At what stage should you hire an interior designer? by DCondo Design

When most people begin planning changes to their home, they instinctively think the first step is hiring an architect. They shortlist a few, review portfolios, and then select the one they feel most comfortable with. What’s rarely considered, however, is that architects focus primarily on structure and layout rather than on how a space will actually feel and function day-to-day.

Light and flow

Architects shape the skeleton of a home — the walls, extensions, and circulation routes — but rarely focus on how interior elements interact. Without early input from an interior designer, small yet crucial details like furniture placement, window alignment, and door swing often disrupt the natural flow of a space.

Many homeowners rush through planning to secure approvals and start building work. Consequently, interior layouts, lighting, and room proportions become an afterthought. This can lead to awkward spaces or missed chances to improve natural light, connection, and comfort. Once planning permission is granted, meaningful design changes often become impossible or costly.

Engaging an interior designer early can transform the process. They consider light sources, furniture scale, and flow from the outset — ensuring every room functions beautifully once complete. By collaborating before submitting plans, homeowners can avoid compromise later and create spaces that look, feel, and work exactly as intended.

Early planning

It’s always best to involve an interior designer before the architect finalises drawings. Often, your current footprint holds more potential than expected. A professional designer can identify practical adjustments or reconfigure existing space to improve layout, light, and usability — avoiding unnecessary extensions or structural work.

An interior designer sees beyond walls and windows. They anticipate how each space will be lived in and can prevent design regrets later. A few early adjustments might save thousands, which can then be reinvested into higher-quality finishes or bespoke joinery.

Common pitfalls

One of the most frequent oversights is leaving kitchen planning too late. The kitchen is the heart of the home, yet its flow, storage, and lighting are often determined only after construction begins. Early collaboration between architect and interior designer ensures every centimetre works efficiently and looks cohesive.

Many clients dream of a kitchen island. While not all homes can accommodate one, thoughtful planning often makes it possible without compromising usability. Considering circulation and proportion from the start allows the island to feel integrated, not squeezed in as an afterthought.

Designing your space

When approaching your living or dining areas, start with purpose. Is it a formal entertaining space, a relaxed family hub, or a flexible open-plan zone? Defining how you’ll use the area informs every choice thereafter — from proportions to furniture selection.

The primary pieces, such as a sofa or dining table, anchor the room’s aesthetic. Their placement determines balance and flow, so it’s vital to get this right before walls or lighting points are fixed. Likewise, smaller furnishings, mirrors, and statement lighting bring warmth, texture, and depth.

Don’t underestimate the importance of layering. Rugs, cushions, and soft lighting create intimacy and harmony, while statement furniture pieces bring personality. Combining these elements with considered layout ensures the final design feels natural and cohesive.

Summary

Before starting any renovation, clarify your goals. Are you seeking more space, a layout refresh, or a better connection between rooms? Once clear, review your budget and explore whether a reconfiguration might deliver the same impact as a costly extension.

Consulting an interior designer at the earliest stage can save time, money, and frustration. They’ll help align your structural plans with practical living needs — ensuring the kitchen, bathrooms, and core spaces are designed correctly from the start. Essentially, it’s about creating a home that works as beautifully as it looks.
