Why Choose a 5m x 4m Garden Room?

These buildings have become more popular in recent years for several reasons:

Working from home
With the rise in remote work, many individuals face specific challenges when trying to maintain productivity at home. The noise from children playing or the discomfort of working on a dining table can lead to distractions and physical discomfort. More and more people are working from home full-time or part-time, so they need a dedicated workspace. A garden office provides a quiet, comfortable space away from the hustle and bustle of the heart of the house while also freeing up room indoors.

Versatile options
These units are versatile and flexible. They can be used as offices, teenage hangouts and dens, garden bars, art and design studios, home gyms, dance and yoga studios or tranquil retreats designed to induce calm and relaxation.

Provides an alternative to moving
Studies show that Brits are increasingly likely to renovate and update their homes rather than move house. Adding a room in the garden is a brilliant way to increase living space and cater to modern lifestyles for those who don’t want to move.

How to Choose the Perfect Building

A dazzling array of garden rooms and offices is available, so how do you narrow down the options? If you’re thinking about buying one for your home, here are some essential considerations:

2. Function: What do you plan to use the building for? Is there a specific purpose, or are you hoping to create a versatile, multi-functional space?

3. Budget: The cost of these buildings varies. Set a budget before you start visiting showrooms and searching online.

FAQs For Garden Room Sizes

  • How Long Does Delivery Take?
    Delivery times vary throughout the year, typically ranging from 4 to 12 weeks. For the most up-to-date information, please visit our dedicated delivery page.

    If you have a specific date in mind for your order, let us know. We are always happy to do everything we can to meet your needs.
  • How Long Does Installation Normally Take?
    If your foundation is ready before we start, most buildings can be put together in just one day, depending on the size of your project.

    We take care of the design, preparation, and delivery of all materials ahead of time to make sure everything goes smoothly. This way, we can install your building quickly and with as little disruption as possible.

    We can also arrange the construction of your base as well as other ancillary services.
  • How Long Will My New Building Last?
    How long it lasts depends on things like the materials your building is made from, how well you take care of it, and what kind of weather it faces.

    Taking good care of your garden room and keeping up with maintenance will help it last longer. Bad weather and neglect can make it wear out faster. Building it well and choosing strong materials also helps it stay in good shape.

    Check your buildings regularly and fix any problems right away to help it last. Using pressure-treated timber is also a smart choice, as is StrongCore Cladding

    You can see some guidelines on this page.
  • What Specific Bespoke Options are Available?
    Whether you need a taller garden room, extra or fewer windows, or doors and windows moved, we can do that for you. To start a custom order, simply contact us to discuss your specific needs and preferences. Once we understand what you want, we’ll give you a clear plan and price. Our team will guide you through every step to keep things simple. It usually takes 6 to 12 weeks to build and deliver your new building, and we’ll keep you updated throughout. We’re committed to working hard and providing you with great service as we build the garden office room you’ve always wanted. Make sure you get the right building for you and your family. Give us a call at (01483) 237550 or stop by our showroom to talk about what you need. We’re happy to give you a quote with no pressure.
