The Garage, and Unused Space

When most people consider extending their home in some way, they don’t consider that the garage could be the best way to do this. A high quality garage conversion can provide you with a perfect solution to any space issues that you may have within your current property.

Are you really using your garage for anything important?

Over recent years it has become progressively more difficult to store large cars or vehicles in our properties.  Some years ago most people used to simply use the garage for storing their car. Modern car design has meant that garage parking is now not really necessary. By storing rubbish and unwanted items in your garage, you are essentially wasting what could be a beautiful addition to your living space.

Most people’s garage space contains items that they stored many years ago and have never found the time or motivation to remove. As we generally need living space more than we need storage space, we are often overlooking a very cost-effective and simple way to enlarge our home.

Will the Addition of a Garage Conversion Add Value to my Property?

A garage conversion could add up to 20% to your homes value in Portsmouth, while gaining valuable extra living space that is less prone to complications planning. So if the project cost is less than the added value to your land, this works out as a cost-effective way to add more rooms.

Portsmouth planning permission and garage conversions

For many garage conversions especially integral or attached spaces most of the work is in-house (except the changing the front and installing one or two windows).

Garage Conversions

As the majority of garage conversions are considered permitted developments or pd, it is not necessary to request planning consents in Portsmouth. It is highly recommended to check your house deeds to see if your house is subject to any restrictive covenants which only allow your garage to be used as a parking area because if that is the case they will need to be discharged. Most properties in Portsmouth will require written formal approval if you plan to alter the use of your detached garage.

By putting together any design sketches and asking for approval from householder planning, you will still be able to convert your garage even if your pd rights have been revoked. There would be a charge of £500, plus design fees. If you want to drastically alter the exterior appearance, such as making major changes to the windows, using new materials, or incorporating an extension, a complete application would also be required If you have adjacent neighbours or you reside in a listed building it could be that you will require listed building consents or party wall agreements to undertake a conversion.

Portsmouth building regulations and converting your garage

As your garage conversion will allow you to use your garage in a different way, it would then be subject to the building regulations When beginning complex Portsmouth garage conversions, our first class design team highly recommend drawing up structural plans before the project begins.

As long as the conversion is built according to the approved schematics of your structural plans, you can rest assured that the conversion is conforming to building regulations. By inspecting the key areas of the conversion construction a building control officer or authorised inspector can provide additional assurance that key areas such as ventilation, insulation and energy conservation, fire safety (including escape routes), are all built to conform with the building regulations.

High-quality garage conversion key works and considerations in Portsmouth

To prepare any garage for a conversion, the first step is to make sure that the walls and roof are completely sound and watertight. Our first class team of builders and tradespeople will then conduct the majority of the conversion work inside the existing garage.

There are sometimes unforeseen problems at the beginning of a conversion such as patchy foundations or issues with internal walls, this is difficult to assess until the main structure has been stripped back, which is the first task for our team. Here is a summary of the construction work required for your conversion

  Evaluating the existing floor

The concrete floor in garages, are generally built to be sturdy enough for regular domestic use. However, concrete floors often make the room to cold so it may be necessary to level them, damp proof them with an acceptable membrane, and insulate them to increase the temperature and retain heat within the conversion. Because the floors of garages are often lower than the floors in the main house, insulating them in a variety of ways is often quite straightforward and will simply raise the level of the garage floor to meet that of the main house.

Building work to convert a basement

The first thing when converting a basement is to ensure that the foundation will not let in water. Basements can be affected by rising groundwater therefore it is very important to ensure that your basement is built up to the maximum height of the area. In theory, in a regulated drainage system, a cavity drain membrane system allows moisture of flowing water to pass behind the cone. The installation of a cavity drain system generally requires very little planning or destruction to your property.

  • Should I infill the door?

    The most popular route is to replace the main garage door with traditional walling matching the rest of the house, such as a masonry infill completely to and bonded into the existing brickwork. It is very important that the foundations of your garage can withstand the extra weight of the conversion, we will assess this thoroughly during the design stage. Our innovative team of designers will carefully assist you to, for example add windows or a glazed access door to the conversion which can increase the natural light in the room and also lighten the load placed on the foundations.

  • Do I need to insulate the walls?

    Our team of dedicated industry professionals will be able to advise you as to whether you need to insulate the walls of your garage, however, this will generally not be necessary in an integrated garage for example. If your property has an attached or detached single skin garage, our dedicated team of tradesmen can erect a stud wall inside the garage, allowing it to be insulated internally. Buildings with cavity walls may have insulation blown into the gap, thereby preserving the space of the internal floor.

How do you insulate roofs?

It is a very simple process for our skilled builders to remove the garage roof at loft level. By insulating a roof at the rafter level, we can create a warm roof system in which we would also generally use rooflights.

In order to prevent condensation, flat roofs must be equipped with rigid insulation between and under the ceiling joists, with a ventilation gap above. It is very important to maintain the original height of the room that is being converted, and we achieve this by using the latest in slim multi-foil or polysocianyiltrate (pir) products.

Garage Conversions

Windows and doors

The fenestration you choose will have to hit the appropriate full unit u values (1.6 w m2 k for windows, 1.84 doors), meet your safety standards, provide sufficient ventilation, and suit your home style. We would also recommend the cost-effective option of operating regular units. Our sophisticated engineering techniques involve punching a suitable hole and inserting lintels to ensure the installation of casements, door sets and sashes to the highest standard.

The main house and garage openings can also be installed using the same method. One of our ingenious design techniques involves using a reinforced steel beam over a larger span to create a modern, spacious and open plan feel to your conversion. One of our specialist structural engineers may need to make the calculations for this kind of design. Be aware of the possibility that if you have an integrated garage there may be restrictive agreements imposed by a developer which will have to be purchased before the conversion can take place.

If you’re building a habitable room that doesn’t have an exterior door, directly secured path, or its own door leading to the outside, then you have to have an escape window. Our dedicated team of professionals can guarantee that any escape window fitted will comply precisely with industry and safety regulations.

Garage Conversions

Installing heating and electrics

We would always suggest employing trained professionals to install any kind of heating and electrics infrastructure and to require them to self-certify their work under part p of the building regulations. Your consumer unit and boiler may have to deal with an additional load due to the addition of new electrical circuits and heating loops in the conversion.

It is wise to note that an upgrade of your boiler or consumer units could result in £2000 extra being added to the final cost. For a new ceiling structure in a quality garage conversion we would suggest the use of led downlights to illuminate the room effectively. Why not consider installing cutting-edge underfloor heating to maximise the interior space in your new conversion?

If you are planning a kitchen or bathroom, the hot and cold water sources as well as drainage would need to be accounted for. Ventilation could be an issue. Opening windows, fitted with trickle vents, will be sufficient in most cases but if you incorporate a bathroom or kitchen, you will need a powerful enough extractor ventilator to manage the buildup of humidity.
