Building additions
Rear and side extensions, rooftop additions, new stories, terraces, decks, and connections between new and existing systems.
Structural engineering
Renovations, Alterations & Extensions
We connect new design ambitions to existing buildings through careful investigation, coordinated modifications, and structural systems tailored to the realities already on site.
Discuss your projectWhat we do
Make more of the building you already have.
Renovation engineering requires a clear picture of how an existing building carries load, how prior changes may have affected it, and how the proposed work will alter those paths. We combine field observations, record-document review, selective investigation, and analysis to design compatible new work.
Our team coordinates structural interventions with architecture, building services, façades, neighboring properties, and construction sequencing. The objective is a solution that delivers the desired space while limiting unnecessary demolition, material, and disruption.

- Vertical expansions
- Adaptive reuse
- Major structural openings
Capabilities
Focused support.
Complete perspective.
Scope is tailored to the project, from a focused evaluation to full design and construction-phase services.
Interior alterations
Column removal, enlarged openings, stair and elevator openings, mezzanines, and open-plan conversions.
Adaptive reuse
Structural evaluation and modification for new occupancies, loads, equipment, layouts, and code requirements.
Urban coordination
Underpinning, temporary stabilization, support of excavation, party-wall considerations, and constrained access.
Our process
From question to
buildable direction.
Understand
We establish goals, existing conditions, constraints, available information, and the decisions the engineering must support.
Analyze
We evaluate loads, materials, systems, code criteria, interfaces, and practical alternatives.
Document
We communicate the selected solution through clear calculations, reports, drawings, details, or specifications.
Support
We remain available through review and construction to answer questions and respond to field conditions.
Frequently asked
Good questions lead
to better projects.
Can an existing building support another story?+
A structural evaluation is needed to assess the existing roof, floors, walls, columns, lateral system, and foundations. Where capacity is limited, we can study reinforcement or alternative lightweight systems.
What information is helpful at the start?+
Existing drawings, surveys, photographs, proposed architectural plans, known building history, and access for observation all help establish scope efficiently.
Do you design temporary support for renovation work?+
Yes. When the permanent work requires removal or alteration of load-bearing construction, temporary shoring and sequencing may be incorporated into the engineering scope.
