Walk each space at morning, noon, and late afternoon, noting tasks, glare, and gloomy corners. Photograph from the same spots to compare changes. Mark outlets, HVAC runs, and attic obstacles above. Small discoveries—like a dark hall used hourly—often guide smarter investments than chasing the showy, rarely used guest room.
Stand outside and study south and west exposures for intensity, while cool north light may suit studios or kitchens. Track deciduous tree shade in summer versus winter. Use free sun‑path apps to imagine shafts and tubes, preventing disappointment from misaligned domes, chimneys, or neighbor additions casting stubborn shadows.
Define what success means: bright breakfast prep without glare, safer stairs, a cheerier nursery, or energy savings from fewer switched‑on bulbs. Clear goals shape skylight size, well geometry, diffuser choice, and shading strategies, ensuring upgrades feel intentional, restorative, and genuinely life‑improving rather than merely decorative showpieces.
