survey information is complete

  2. Workers forming a structural opening during renovation

    Installation

    Steel in, wall down, room made good

    • We sequence the structural work around access, protection and inspection points.
    • The steel and padstones are installed to the engineer's design.
    • Openings are made good so the room is ready for the next trade or finish.

    Timeframe: Most wall-removal installs run 1–3 weeks depending on complexity

    Sign-off

    Certificates and project record closed out

    • We keep the inspection trail together instead of leaving certificates scattered.
    • Any snags or evidence requests are closed before handover.
    • You receive the drawings, calculations and completion record for resale.

    Timeframe: Closed as soon as Building Control completes the final inspection

5.0 / 5 on Google

Josh is very knowledgeable and offered lots of ideas in planning our extension. Paperwork and communication was punctual and always well documented. His team were a pleasure to have in the house, they were very clean, tidy and respectful to our (and our neighbours) property. I would not hesitate to recommend this company, they can do everything from start to finish for you.
Sandra W.Apr 2026
Called Josh in to draw up some plans and come up with some ideas for a small extension. Josh was prompt in getting in touch and carried out layout drawings for a very reasonable amount. Josh also gave us a budget price to carry out the works.
Lee B.Aug 2024
I couldn't recommend Josh enough! He has been absolutely fantastic, nothing was too much trouble, he was happy to bounce lots of ideas back and forth until we were happy. He is polite, friendly and professional in every aspect. I would definitely be using his services again in the future when needed.
Kirsty H.Jan 2024
Josh got the plans for our extension completed and submitted very quickly. We had a number of amendments and obstacles to overcome but nothing was too much trouble for him. A very professional and efficient service.

Before you start

Common questions

How much does a typical wall removal cost?+

Most internal wall removals with a steel beam — including survey, drawings, engineering, Building Control and installation — fall between £6,500 and £9,500 inclusive of VAT. Larger openings or multiple walls run £9,000–£14,000. Combined extension and knock-through work typically runs £12,000–£18,000. You'll get a fixed price at the end of the free discovery call and site visit.

Does my job need planning permission?+

For most internal wall removals and kitchen knock-throughs, no. These are usually covered under Building Regulations only. Rear extensions within Permitted Development don't need planning permission either — they need a Certificate of Lawfulness if you want council confirmation on paper. We'll tell you which route applies on the free discovery call.

Do I need structural calculations?+

If you are removing or altering a load-bearing wall, yes. A structural engineer must design the replacement support — typically a steel beam (RSJ) with padstones. We handle this as part of the package.

Do I need building control for removing an internal wall?+

Yes. Any structural alteration requires a building control application. The inspector will check the steelwork before it is covered up. We manage the full process from application to sign-off.

Can you install the steel as well?+

Yes. We provide the full package — survey, plans, engineering, building control and installation. You do not need to find a separate contractor.

Can you help with kitchen knock-throughs?+

Absolutely. Kitchen-to-dining and kitchen-to-living knock-throughs are our most common job. We assess the wall, design the opening, install the steel and make good.

What happens at the survey?+

We measure the rooms either side of the wall, check the wall construction, look at what is above and confirm whether the wall is load-bearing. The visit takes around 30 to 45 minutes.

How quickly can you provide plans and calculations?+

Floor plans are typically delivered within 5 working days of the survey. Structural calculations follow within 5 working days after that. If you need it faster, ask about our priority service.

How long does a typical project take, start to finish?+

Most projects run 6–8 weeks from first call to completion. Design and approvals typically takes 2–4 weeks. Installation on site is usually 1–3 weeks depending on complexity. We'll give you a clear schedule before work starts.

What if the project goes over budget?+

The price we quote is fixed. Once we've surveyed the property and specified the steelwork, the number we give you is the number you pay — unless you change the scope mid-project. We tell you clearly what's included and what isn't before you commit.

What if planning or Building Control is refused?+

Building Control refusals are rare for internal alterations. If there's an issue, we redesign and resubmit at no extra cost. For planning, we assess your chances before we start — if permission is uncertain, we'll tell you upfront and explain your options.

Do I need to worry about party wall agreements?+

If your wall removal affects a wall shared with your neighbour, you may need to serve a Party Wall Notice. We flag this early, explain your options (agreed surveyor vs separate surveyors), and handle the back-and-forth so you're not stuck negotiating. If the wall is wholly within your property, there's no party wall issue.

Can I take the drawings to another builder?+

Yes. The drawings are yours. If you decide mid-project to go elsewhere for the build, we'll invoice for the design and engineering work completed and hand everything over. Most customers stay with us because we've engineered the work and warrant the installation, but you're not locked in.

Can you help me if I want to DIY the finishing work?+

Yes. We do the structural part — the wall removal, steel installation and making good. Plenty of our customers handle the finishing (tiling, flooring, decorating) themselves or through their own trades. If you get stuck with anything non-structural, we're happy to take a call and talk you through it. We'd rather you got a good result than struggled alone.
