About our structural calculations service in New Milton
New Milton has a mix of housing, and structural calculations need a slightly different approach in each. We also work in nearby Bournemouth, roughly 9.7 miles away. Whatever the age of the property, the steel goes in on proper bearings with temporary support in place throughout.
Building control will not approve a beam on trust. Before steel goes in, someone has to show in writing what the beam is carrying, what size it needs to be and how its ends are supported. That is the job of structural calculations, prepared by a qualified structural engineer from measurements taken at the property.
Things to plan for
- The beam ends are designed as carefully as the beam. Calculations check that the masonry under each end can take the concentrated load, and specify a padstone, spreader or column where it cannot. Weak brickwork beneath a bearing is a common reason for design changes.
- How long calculations take depends on the engineer's workload and how complicated the job is. A single beam is quicker to design than a loft conversion with several steels, and any opening up needed for investigation adds time before figures can be issued.
- The calculations or the building control approval usually state the fire resistance the steel needs, commonly 30 minutes in typical houses. That requirement then decides whether the beam is boxed in fire-rated plasterboard, painted with intumescent coating or protected another way.
- The cost of calculations rises with complexity: the number of beams and columns, whether loads come down from several floors, whether foundations need designing, and how much investigation is needed on site. A single straightforward beam sits at the simpler end.
- Keep the final calculations and drawings with the building control completion certificate. Together they show a future buyer, lender or surveyor exactly what was installed and why, and they help any later alterations to build on a known design.
From survey to sign-off in New Milton
Look and measure
We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
Building control
We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.
Fit, inspect, finish
The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Building rules for New Milton
In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either the local council's building control team or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.
If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Questions about structural calculations in New Milton
Do you cover New Milton for structural calculations?
Yes. We carry out structural calculations in New Milton and the BH25 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
Do I need a party wall agreement for structural calculations in New Milton?
Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.
How long do structural calculations take?
It varies with the engineer's workload and the complexity of the design, so there is no fixed turnaround. A single beam in a straightforward wall is usually quicker than a loft conversion or a frame with foundations. Any site investigation needed first, and any building control queries afterwards, add to the overall time.
Does the engineer need to visit my house?
Usually, yes, or at least work from a detailed survey of the property. The engineer needs accurate spans, joist directions, wall construction and an understanding of what sits above the opening. Calculations based only on a floor plan or photos risk missing loads, which can lead to redesign once work starts.
What happens if building control questions the calculations?
The engineer answers the query, usually by providing extra checks, clarifying an assumption or adjusting the design. This is a normal part of the approval process and does not mean anything is wrong. Work on the affected element waits until building control is satisfied, and any design change that affects cost is priced before it goes ahead.
