Our garden rooms are designed with your comfort in mind, ensuring they are fully insulated and suitable for year-round use. Every design is meticulously crafted by our resident carpenter, Luke, who brings your vision to life. At Haywards Carpentry, we understand that one size doesn’t fit all, which is why our garden rooms are entirely customisable. You can choose from various options, including sound insulation for a peaceful environment, durable GRP roofs for longevity, premium flooring for a polished look, high-quality doors for security, and energy-efficient double glazing to keep your space comfortable.

The benefits of a bespoke garden room are numerous. Not only does it provide a functional and versatile extension to your home, but it also adds value to your property. It’s a cost-effective way to expand your living space without the need for a traditional home extension, and it can be tailored to match your unique style and requirements.

Garden room questions

Below is a selection of frequently asked questions regarding our garden rooms. If you have any additional questions, please don’t hesitate to get in touch.  

Garden Rooms are considered to be permitted development, not requiring an application for planning permission*, provided all the following conditions are met. At Hayward’s Carpentry, we will collaborate with you to ensure all the criteria are satisfied:

  • Garden Rooms must be single storey with a maximum eaves height of 2.5 metres and a maximum overall height of 4 metres with a dual pitched roof, or 3 metres in any other case.
  • If the Garden Room is within 2 metres of the property boundary, the entire structure should not exceed 2.5 metres in height.
  • You can utilise up to 50% of the area of your entire garden.
  • The area of your garden encompasses all your land, excluding the area occupied by the house. This area includes the front garden, side gardens, and back garden, minus the space occupied by any other structures, fuel tanks, etc.
  • No buildings are permitted in front of the front elevation of the house.
  • In conservation areas, construction is restricted to the rear garden; no structures can be placed at the front or side.
  • For listed buildings, full planning permission is required.
  • In Areas of Outstanding Natural Beauty, the maximum size allowed is 10 square meters, and it should be located at least 20 meters away from the house.
  • Any new building must not serve as separate, self-contained living accommodation and must not feature a microwave antenna.

*If your garden room requires planning permission (if it does not meet the above criteria), we are pleased to offer a comprehensive planning service, covering everything from design to the submission of a planning application.

Investing in the right garden room not only ensures a lifetime of utility but also enhances the worth of your residence.

Estate Agents determine property valuations by considering the total floor space of habitable accommodation within the plot’s boundaries. As every Hayward’s Carpentry Garden Room is accompanied by a building regulations certificate, it is classified as habitable space.

For example:

In 2018, the mean cost of property sales in Greater London stood at £5,131 per square meter. Therefore, if you were to construct a 20sqm garden room, it would contribute £102,620 to the overall value of your home.

Structural Insulated Panels (SIPs) surpass alternative construction methods across nearly all thermal and structural aspects due to the fact that insulation is an integral part of the system, not an appended feature. Consequently, SIPs exhibit outstanding thermal efficiency and u-values, resulting in a substantial reduction in your heating and energy expenses, establishing SIPs as a genuinely eco-friendly choice.

We collaborate with building control to guarantee the installation of appropriate foundations for your garden room, considering factors such as soil conditions, garden slope, and tree proximity.

Subsequently, we engineer foundations that minimise disruption to your garden and the surrounding environment, ensuring approval by the building control inspector.

Certainly, we provide a diverse selection of aluminium and uPVC doors available in three stylish colours: white, black, and anthracite grey. Our door styles include bifold, sliding, or French doors, all of which are equipped with energy-rated double glazing as the standard feature. Additionally, we offer side windows in both full height and letterbox window options to cater to your specific preferences.

We have different types of flooring for you to choose from. Our regular choice is laminate flooring, which is simple and practical. For those seeking a touch of luxury, we also offer the choice to upgrade to either luxury vinyl flooring or a stylish tiled floor. We have samples available so you can pick the one that suits your style best.

We apply foil-backed plasterboard, which will be plastered and smoothed to give a neat finish.

We also offer the option to professionally paint the interior walls white. Additionally, if you’d like to add a pop of colour, we can paint one wall in a feature colour to create a stylish accent.

At Hayward’s Carpentry, our team comprises certified electricians who handle the complete electrical setup, including wiring, lighting, switches, Coax, and Cat 6 cables. We ensure a thorough testing of the electrical installation and provide you with an electrical certificate once your garden room is successfully completed.

Our typical garden room construction time at Haywards Carpentry is ten working days, though this duration may vary depending on any additional services you might need. Since we use structurally insulated panels for our garden rooms, the actual building phase is generally swift and straightforward.

For larger and more complex garden room projects, which may involve tasks like plumbing for bathrooms or kitchens, as well as electrical and media installations, a custom timeline will be necessary.

Many of our clients opt to have their garden landscaped or add paving after the garden room construction, which will also extend the project timeline.

Why not schedule a complimentary site survey with Luke Hayward? We can walk you through the entire process, offer a quote, and provide you with an estimate of the project’s timeline.
