Changing the look of one room or the whole house? Do it in style with Onyx Interior Design

Welcome to Onyx Interior Design


The fabulous Onyx Interior Design was founded by Carol Cottrell in 2006 following her return to the UK from Los Angeles. Whilst in LA, Carol completed her interior design qualifications and worked with a prominent and highly sought after interior designer. During this time, Carol project-managed numerous house renovations as well as multifaceted restorations which armed her with the perfect background to launch her own company on return to Gerrards Cross.


Since the launch of Onyx Interior Design, Carol has been welcomed into the homes and hearts of local people. The secret of her success is the gift of really listening to her clients and in turn creating the design they want within the space they have; making sure that all the work reflects the client's individual taste and style and is delivered on time and within budget.


With many years experience, Carol ensures that Onyx Interior Design delivers quality on every one of its projects whether it is the conversion of one room; an entire renovation; being involved from the beginning of a new build working with architects and builders; or helping change the feel of a room with lighting or soft furnishings. Using the best tradesmen enables Onyx to deliver exceptional interior design based on the combination of the client's ideas, needs and space and of course, budget.


Space Planning


To avoid unnecessary waste of both time and money requires skilful planning at the outset. Working closely with you, Onyx will ensure you identify exactly what you need and want from your home and then Carol will produce scale drawings, 3D drawings and colour boards so that you can really envisage as well as feel what the end result will be.


Architects and Builders


Onyx can assist you by working alongside your architect and builder and act as your liaison between all parties. Alternatively, Onyx can project manage the complete development on your behalf. Having Onyx on board at the advance planning stage will ensure you have someone who will give their full attention to all the details thereby avoiding expensive mistakes and omissions and ultimately saving money.


Kitchens and Bathrooms


Whatever you do in the kitchen - whether you are a cordon bleu chef, home-grown cook or simply there to enjoy the ambience food creates - a well designed out kitchen will enable you to make the most of what is singularly the most expensive purchase for your home. With Onyx on board the hub of the home will be crafted to suit your individual family and cooking needs.


Bathrooms can be a splashy pool for children and toys or a quiet haven for you to relax in at the end of the day. Onyx will create a bathroom that will unite all your individual needs, helping you to choose from the fabulous array of designs and innovations. Once you select new tiles, handles and finishes it will transform your bathroom beyond belief.


Soft Furnishings & Window Treatments


It is remarkable how a room can be transformed with the addition or replacement of soft furnishings and/or window treatments. Onyx Interior Design can design and supply window treatments to flatter your windows whether you are looking for fabulous hand-made curtains, roller blinds, or cascade shutters.


To complement the look, Onyx has a wide range of designer fabrics - from contemporary to traditional - for you to select from and which can be used for bedspreads, cushions and headboards.


Upholstery and Furniture


Whether you are looking for bespoke furniture or have a favourite piece of furniture you want to re-cover, Onyx will help you to find the look that meets all your requirements and ensure that it fits the space and suits the setting.




Often not thought of until quite late on, but if factored in early, lighting will undoubtedly bring a different dimension to each of your rooms. Onyx will expertly guide you whether you are looking for zoned or standard lighting.


Designing for older people


Carol also has expertise in designing properties for the elderly, dementia and Alzheimer's sufferers enabling them to live life more easily.
