Existing conditions
Available drawings, site measurements, floor levels, visible structure, rooflines and materials establish the starting point.

Home Renovations and Addition Design in Calgary
Existing-condition review, additions and coordinated renovation drawings
Major renovation design starts with the house as it stands. We document existing conditions, identify the elements to retain, and plan the junctions between new and old construction.
Starting Point
Home Renovation Design Calgary: Existing Conditions and Old-to-New Junctions
Major renovation design is different from planning a new home. Existing structure, floor levels, rooflines, windows and mechanical routes are already part of the problem, along with the parts of the house the homeowner wants to keep.
We begin with available records and a review of the areas affected by the work. Options compare reorganizing existing rooms, adding floor area, or combining both approaches.
Old and new construction must align at structural supports, weather barriers, floor and ceiling levels, trim, materials, circulation routes, and openings. Concealed conditions may remain unknown until construction and require review when uncovered.
Design Questions
Six Existing Conditions to Review Before Planning an Addition
Available drawings, measurements, structure, levels, rooflines, windows, and concealed conditions define what can be retained, removed, or added.
What is worth keeping
Rooms, materials or exterior features that still work can guide the new design and help focus the scope where change matters most.
Plan before adding area
Moving circulation or changing room relationships may solve part of the brief before an addition is sized.
Old-to-new connections
Floor transitions, roof intersections, structure, windows and exterior materials need to be resolved where the addition meets the house.
Light after the plan changes
An addition can improve one room while darkening another, so daylight is checked across both the existing and proposed spaces.
Site discoveries
Renovations can reveal concealed conditions. Clear records and coordination help the team assess changes when new information becomes visible.
Design Process
Renovation Design Stages and Deliverables
The process separates what is known, what needs investigation and what may remain uncertain until construction.
01
Record and review
We gather available property information and document the visible conditions in the areas affected by the proposed work.
02
Renovation options
Plans test what can be reorganized, where added area belongs and how the household can move through the completed home.
03
Old and new coordination
Floor plans, elevations and key junctions are developed with the structural and consultant input required for the scope.
04
Permit and builder drawings
The selected design becomes a coordinated drawing package, with known existing conditions clearly distinguished from proposed work.
Drawing Coordination
A clear line between existing, removed and proposed work
Renovation drawings distinguish existing, demolished, and proposed work and identify the sequence and limits of the changes.
Existing conditions within the agreed project area
Demolition and elements intended to remain
Proposed floor plans, additions and exterior changes
Key old-to-new junctions and level transitions
Consultant coordination and permit information appropriate to the scope

Common Questions
Questions About Home Renovation and Addition Design in Calgary
What information do you need about the existing house?
Available plans, a current survey or real property report, photographs and access to the areas affected by the work are useful starting points. Additional investigation may be recommended depending on the scope.
Can you help us decide whether to renovate or add on?
We can test how much of the brief may be met by reorganizing the existing plan and where added space could be useful. Construction cost comparisons should be prepared with a builder or cost professional using the developed options.
How do you make an addition feel connected to the house?
The connection is considered through floor levels, circulation, ceiling heights, windows, rooflines, materials and proportion. Matching every old detail is not always necessary, but the relationship should be deliberate.
Will a structural engineer be required?
Many major renovations and additions require structural input. The need and scope are confirmed based on the proposed changes and existing conditions.
Do renovation projects require permits?
Permit requirements depend on the property and scope of work. The applicable approval path should be reviewed before the drawing package is finalized.
What happens if construction reveals something unexpected?
The builder should document the condition before covering or altering it, and the relevant designer or consultant can then assess how it affects the work. Renovation projects need room in the communication process for these discoveries.
Can renovation drawings be used for builder pricing?
Developed drawings give builders a clearer basis for pricing than a verbal scope alone. Pricing accuracy still depends on site access, known existing conditions, specifications and the level of detail available at the time.
