A Closer Look at Our
Construction Services

New Builds

Onyx Groundworks & Landscaping undertakes new build property developments of various sizes in the domestic sector. From the architectural design to the planning submission and physical build, our experienced team understands the importance of working to strict schedules and project sign-offs.

Liaising closely with building design experts and architects enables the provision of clear, realistic development timescales. This allows us to complete all new build properties in Farnham, Guildford, Leatherhead and the surrounding areas on time and within budget.

With decades of experience in the building trade, our skilled tradesmen and engineers work just as efficiently as a singular contractor as we do alongside other property development companies on large-scale, bespoke projects.

Home Extensions

Our company has successfully managed a large number of property extensions and conversions to completion. As such, Onyx Groundworks & Landscaping takes great pride in offering a comprehensive service for converting spaces or adding a home extension.

By listening to your design preferences and unique requirements, we ensure smooth project development from the outset. Be it a conversion, single-storey extension or double-storey addition, our team of experienced builders completes all work to the strictest standards. We have the skillset to create rooms of any type too, be it an office, bedroom or en-suite bathroom.

Because we manage your build from start to finish, one of our qualified and time-served Project Managers happily schedules a free site visit to assess the size and type of property extension or conversion you want us to undertake. With the required information, we then offer a written, no-obligation quote for your consideration.

Refurbishment and Renovation

At Onyx Groundworks & Landscaping, we provide the complete service package for home renovations. This includes demolition and waste removal, replacement walls and floors, ceilings, partitions, plastering, doors, windows, re-fitting kitchens and bathrooms, tiling, painting, electrics and plumbing.

We can rebuild practically anything you need to an exact specification. Simply tell us what you want, or our personnel can offer advice on what we think would work best for your specific requirements.

Within offices and workplaces, as with homes, we also offer the complete service for refurbishments. This includes permanent or relocatable partitions, cubicle partitions, replacement suspended ceilings, carpet and vinyl flooring, kitchen units with worktops, toilet refurbishment – including vanity units, and service concealment panelling. From Farnham to Guildford to Leatherhead, we cover office refurbishments across Hampshire, Surrey and West Sussex.

Our team offers all the renovation services covered above with office/workplace refurbishments. Whatever your demands, however big or small, Onyx Groundworks & Landscaping can help you.


Our company is the natural choice to build your porch in Hampshire, Surrey or West Sussex.

We recognise the importance of your home’s unique features and character. You can rely on us to design and build a porch of unmatched quality. Your new porch provides an extra layer of security at your front door, and all while saving you energy with added insulation.

We offer a complete service, from base building and brickwork to the fitting of a superior door, windows and roof. Your satisfaction means everything to us, so you can rest assured – we create an attractive porch that fits seamlessly with, and complements, your original house.


A new conservatory, glazed extension, orangery or conservatory roof replacement can reinvent your home’s appearance and functionality. You can create a space to focus on your hobbies, a second living room or a perfect transition between your house and garden. Regardless of your intended purpose, Onyx Groundworks & Landscaping builds a conservatory tailored around your requirements. Each of our conservatory installations ends in the same result: an exceptionally stylish, high-performance addition that’s built to last.

Bespoke Outbuildings

Our company can build garages, sheds or workshops to suit your home. We have vast experience using a varied range of materials, such as timber and concrete. Our team has the flexibility and know-how to build your garage or outbuilding to exacting standards, and all with a friendly, professional service. Whether you just want a basic shed, single garage or you want a much larger construction with a room above, Onyx Groundworks and Landscaping can help you unlock your property’s potential.
