Engineering-led alterations with controlled temporary works
Structural Renovation Contractors London
North Star Building Solutions delivers structural renovation work across London, coordinating surveys, engineer information, temporary support, steelwork, masonry, floors, roofs and the surrounding building fabric.
From the engineer’s design to a safe site sequence
A permanent steel schedule does not describe every step required to install it. Existing load paths, access, lifting, temporary propping, bearing preparation and the order of demolition must be resolved against the real property. We review architectural and structural information before disruptive work begins and identify where opening-up or clarification is required.
Building Control, Party Wall matters, planning conditions, leasehold consent and freeholder requirements may overlap but remain separate responsibilities. The project team confirms the applicable approvals for the address and scope.
Load-bearing wall alterations
Openings are set out against the finished design, services and existing construction. Propping, demolition, bearings, padstones, steel placement, connections and fire protection are sequenced before finishes begin.
Temporary works
Needling, propping, bracing, excavation support and staged demolition protect the retained building during change. Designs and inspection requirements are matched to the method and site conditions.
Steelwork and structural connections
Fabrication information, tolerances, access and lifting are checked before delivery. Connections, packings, grout, restraints and corrosion or fire protection are inspected before enclosure.
Floors, roofs and openings
New stair openings, floor strengthening, dormers, roof alterations and double-height spaces affect more than one element. Deflection, trimming, insulation, ventilation and finishes are coordinated together.
Masonry and foundations
Cracking, movement or proposed new loads may require investigation. Foundation, lintel, pier and masonry repairs are developed from evidence rather than surface appearance alone.
Services and final integration
Pipes, ducts, cables and recessed fittings must not undermine structural elements. Routes are agreed with the design team before drilling, notching or closing the work.
Genuine project evidence
These genuine North Star photographs document groundworks, masonry, structural coordination and interior completion stages. They demonstrate relevant workmanship without naming a client or exact home address. The captions describe the stage shown; they do not claim that every image comes from the location named on this page.
Inspection before concealment
Structural bearings, bolts, welds, reinforcement, restraint straps, fire protection and service interfaces are checked while accessible. Building Control and engineer inspections are coordinated at the appropriate stage, and photographs or records are retained for the agreed scope.
After structure, the surrounding plastering, joinery, flooring, kitchens, bathrooms and decoration must follow the intended levels and tolerances. This is why structural work and fit-out are programmed as one connected renovation rather than separate contracts with an unmanaged gap.

Frequently asked questions
Do you provide structural engineering?
We coordinate with the appointed structural engineer. Permanent design and any required temporary-works design must be prepared by appropriately qualified professionals.
Can you remove a load-bearing wall?
Often, subject to survey, engineer design, bearing conditions, services, fire protection and Building Control. Temporary support is planned before the wall is altered.
What are temporary works?
They are the supports and construction arrangements needed to keep the building and workforce safe while the permanent structure is changed. They must match the real sequence, not only the final drawing.
Can structural work be completed in an occupied home?
Limited work may be possible with separation and controls, but major alterations are commonly safer in a vacant area or property. Access and escape routes must remain suitable.
How are hidden conditions handled?
The condition is recorded and reviewed with the design team. Revised details, programme and cost implications are agreed before related extra work proceeds whenever safety permits.
