Renovation and expansion planning

Adding rooms, adding a floor, or reworking what is already there without starting again.

Two sections of the same house, one renovated and one rebuilt, showing what each keeps Two cross-sections side by side on a single shared ground line, because the lot is the one thing neither option changes. In the first, the foundation, the walls and the roof frame are drawn as solid lines because a renovation keeps them, while the internal partition, the openings and the finishes are dashed because they are replaced. In the second, everything above the ground is dashed, because a rebuild replaces all of it. A legend below the two sections pairs a solid line with the word kept and a dashed line with the word replaced. renovate rebuild kept replaced
The difference is not how much work happens. It is how much of the existing house survives the work. A renovation is bounded by what the structure will already carry, which is why the condition of the foundation and the frame decides the question before budget does.
Three ways to add space to a house: out, up, and within Three small elevations side by side. In the first, a new single-storey wing is added beside an existing house, stopping short of a dashed lot boundary, with an unnumbered arrow marking the setback between them. In the second, a new storey is added on top of the existing house, with the footings under its walls marked. In the third, the open carport beside the house is enclosed and hatched as a new room under the roof it already has. 1 out 2 up 3 within setback check footings carport to room new wing new storey
Each way of adding space has its own first question. Out: how much of the lot is left once the setbacks and the coverage limit are counted. Up: whether the existing footings, columns and beams can carry another floor, which only an engineer can answer. Within: whether the space can meet the rules for a room, with light, air and ceiling height. Illustrative, not to scale.
Design concept: a single-storey concrete house with a lighter clad second floor added above it, a new metal roof and an external steel stair at the side
Design concept Building up: a lighter second floor on the existing house, with its own stair outside so the rooms below keep their layout. Generated image: it is not a photograph, a built house, or the practice's work.
