Steel structures
Steel can enable large openings and different layouts. Calculations, detailing and installation must align precisely.

Timber structures & joists
Timber joists and structures connect room layout, spans and finishes. Their existing condition is an important starting point.

New brickwork and masonry repairs affect appearance and the way walls connect to the building.

Good lighting follows how a room is used. General, task and ambient light need not come from the same fitting.

Good drawings make ideas discussable and connect the concept, assessment and execution.

The difference starts
with a considered plan.
Exposed steel, timber or brickwork can define a room’s character. The structure then becomes a finished element too. Discuss connections, service routes and material transitions alongside structural design.
Can every structural beam remain exposed?
Assess structure, required protection and finishes first. Do not decide on appearance alone; include junctions and service space in the proposal.
Make the details clear.
Detail one connection with structural dimensions, visible finishes and adjoining materials. Have required protection measures and service space explicitly assessed.

discussing together.
Can every structural beam remain exposed?
Assess structure, required protection and finishes first. Do not decide on appearance alone; include junctions and service space in the proposal.
What work can I discuss?
Extensions, home renovation, structural changes, roof and facade work, installations and interior finishing. The necessary work and specialists are determined for the actual project.
How is a price established?
The existing building, scope, structure, installations, access and finishes determine the cost. A useful proposal may require a survey and further design information.
Is permission required?
This depends on the location, building and proposed work. Use the official Omgevingsloket and resolve uncertainty before scheduling construction.
What warranty applies?
Ask for applicable workmanship and product arrangements in writing, including scope, conditions, maintenance and how to report an issue.

When to involve a structural engineer — structure as part of the design
Your starting point: structure as part of the design. Structural questions belong early in design, especially for large openings, additional floors or changing loads.

Your starting point: structure as part of the design. Transitions between old and new affect whether an extension feels coherent. Differences in height, material and structure should be visible early.
