Change of use of a room
If you want to convert an attic, storage area or undefined space into a bedroom, office or studio, the new layout must be clearly recorded and the space must be assessed for technical suitability.

Need floor plans and building drawings?
A renovation does not begin on site, but on paper. Whether you are planning a loft conversion, an extension, a new layout or a structural alteration, clear floor plans and building drawings form the basis for safe execution, clear communication and a permit-ready plan.
At Aboss Bouwadvies – Architects & Structural Engineers, we prepare professional architectural drawings, floor plans, technical detailing and, where required, structural substantiation. This gives you a dossier that is usable for you, the contractor and the municipality.
Why building drawings are indispensable
In a renovation project, a rough sketch is rarely enough. As soon as a space is reconfigured, a structure is altered or a permit is required, accurate drawings become essential. They show the existing situation, the proposed changes and how the plan is technically executed.
What good drawings make possible
- testing feasibility before work starts;
- preventing execution mistakes on site;
- making structural consequences visible in advance;
- submitting a complete and correct permit application;
- reducing disputes afterwards with contractor, municipality or insurer.
What goes wrong without proper technical drawings
Without clear drawings, uncertainty quickly arises about dimensions, structure, detail junctions and responsibilities. In practice, that leads to delays, extra cost and unnecessary risk.
When do you need floor plans or building drawings?
Structural alterations
When removing a load-bearing wall, creating an opening in a floor, placing a steel beam or making a stair opening, a technical drawing is required. Together with the calculation, it forms the basis for a safe intervention.
Permit applications
For a dormer, roof extension, rear extension or other building alteration, the municipality usually asks for drawings of the existing and proposed condition. Depending on the plan, sections, elevations and structural data may also be required.
Clarity for the contractor
A contractor must be able to see exactly what has to be built. Incomplete or vague drawings increase the risk of incorrect execution, additional costs and delays on site.
Evidence for sale or legalization
During a sale, when reviewing renovation history, or when legalizing previously executed work, building and structural substantiation is often requested. A proper dossier provides clarity and confidence.
What Aboss provides
We do not simply deliver a drawing. We provide a technically usable package that fits the nature of your project.
Existing and proposed floor plans
Clear architectural drawings showing how the property is currently arranged and how the new situation will be realized.
Elevations, sections and dimensions
Where required, we also prepare elevations, sections and dimensions so the plan can be assessed and executed clearly and consistently.
Technical details
For structural or architectural interfaces, we work out detail solutions, for example for:
- stair openings and trimming structures;
- steel beams and portals;
- floor and roof alterations;
- junctions for extensions, dormers or roof additions.
Structural substantiation
If the renovation affects the load-bearing structure, we also provide structural calculations and structural drawings. This demonstrates that floors, beams, supports and walls meet requirements for strength, stability and serviceability.
Permit-ready drawing sets
For projects that require a permit, we assemble complete sets for submission to the municipality, tailored to the scale and nature of the plan.
Our process
We work in a structured way so you know in advance what to expect and the technical quality of the dossier remains reliable.
- Project intake: we discuss your wishes, the existing condition and the intended interventions.
- Survey and information gathering: we work from existing drawings, photos, archive material and site dimensions.
- Technical development: your wishes are translated into a building plan and, where required, a structurally responsible solution.
- Delivery of drawings: you receive the final set in a form that is usable for contractor, client and municipality.
One clear technical line matters most in combined interventions
In practice, renovations often consist of several interventions at once. Think of a dormer combined with a new stair, an attic reconfiguration with an extra opening in the floor, or an extension with a breakthrough in the rear façade. In such cases, one consistent technical substantiation is essential.
When architectural drawings, structural interventions and permit-related issues are handled separately, contradictions often appear in the dossier. That causes delays with the municipality and uncertainty during execution. Aboss combines these components into one consistent technical package.
Common mistakes without professional drawings
- a floor build-up or new wall that is heavier than the existing structure can carry;
- a stair opening created without a correct trimming structure;
- unclear dimensions leading to changes during construction;
- missing substantiation in a permit application;
- disputes afterwards with municipality, contractor or insurer about what was actually changed.
The practical result
These mistakes may seem small in the design phase, but during execution they can lead to major additional costs, repair work or standstill. A solid drawing package prevents such risks from only becoming visible on site.
Frequently asked questions
When are architectural drawings alone sufficient?
For simple layout changes or non-structural works, architectural drawings may be sufficient. As soon as load-bearing structure, permits or technical details become relevant, additional technical development is usually needed.
When is a structural calculation required?
Structural calculations are often required when removing load-bearing walls, making stair openings, building extensions, creating roof additions, forming openings or carrying out other structural alterations.
Can you also prepare permit documents?
Yes. For projects that require a permit, we can prepare complete submission sets for the municipality, including architectural drawings and structural substantiation where needed.
Can existing drawings be used as a starting point?
Yes, provided they are current and reliable. We assess existing material critically and supplement it where necessary with measurements, photographs, archive documents or a site survey.
Who are the drawings intended for?
For you as client, for the contractor during execution and for the municipality during review or permit assessment. That is exactly why they must be technically clear and unambiguous.
