Glass garden rooms are becoming more and more popular, and it is understandable. They expand your living area without the complete disturbance and expense of conventional extensions, fill up interiors with natural light, and make rooms that can be used throughout the year and that do not seem to be separate from your garden. However, they are not inexpensive and their acquisition implies serious choices. This is what you really need to know.
What Is a Glass Garden Room?
Glass garden room is basically a modern insulated building that is mainly composed of glass and is placed in your garden. Imagine it as evolution of conservatoires – they are meant to be cosy all the year round instead of overheating in summer and freezing in winter.
The most important distinction compared to conservatoires is good insulation. The contemporary garden rooms are insulated on the roof, have a double or triple glazing and are made to ensure that there are comfortable temperatures all year round. They are as though proper extensions and not seasonal spaces.
They are also unlike summerhouses that are more simple garden houses that are not well insulated or comfortable all year round. Garden rooms are built to thermal standards of house extensions.
The reasons why people prefer garden rooms to the traditional extensions.
The first appeal is usually cost. A good glass room could cost PS15,000-30,000 on size and specification. A similar extension would not take much more than PS30,000-50,000 or more when you include the groundworks, utilities, plastering, decorating, and all the other work that goes into it.
Disruption matters too. Conventional extensions take months to finish, and there is dust everywhere, temporary kitchens and overall mess. Garden rooms are constructed elsewhere or in your garden with installation normally taking 1-2 weeks. You do not live in a construction site.
In most instances, planning permission is easier. Garden rooms less than 2.5m high and other special requirements in this category are usually permitted development, that is, no planning application is required. Conventional extensions typically demand complete planning permission, which introduces time, cost and uncertainty.
Another significant factor is light. Garden rooms make the most of natural light, which traditional extensions fail to achieve. Glass on several sides to the floor and ceiling makes the spaces bright and airy that are entirely different in relation to brick extensions.
What Are You Gonna Do With Them?
Home offices are the most frequently used. Millions of people were forced to work at home during the pandemic, and spare bedrooms do not pass as permanent workstations. Garden rooms offer adequate segregation of work and home without having to travel more than a garden.
The detached nature of it also implies that video calls do not disrupt family life, and you can close the door on work at the end of the day – literally. The natural light and the views of the garden are much better than gazing at the bedroom walls. It is possible to equip good office furniture, equipment and set-up without interfering with home spaces.
Long stay accommodation is also in demand. It may be that your living room is too small and you need a place where teenagers can hang out but not in their bedrooms or your living room. Garden rooms will offer additional reception area that does not seem crowded into your current home.
Garden rooms are excellent locations of home gyms. The noise and equipment remain independent of living spaces. Exercising is more enjoyable with natural lighting as compared to basement gyms. The ventilation is not as difficult as with converted garages. And you can listen to music or work out DVDs without irritating other members of the family.
Garden room locations are useful in art studios, music rooms, craft rooms, and hobby rooms. Artistic activities require special space and proper light and it is easy to maintain a separate mess rather than co-locating it with the main houses. Natural light is especially of significance to visual arts.
Entertainment areas or garden bars would make social areas that are independent of your primary house. Make noise, host friends, and not to think about how to break bedtime habits and early mornings. Others are fitted with bars, pool tables, or cinema-style seats.
Design Choices and Specifications.
The size is not as trivial as it sounds. Garden rooms smaller than 10 square metres are cramped: only storage can fit in. 12-15 square metres is enough to fit home offices or small studios. 18-20 square metres is enough to accommodate proper furniture arrangements. 25+ square metres is significant additional living space.
Measure your intended uses. Surprisingly large space is required by office desks, chairs and files. Gym equipment is bulky. Lounge furniture must have space to breathe. Do not make choices using blank floor plans, visualise furniture.
The choice of roofs has a considerable impact on performance and aesthetic. Glass roofs are the most efficient in light and sightseeing, but they may be overheated in summer and lose heat in winter even with modern finishes. Lantern roofs Lantern roofs are solid insulated with glass areas which balance light and thermal performance. Solid insulated roofs with skylights are the most thermal efficient and less dramatic in their light.
Wall designs are either fully glazed on all sides or predominantly solid with big windows. Additional glass implies additional light and connexion with the garden but it may also imply additional heat loss and lack of privacy. Think about which sides have neighbours, angles of the sun and what you really want to see.
The door options influence the utilisation of spaces. Bi-fold doors open up expansive spaces that break down the boundary between indoors and outdoors – brilliant during summer but they close up into rooms taking away space that could be used on wall space. Sliding doors are less messy yet do not open so wide. French doors are conventional and less space consuming but open up narrow gaps.
Frame materials are either aluminium or uPVC. Aluminium provides thinner frames with greater glass, is more modern, and is available in large colour choices including wood-effect. It is also pricier but usually the option of choice in terms of quality garden room. uPVC is cheaper yet heavier and less aesthetic.
The Thermal Performance Question.
This is crucial. Garden rooms should ensure that you are comfortable throughout the year or they will turn out to be costly shed like counterparts that you hardly use.
The specification of glazing is very important. Minimum requirement is that of double glazing. Triple glazing is superior in thermal performance and heavier and costlier. Low-E coating minimises the heat loss. Solar control glass is used to avoid overheating. Insulation is enhanced by the use of argon or krypton gas-filled units.
Insulation of the roof is essential since it increases the heat. The rooms are made comfortable with specifications such as 100mm insulation with U-values of about 0.15-0.18 W/m2K. Here the cheaper garden rooms economise and you will find it.
The heating can be extended house central heating, when garden rooms are not too far, electric radiators or under floor heating, or air source heat pumps in bigger rooms. The difference between running costs is substantial – underfloor heating is cheap, electric radiators are convenient but more expensive to operate.
Summer overheating is avoided by means of cooling and ventilation. Cross-ventilation is provided by opening windows on more than one side. Roof vents release hot air. Direct sun is minimised by blinds or shading. It can be air-conditioned, which is costly and connotes a failure in design.
Planning Permission Building Regulations.
A large number of garden rooms are considered permitted development, which does not require planning permission. The regulations are particular however:
Building height 2.5m within 2m of boundaries, 4m above that.
Covering not more than half of garden area.
Not to extend past main house front wall.
Single storey only
Boundary minimum distance requirements.
Most buildings in conservation areas and listed buildings have various regulations that mandate planning permission. Always enquire with local planning authorities prior to assuming that permitted development is applicable.
Building regulations do not relate to planning permission. Garden rooms that are less than 15 square metres and are more than 1m away from boundaries and have no sleeping accommodation do not generally need approval of building regulations. The larger structures or those with other designs require approval of structural integrity, fire safety, drainage, and electrical work.
Frankly speaking, this is tricky enough to be advisable with the assistance of a professional. Good garden room firms are the ones who will advise you on what you need and submit applications.
Prerequisites and Preparation.
Garden rooms should have good foundations. The type is based on the conditions of the ground, the size of the room, and the designing. Options include:
Smaller rooms on solid ground have concrete slab foundations. They are comparatively simple and inexpensive. Ground screws are becoming very popular – steel screws that are drilled deep into the ground offer stable bases with reduced groundwork and quicker installation. They are appropriate in most types of soil and can be removed when necessary.
Piled foundations are used in trying to work on a hard ground or in a bigger structure. They cost more and yet they are needed. Strip foundations are appropriate in huge garden rooms constructed to accommodate extension standards.
Ground preparation matters. Level sites are simpler. Sloping gardens require additional ground work. Before installation, poor drainage should be addressed. The foundation stability should take into consideration the trees and their root systems.
Installation is influenced by access to your garden. The majority of garden rooms are delivered in parts that have fair access to the delivery trucks and machines. Extremely limited access could imply smaller sizes, hand-loading or crane delivery – which are more expensive.
Utilities and Connections
Electricity is needed in lighting, heating and power sockets. Installation of cables to have your garden room requires qualified electricians. Armoured cable is underground. Protection by circuit breakers and suitable earthing cannot be compromised.
The cost is added to distance between house and garden room and obstacles that have to be dug through. Budget PS500-1500+ based on complexity. There are companies that involve simple electrical installation, and other companies charge separately.
Plumbing will not always be needed, but handy in case you would like to have sinks, toilets, or kitchenette. Underground running water and waste pipes need more serious groundwork. Additional consideration is heating of pipes during winter. A lot of garden offices do not have plumbing but garden bars or guest areas usually do.
Home offices are concerned with internet connectivity. WiFi extenders operate provided that the signals are sufficiently strong. Ethernet cables are underground and offer good connexions. Mesh WiFi systems are used in gardens that have weak signals.
Extensions of house systems or independent lines may be used where necessary to make phone calls.
Costs and What Affects Them
Small, simple buildings begin at PS10, 000-15,000. They are used as simple storage or infrequent use but tend to be not thermally as good as comfortable year-round use.
Decent quality, well insulated 12-18 square metre mid-range garden rooms cost PS15,000-25,000. It is the place where the majority of individuals arrive to have their functional home offices or studios.
Premium garden rooms are over PS30,000-40,000+ larger building, high spec glazing, high end finishes, or complicated designs. These are modular quality house-extension.
The evident cost driver is size. Bigger buildings consume more materials and require more time to instal. Specification is also a big issue. Triple glazing is twice as costly. Aluminium frames are higher than uPVC. There are integrated blinds, smart glass, and luxury finishes which are cost incremental.
The base and foundations depend on the ground conditions. Difficult sites cost more. Installation of the utilities is based on distances and complexity. Final construction such as external decking, gardens surrounding garden rooms and interior fit-out is a cost that increases the overall project costs.
Choosing a Supplier
It is not the same thing as purchasing furniture you are spending serious money on a building that you are going to spend decades of your life. The selection of the supplier is critical.
Established firms that have a track record are more secure. Search to find companies that are several years old, have a permanent location and are financially stable. There are garden room cowboys, and you would rather not be in the middle of the project when they are gone.
Visit showrooms if possible. The sight and experience of real garden rooms are very helpful. Inspect the quality of cheque builds, feel door and window mechanisms, evaluate thermal performance, and determine whether marketing is identical to reality.
Past customer reviews and testimonials give an insight. Go beyond company websites to review sites. Request customer references whom you can call. Decent companies will not be reluctant to offer these.
Warranties and guarantees represent trust in goods. Seek at least 10 years structural guarantees and reasonable glazing guarantees. Know what is and what is not.
Full quotes must cover all that is contained in it foundations, base, structure, glazing, doors, windows, electrics, insulation, internal finishes, installation and VAT. Indistinct quotes create issues in the future whereby extras emerge.
Installation Schedule and procedure.
Average planning and design would take 2-4 weeks after selecting a supplier. This includes site surveys, finalising specifications, and coming up with detailed plans.
The time spent in manufacturing is 6-12 weeks based on the capacity of the suppliers and the complexity of the design. Custom designs are more time consuming than standard designs. Delays can be brought about by supply chain problems.
The preparation of the site may require days or a week based on the complexity of groundwork. Garden room installation requires foundations to cure.
The real installation typically takes 1-2 weeks on the usual garden rooms. Difficult sites or complex designs are more time-consuming. The building comes in parts and is assembled on-site and equipped with electrics, insulation, and finishes.
Snagging and finishing could require several days. This includes changes, cleaning, and making sure that everything is fine.
Overall order to completion time is normally 12-16 weeks. There are companies that are quicker and those that are slower. Set achievable timelines and provide cushion against the unavoidable delays.
Living With Your Garden Room
The maintenance is minimal but not zero. There are cheques of seals, drainage, and mechanisms every year to ensure that things are fine. Washing glass keeps up the outlook and light penetration. Leaves do not block the cheque roof drainage.
Condensation may take place when there is poor ventilation or lack of heating. This means that there are issues that require solutions and not necessarily inevitable. Good garden rooms should not experience chronic cases of condensation.
The insurance should be revised to include garden rooms as permanent buildings. They contribute to the value of property and should be safeguarded. Garden buildings are automatically covered by some house insurance policies up to some values, whereas others need to be added.
The security factor also involves locking of doors and windows, alarm systems when valuable equipment is kept in the premises and external lighting. Garden rooms are more susceptible than houses that are just distinct and easier to access.
The usage tends to change with time. When the working conditions are altered, the home offices transform into guest rooms. The play ground of the children is turned into teen dens. Inherent flexibility will make garden rooms useful with the need change.
Glass Garden Room? Could it be the Right One?
They are genius solutions to most cases but not the solution to all space problems.
Garden rooms are good in case you have the space in the garden, and you require more functional room and not only additional storage, you want the natural light and connexion to the garden, and you want to have the installation that is less disruptive and faster than the usual extensions.
They are not so well adapted when your garden is small and you have no reasonable place to put it, when you have planning constraints, when you are only interested in storage and when you cannot afford reasonable specifications to give you year-round comfort.
Other possibilities to consider would be traditional extensions (more permanent, perhaps better integrated), conservatories (less expensive although thermal performance problems), garden studios/summerhouses (less expensive but not a year-round comfortable space), or even reorganising existing house space.
The finest garden rooms literally expand your life and your work. They furnish spaces which are used every day, not occasionally. They do not make costly garden decorations but actually solve real problems. They also strike a balance between cost and quality to provide long-term value.
Research, research, research, get some quotes, visit showrooms, and know what you are actually purchasing. A good glass garden room is an investment in property and living. An inexpensive one that fails to work is costly to regret that you will see each time you look through the window.
