Upper Storey Extension & First Floor addition

“If we start again or do another build, we certainly would choose the Rossmark Team. “ – Rhett and Sue

When considering options to expand your home, an upper storey extension presents a compelling opportunity to maximise your living space while preserving valuable outdoor area. This strategic choice allows homeowners to add a master retreat, a dedicated teenage level, or a versatile family rumpus room without compromising outdoor liability.

However, embarking on an upper-level extension involves careful consideration of various regulatory and structural factors.

Authority design constraints such as floor space ratio, height limitations, overshadowing of adjoining properties, and boundary setbacks must be thoroughly reviewed to ensure feasibility. Additionally, structural assessments are crucial: Can your existing home support another level? Would you consider removing lower walls to enhance floor plan connectivity?

Our team oversees every aspect from initial design concepts and authority applications to detailed documentation and construction.
