02 — RSJs
What RSJ installation involves
An RSJ is a steel beam that holds up the house where a wall used to be. An engineer works out how big it needs to be. It rests on concrete pads called padstones. Building Control inspects it before it is covered up.
What this covers
- A visit to measure the opening and check how the beam can be brought into the house.
- Structural calculations from an engineer, which set the size of the beam.
- Details of the concrete pads the beam rests on, called padstones.
- Building Regulations approval.
- Fitting the beam, the Building Control inspection, and repairing the walls, ceiling and floor.

What your project is likely to need
Your answer appears here as soon as you have answered the questions.
How a building project works
Every extension, knock-through or loft conversion has four stages. We do all four.
- 01
Drawings
We measure your house and draw it as it is now. Then we draw the new layout.
- 02
Approvals
We apply for planning permission if you need it, and prepare the Building Regulations drawings. Building Control is an independent inspector. They check the work and sign it off.
- 03
Engineering
A structural engineer works out the size of any steel beams and foundations before building starts.
- 04
Building work
We do the building work and finish the rooms.
For an RSJ, the engineer sets the size of the beam before any work starts on the wall.
What can go wrong, and how we stop it
What goes wrong
How we stop it
The price goes up once building starts.
We price the building work from our own finished drawings, so the price is agreed before work starts.
The steel beam is the wrong size, or rests on the wrong thing.
A structural engineer sizes the beam and what it rests on before building starts. Building Control checks it on site.
Old chimney breasts, pipes or cables turn up once the wall comes out.
We look at what the wall holds up and what runs through it before the drawings are finished.
A neighbour dispute holds the job up.
We tell you early if the Party Wall Act applies, so notices go out before the work is planned.
You find out too late that you needed planning permission.
We tell you at the free review whether you need planning permission, and we make the application if you do.

“…they can do everything from start to finish for you.”
“…carried out layout drawings for a very reasonable amount. Josh also gave us a budget price to carry out the works.”
“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.”
“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.”

Questions about RSJ Installation in Poole
What does RSJ stand for?
Rolled steel joist. Most people use it to mean the steel beam that holds up the house where a wall has been taken out.
Can an RSJ be fitted without Building Control?
It shouldn't be. Without Building Control approval you have no record that the work was checked, which can cause problems when you sell the house. We include the approval in the job.
Do you arrange the engineer?
Yes. We arrange the survey, the structural calculations, the Building Regulations approval and the fitting.
Tell us what you want to change
Send a few details and we will call you back the same working day to tell you what your project needs. There is no cost and no obligation.
We build in Poole, Bournemouth, Christchurch and about 20 miles around them.
