Steel Beam

Frome Kitchen Expansion

Project Location : Frome, Somerset

Project Type : Residential

Project Scope : Removal of an internal load bearing wall to open up the space as part of a house renovation project.

Services Provided:

  • Steel beam analysis and design
  • Chimney stack validation

Open-Plan

Internal Load Bearing Wall

Open-plan kitchen-diner created by removing the wall between the kitchen and the existing dining room.

Engineering challenge

Limited headroom meant a slim beam was needed without dropping into the room.
 

Structural solution

We specified a steel section that sat within the existing floor zone with the joists hangered off either side.
 

Outcome

Flush ceiling across the entire new open-plan space.
 

Living Space

Internal Wall Removal

Knock-through between kitchen and living room in a 1930s semi.

Engineering challenge

The wall was load-bearing and sat directly under a stair trimmer.

Structural solution

Beam designed to pick up both the floor above and the trimmer load, with detailed bearing instructions.

Outcome

Bright, open living space connecting the kitchen and lounge.
 

Foundations

Garden Office Piles

Mini-pile foundations for a garden office close to a mature tree.

Engineering challenge

Heave-prone clay near a large oak ruled out conventional strip foundations.

Structural solution

Mini-piles with ground beams designed to take the load below the zone of seasonal moisture change.

Outcome

Stable foundation, Building Control approval, and the tree retained.
 

Outbuilding

Garden Office Complete

Timber-clad garden office finished and in use as a year-round workspace.

Engineering challenge

Lightweight building on a previously made-up section of garden.

Structural solution

Stiffened raft slab designed to spread the load and accommodate variable made-ground.

Outcome

A warm, dry, level garden office.

Extension

Two Storey House Extension

Two-storey side and rear extension to a semi-detached property.

Engineering challenge

Existing strip foundation needed underpinning at the join, plus a wide ground floor opening below a new bedroom.

Structural solution

Mass-concrete underpinning sequence, full steel frame at ground floor, and matching floor joist design above.

Outcome

Significantly larger family home, finished on programme.

Conversion

Complete Garage Conversion

Integral garage converted into a habitable room.

Engineering challenge

Original garage floor was below the internal floor level and lacked thermal performance.

Structural solution

Designed a new floor build-up with engineered timber joists and confirmed wall and lintel adequacy for the new opening.

Outcome

A warm, dry, fully usable extra room with minimal external alteration.
