Is an Interior Designer Worth It for a Renovation? What You’re Really Paying For
And whether AI, Pinterest and a little creativity are enough to get the home you really want.
By Tor Cooper · 6 min read · Interior Design Brighton, Behind the Scenes, Working with a Designer, Interior Design Process
If you’re planning a renovation, you’ve probably already spent hours scrolling Pinterest, saving Instagram posts and imagining what your home could look like. Perhaps you’ve even experimented with AI interior design tools, uploading a photo of your sitting room or kitchen and watching it transform into something that looks straight out of a magazine.
It’s exciting, isn't it? And with so much inspiration available at the touch of a button, it’s understandable to wonder whether hiring an interior designer is still worth the investment. After all, surely you can find the furniture, choose the colours and pull everything together yourself?
The honest answer is that you absolutely can do some of this yourself. But designing a home on screen that you love and successfully delivering a renovation that works in real life are two rather different things.
When you’re investing a significant amount of money in your home, particularly if you’re renovating a property you intend to stay in for years to come, the question isn't simply whether you can create a beautiful room. It's whether you can make the right decisions, avoid expensive mistakes and bring everything together in a way that works for you, your family and the way you live. And absolutely bring along your Pinterest boards to our discovery session - it's a great way of seeing some commonalities amongst your pins about what you are drawn to. But it is just a starting point for us.
As an interior designer working with homeowners in Brighton & Hove and across Sussex, this is where I believe professional interior design can make a real difference and save you money, time and overwhelm too.

AI can give you inspiration. But will the design work in your home?
We have to start with AI, because it has genuinely changed how we explore interior design ideas. AI interior design tools can be brilliant for experimenting with colour schemes, exploring different styles and visualising what a room might look like with a different layout or finish. They're a useful starting point, particularly if you struggle to imagine how a space could be transformed. But an AI-generated image is not the same as a considered interior design scheme.
The image might show a beautiful sofa, perfectly positioned artwork and a wonderful combination of colours. Yet the sofa may not be a real product, the proportions might be inaccurate, and the furniture may not leave enough room to walk comfortably through the space. AI is giving a flavour of the 'feel of the space but not whether it will work in practice. It also won't necessarily tell you whether that deep green paint will work in your north-facing sitting room, whether the dining table is the right size for your family or whether the beautiful pendant light will actually illuminate the room properly.
A visual can show you what a room might look like. An interior designer helps you work out what will actually work.
When I design a room, I'm considering the practicalities alongside the aesthetics: measurements, sightlines, circulation, furniture scale, natural light, artificial lighting and how the space connects to the rest of the house. AI can't consider how flow works into and out of spaces or if everything feels cohesive as you move through them.
It's about translating inspiration into a design that can be delivered, using real products and finishes, within your budget.

A beautiful home should feel like you, not a Pinterest board
One of the biggest challenges when renovating is working out what you genuinely want. You might love a contemporary kitchen on Instagram, a colourful sitting room in a magazine and the calm, neutral bedroom of a friend's house. Individually, they all look wonderful. But how do you bring together the things you love to create a home that feels cohesive and personal?
And what if you don't know what your style is called? That's absolutely fine. A big part of my job is listening, asking the right questions and understanding what makes a home feel right for you. It's not just about which colours you like or whether you prefer modern or traditional furniture. It's about how you live, what you need from your space, what you want to keep and how you want to feel when you walk through the door. I always find the most important design decision isn't what to add. It's recognising what isn't working, what can be reused and where a change will make the biggest difference.
AI can help you explore possibilities, but it relies on the information you give it. A conversation with an interior designer can uncover things you haven't yet thought to ask for, challenge an assumption or help you discover a direction you hadn't considered. Your home should tell your story, not simply recreate a look you've seen somewhere else. Why not share your Pinterest and AI renders with me and we can chat?

Colour, light and materials are different in real life
Have you ever chosen a paint colour that looked perfect on a sample card, only to find it looked completely different once it was on the wall? You're not alone.
Colour is affected by the direction a room faces, the amount of natural light it receives, the time of day, the artificial lighting you use and the colours and materials surrounding it. A warm neutral can look beautifully soft in one room and unexpectedly pink or grey in another.
The same applies to fabrics, flooring, tiles, worktops and wood finishes. A combination that looks harmonious on a screen may feel quite different when the actual materials sit together. An experienced interior designer considers these relationships as part of the overall scheme. It's not simply a case of choosing a paint colour you like; it's understanding how that colour behaves in your home and how it interacts with everything around it.
The same judgement applies to scale and visual weight. A large, dark sofa can anchor a generous sitting room beautifully, but overwhelm a smaller one. A delicate pendant might disappear into a room with high ceilings, while a substantial light fitting could become the perfect focal point. A rug can help define a seating area, but if it's too small, the furniture can look disconnected.
These details are difficult to judge from inspiration images alone. They require an understanding of how objects occupy a space, how the eye moves around a room and how the different elements work together.
It's often these seemingly small decisions that make the difference between a room that looks almost right and one that feels right.

Renovating a home is about more than choosing finishes
This is perhaps the biggest reason to consider hiring an interior designer for a renovation. When you're refurbishing a whole house, or undertaking a substantial kitchen extension or ground-floor renovation, the design decisions don't happen in isolation.
Where will the lighting go? What sort of lighting do you need? Does the furniture layout work with the proposed electrical positions? Have you considered window treatments before deciding where the radiators will sit? Will the flooring, kitchen cabinetry and wall colours work together? Have you allowed for the storage you need, rather than trying to squeeze it in at the end? These decisions are interconnected, and some need to be made much earlier than you might expect. It's easy to focus on the exciting visible elements while overlooking the practical details that will affect how the room works once it's finished.
An interior designer can help establish a joined-up vision for the home, identifying what needs to be decided first and how the individual choices affect one another. There is an order and process around renovations and working with that to define when decisions need to be made by and understanding the impact of late decisions is important. And that means you don't have to make every decision on day one. Nor does it mean you need to renovate every room at once. You can work in phases, provided there's a plan for the bigger picture.
Getting the overall direction right early on can help prevent the frustration of discovering that a decision made months ago now limits what you can do next.

Your interior designer can help you spend your budget wisely
A renovation budget has a habit of disappearing faster than expected. There are the obvious costs, such as builders, kitchens and bathrooms, but also lighting, flooring, decorating, window treatments, furniture, storage and all the finishing details that make a house feel complete.
It's not always possible to have everything you want (so annoying), so knowing where to invest and where to save becomes important. Should you spend more on bespoke joinery that solves a storage problem, or buy a freestanding alternative? Is that expensive tile worth the additional cost, or would a more affordable option achieve a similar result? Which existing pieces can be incorporated into the new scheme? One of my rules of thumb is that anything you touch daily (light switches/handles etc) is worth investing in. The internal carcass of a cupboard ... less so... (caveat as long as it's fit for the job)
An interior designer helps you look at these decisions in context, rather than making each purchase individually. This is also where a clear design plan can help you avoid buying things twice. The wrong-sized rug, a sofa that doesn't work with the layout or a finish that clashes with the rest of the scheme can all become expensive mistakes. No designer can promise that every project will run perfectly or that professional fees will always be offset by savings (although I try my best). But thoughtful planning, informed product selection and a clear understanding of your priorities can help you make better use of your budget. Also having someone narrow down the infinite choices out there as a starting poin can really help with design decision overwhelm too!
And remember, sometimes the best recommendation is not to buy something at all.

Who is going to manage the decisions and communicate with the trades?
If you've ever undertaken a renovation while working, looking after a family or simply trying to maintain some semblance of normal life, you'll know how much there is to organise. If you have yet to try it then please don't underestimate it - it's an extra job on top of your current life.
Builders need answers. Suppliers have lead times. Products arrive in the wrong finish. A decision about one part of the room affects another, and suddenly you're expected to make a choice by tomorrow that you haven't had time to think through.
This is where good communication and project management become just as important as the design itself. An interior designer can help communicate the design intent clearly, coordinate relevant information and liaise with architects, trades and suppliers to ensure everyone is aligned. Depending on the scope of the project, this may include specifications, drawings, product schedules, ordering, delivery coordination and installation.
The aim is to make sure everyone understands what is being delivered and how the different elements fit together.
My background in project management has taught me the value of planning, clear communication and anticipating problems before they become bigger ones. I bring that experience into my interior design work because I know that a good idea is only part of the job. It's also about helping the people involved understand the brief, keeping decisions moving and finding practical solutions when something doesn't go to plan. Communication is King.
The precise level of involvement will depend on the designer and the service you've agreed, so it's always worth clarifying who is responsible for what before work begins. For busy homeowners, having someone who can help manage the design decisions and coordinate the relevant details can make the renovation process considerably more manageable. The amount of clients who have said they are grateful that they are getting my support is growing and often we start as design only but as the project moves on the benefit of having me communicating across trades to ensure everything is correct becomes a must have too.
Tor has done a fabulous job working with me and my builder to design my new home, and I could not be more pleased with the results.
She was warm, friendly and supportive throughout the design and build process, while remaining calm, professional and solution focused during the few more challenging moments. She has a fantastic eye for detail, and I really felt that my needs were listened to, understood and then thoughtfully translated into the final design.
Communication was excellent from start to finish, both with myself and with the builder, which made the whole process feel much smoother and more collaborative.

The difference between a finished room and a finished home
When you're renovating, it's tempting to concentrate on the big, visible decisions: the kitchen, the flooring, the bathroom tiles and the paint colours. But a home rarely feels complete in isolation.
It's the way the spaces connect, the balance of colour throughout the house, the lighting that works for different times of day, the storage that makes everyday life easier and the furniture that feels right in proportion to the room. It's also about knowing when to introduce contrast, where to add character and when to leave negative space to let items sing.
This is particularly important if you're renovating in stages. Without a broader vision, you can end up with individual rooms that look lovely but don't quite belong together.
A cohesive interior design scheme doesn't mean every room needs to look the same. It means there is a sense of connection between them, whether through colour, materials, architectural details or the overall mood.
And while trends can be a useful source of inspiration, I believe a home should be designed around the people living in it, rather than the look that's currently everywhere. An interior designer can work with what you already have, those cherished items that have meaning to you, artwork you have collected (or suggest artwork you may like) and start to bring your personality into the rooms.
The aim is to create a home you'll continue to enjoy long after the renovation dust has settled.

So, is hiring an interior designer worth it?
I don't think every home improvement project needs an interior designer. If you're repainting a bedroom, replacing a few accessories or confidently updating a room you already understand, you may be perfectly happy doing it yourself. AI tools, Pinterest and online resources can be genuinely useful for exploring ideas and getting started. But if you're planning a major renovation, refurbishing several rooms or investing in a home you want to get right for the long term, professional interior design can offer much more than a collection of beautiful ideas.
It can help you:
Develop a design that reflects your personality and the way you live.
Make informed decisions about layout, colour, lighting, materials and furniture.
Create a cohesive scheme across multiple rooms.
Prioritise spending and reduce the risk of avoidable mistakes.
Plan decisions in the right order and understand how they affect one another.
Communicate the design clearly to trades and suppliers.
Manage the details that turn a design concept into a finished home.
Ultimately, the value of an interior designer isn't just in choosing the right sofa or finding the perfect shade of paint. It's in bringing all the decisions together, helping you navigate the process and creating a home that works as well as it looks. And AI? I'd see it as another tool in the design process, not something to dismiss. Use it to explore ideas, test a direction or help articulate what you like. Just remember that a convincing image isn't a guarantee that the design is practical, achievable or right for your home.
The real question isn't whether you can design your home yourself. It's whether you want to manage every decision, work out how they fit together and take responsibility for turning the ideas into reality.
A Home Renovation Checklist
I have written a practical guide to what needs deciding, and when which you can download from my website here.
Renovating a home involves hundreds of individual decisions, many of which affect something else. The key is to make the important decisions in the right order, so your design, budget and building work all work together.
As a taster here are the decisions most likely to cause problems if left too late:
Layout and furniture positions
These influence circulation, sockets, lighting, radiators, TV positions and storage.
Lighting and electrical plans
Decide these before walls and ceilings are closed up, and coordinate them with furniture, joinery and room use.
Kitchens, bathrooms and bespoke joinery
These often have long lead times and precise service, measurement and installation requirements.
Flooring and material transitions
Flooring build-up, thresholds and junctions can affect doors, cabinetry, stairs and the finish between rooms.
The full budget
The construction quote is only part of the overall cost. Fixtures, finishes, lighting, furniture, window treatments, delivery and installation all need to be considered.
Who is coordinating the decisions?
Establish who provides drawings, answers trade queries, approves changes, tracks orders and communicates delays before the work starts.
