As you're working with the existing construction you won't necessarily need to dig out new footings. It is always worth getting the existing footings checked out though, especially if you want to build a second storey on top of the garage at a later date.
"If you're working with an attached garage, removing the dividing walls tin add a pregnant amount of space to the nearly lived-in areas of your domicile," says Sabatino Torchitti, head of quality in Building Regulations at architectural practise Resi.
Carrying out a garage conversion makes good sense if yous're undertaking a larger house remodel at the same time. That way, you can rejig the floorplan to establish a layout that flows from one zone to the adjacent. Be aware though, that borer a wall and hearing a hollow sound isn't necessarily proof that it's non load begetting. If you lot're unsure, information technology'south worth bringing in a structural engineer to check.
Is My Garage Suitable for Conversion?
Before moving alee, there are however numerous considerations to factor in, especially if the scheme is to deliver the results you want. "You'll need to consider how the garage is constructed and what you lot want to use it for," says Jude Tugman, managing director at Builder Your Home. "These criteria will impact on the cost of the conversion."
Practise you lot want more light, a quiet study, a utility surface area or an extra chamber? Additionally, if you're doing away with your main storage infinite for bikes and tools, you'll need to work out where these items can exist moved to.

- Remember that you will be held responsible for the legality of work done on your property. Time and energy will be required supervising work, beingness present to permit tradespeople admission and making design and other decisions
- Will planning permission be granted? Is the firm listed or in a designated area?
- Might the price of reinforcing foundations, a new roof etc. mean you are paying more than you expected?
Volition I Demand to Replace the Garage Roof During a Conversion?
If, on inspection, you see that water is lying in pools on the flat roof, so this has the potential to crusade bug in the new space below. The roof will need repairing and the underlying cloth of the structure checking for impairment.

This could hands rising to between £1,500 and £2,000/m2 depending on the level of work and the terminate you choose.
"For a unmarried garage conversion, you'll demand to budget around £20,000, with some variation due to your choice of materials and fittings," says Rob Forest, managing director at Simply Extend. "For a double garage, that effigy would be more than similar £thirty,000."
Of class, at that place are caveats for all these prices. Project costs will vary depending on structural changes, utilities and plumbing, which tin push prices up (and if your project is in London you should always expect to pay at the elevation end of the range).
It'due south also worth noting that at nowadays construction material shortages are causing a spike in many building materials, from timber and steel to plaster. In fact, some estimates suggest that building quotes take increased 10% twelvemonth on year to factor in these increases, besides as an increased workload for builders overwhelmed with new demand and less bachelor labour. Y'all should look to wait several months before a contractor can start your garage conversion at present — you may notice in that location'southward a practiced reason a builder has an firsthand availability, and that they're a company to avoid.
Other factors will affect the overall cost of your conversion, from the condition of the existing construction to the fit-out spec and level of terminate. If the foundations, walls or roof are in questionable condition before works get started, the cost of putting them right could potentially result in a bigger outlay than you budgeted for.

- blueprint fees
- planning applications
- the services of a structural engineer.
Pattern
Do I Demand an Architect For a Garage Conversion?

Using an architect, an architectural technologist or another type of pattern professional volition mean skillful design input and ideas that you lot might not have thought of. A design professional will also have useful merchandise contacts and will take experience in dealing with Building Control.
When it comes to architect costs, expect to pay from as petty as £one,200 right up to £iii,000 for design fees, depending on the complication of the pattern.
Some people choose to come up up with a design themselves and carry out a DIY garage conversion — a adept option for those with limited funds and the spare time to get stuck in.

This is well worth thinking about every bit a way of gaining actress first floor space without increasing the overall footprint of the house.
Clearly, creating a double storey extension means more work and expense, merely the cease value of the house should brand it worthwhile. The existing foundations will almost certainly need to exist checked and upgraded, and in that location will be further Building Regulations to consider. For instance, the garage ceiling and new floor in the upstairs space will accept to achieve a minimum of 30 minutes fire resistance.
Additionally, at that place will be thermal and sound insulating considerations to take into account.
How practise I Brand a Garage Conversion Look Seamless?
Ideally you want to make your garage conversion wait like part of the rest of your firm, as opposed to a converted garage. This should exist something you tin can work on with your chosen designer.
One exception is in the case of partial garage conversions. This is where the front end of the garage remains unchanged both internally and externally, while the rear section of the garage is incorporated into the house. This allows yous to retain some storage space, while gaining a lilliputian extra living space — perfect for those after a utility room, a fiddling actress kitchen space or a playroom.
Ensuring the materials used for the cladding and roof (where there is one) match or necktie-in with those on the main business firm ensures a seamless finish, as does matching the window and door style.
Alternatively, you might wish to adopt a contemporary take on the pattern and highlight the garage as a new element of the house, choosing a modernistic cladding or render.
A new cladding will overcome any bug sur- rounding how the old opening for the garage door is curtained — a badly bricked up opening is a definite no no.
Building Regulations

A edifice notice or full plans application will demand to exist submitted to building command equally role of this process. Your local building control department will and then register the conversion and carry out inspections throughout the projection, then outcome the concluding certificate on completion.
Do All Garage Conversions Need Windows?
Garages don't always open up onto hallways, and if this is the case for your build, y'all may be required to install a window that acts equally a fire escape road under Building Regulations. This window is subject to sure criteria, including its height from the flooring, how information technology opens and the size of the openable section:
- Width and peak no less than 450mm
- Maximum 1100mm from the flooring level
- Openable area of 0.33m2 at the bottom of the window
- More often than not side hung windows are required
If your garage conversion opens straight onto a hallway providing a direct protected route to an external door, or has access to the exterior from within the garage, the window won't be required.
Carry in mind, windows within garage conversions under Permitted Development are largely only allowed in the section replacing the garage door. Any new windows added to the side of your habitation may require a planning application.
Key Works of a Garage Conversion
Making a garage into a liveable space isn't just a instance of moving your furniture into it. Hither's the basic process you tin can expect of jobs required during a garage conversion.
- Level, insulate and clammy-proof the flooring.
- Infill the garage door to create a solid wall if required
- Insulate the walls and the roof
- Plasterboard and plaster
- Decorate
Tin can I Brick Up My Garage Door?
The existing garage door is i element that needs addressing in your design. The most common road would be to infill this using walling that matches the building, or using blocks before using business firm cladding or firm rendering to unify the new wall with the existing structure.
Information technology may also be possible to retain a door, or use glazing in the infill to bring natural light into the space, also reducing the additional load on the existing foundations.
Foundations
Do Garage Conversions Need Foundations?
On of the key elements of converting a garage is blocking up the existing garage door opening (with an infill wall) — perhaps adding a new window or entry door in its identify.
In order to add an infill wall, you lot'll need to establish whether the garage foundations were continued beneath this opening and/or the concrete slab is adequate to back up the new wall. This may involve digging a modest trial pigsty in front of the concrete slab to check.
If the existing concrete slab is 200mm or over, this is more often than not adequate to extend straight up with new brickwork.
"If the existing slab is not adequate there are typically two options," says Stuart Letts. "Either a 1m basis will have to be dug and filled with concrete or a 140mm x 100mm concrete lintel can be added into the wall on both sides below ground level. The new infill wall can then exist built on pinnacle of that."
Information technology will also be of import to examination foundation force when extending over a garage, as this greatly increases the load exerting pressure on your foundations.
Speak with your designer, builder or a structural engineer in gild to ascertain the suitability of your foundations.
There are two primary routes for those who detect their existing garage foundations are inadequate.
Either a 1m footing wall will take to be dug and filled with physical, or a 140mm x 100mm concrete lintel tin be added into the wall, below ground level, on both sides. You lot can and so proceed to build a new infill wall on top.
Insulation
How Do You Insulate a Garage Conversion?
If you want your garage conversion be a comfy space to spend time in you will demand to ensure it is properly insulated. If the garage is integrated, it'south likely to have been congenital to the same standard as the remainder of the business firm in terms of its thermal functioning, but this is not always the case. The garage's structure will inevitably dictate the work required.
Adding external insulation is not usually recommended as, although it minimises the impact that extra insulation will accept on internal spaces, information technology can cause issues externally with wall thicknesses.
The simplest method is to use insulated plasterboard, stock-still to timber battens that are protected by a strip of clammy proof course (DPC) placed between batten and wall. Alternatively, insulation can be placed between battens, before a fireproof plasterboard is fixed to them.
Insulating a roof typically becomes a consideration in detached and fastened garages with no room above.
Otherwise:
- Inpitched roofs, go for 2 layers of 150mm glass fibre quilt, one between the joists, another over equally usual. A gap of 50mm should be left for ventilation.
- Flat roofs tend to demand one layer between of rigid PUR insulation lath and another below — the space in betwixt apartment roof joists yet can't be entirely filled. A 50mm air gap must exist left to a higher place for ventilation. The second layer underneath will driblet the ceiling tiptop a scrap. Typically 150mm deep flat roof joists will receive 100mm of PUR insulation between the joists and 50mm beneath them
Floor insulation is ever absent in a garage and including some in the conversion should be part of the project, whenever it's possible.
Garage floors are ofttimes lower than the firm floor and and so adding a damp proof membrane (DPM), insulation and a new screed, along with your last floor covering, is a good method for how to level a floor up to that of the residuum of your house.
You can use the existing concrete floor as a base, adding a solid or liquid DPM, before fitting a layer of insulation on height — building control volition advise on how much insulation will be required.
Finally, the new screed is poured, ready to have your new flooring covering. Be careful non to cover up any existing air bricks.
This is a practiced fourth dimension to retrieve nigh include underfloor heating within your garage conversion.
When working with very large differences in flooring levels, a new suspended timber flooring is a good idea. Aim to create a void beneath of at least 150mm betwixt the concrete and underside of the timber, placing insulation betwixt the joists, with new air vents to provide ventilation.
Ventilation
Exercise You Need Ventilation in a Garage Conversion?
"Home ventilation is vital for a garage conversion, otherwise you're only building a box that's going to sweat." says Mike Taylor from Taylor + Co Architects. Installing an openable window is an like shooting fish in a barrel way to purge ventilation. The opening should have an surface area of at least 1:20 of the floor surface area of the room it serves, whereas bathroom windows tin can be whatsoever openable size. Trickle vents should also be incorporated into the window framework to provide groundwork ventilation.
If your garage already has air bricks, these should not be covered up. Be mindful of Building Regulations regarding ventilation if converting a garage to include a bathroom, kitchen or utility room, as you'll probable need an extractor unit to ensure moist air can exist removed from the room. You'll notice all the information you need about ventilation in Building Regulations Role F.
Services
Garage Conversion Electricity Requirements
An electrician will be able to test the existing wiring and ascertain what work will exist required. If your conversion involves knocking down internal walls, they will need to exist carefully examined as well.
A lot of the time, a garage hosts electric meters and distribution boards, allowing for easy installation of electrics. New lights, sockets and electrical radiators could put additional strain on older consumer units, which may need to be upgraded. If you lot're installing wiring for a detached garage, it can be run through an underground aqueduct.
Information technology is possible to locate the garage on the current consumer unit. If it doesn't have its own miniature circuit billow (MCB), consider replacing the consumer unit or upgrading it.
If the garage is to be another habitable room in your house, its own MCB is probably enough. Consider adding at to the lowest degree one new twenty-amp circuit.
An boosted mains supply tin be installed, with the cost varying from £500 to £20,000. This will also crave the installation of a separate consumer unit.
How is Plumbing Added to a Garage Conversion?
A survey should be carried out to locate the main outflows for water (Equally well equally the waste matter pipe if you're installing a WC). Consider how far the garage is from the mains and waste material pipes of the principal firm. The further the distance, the more than digging pipes will add together to your project's cost.
Fire Regulations
What Are Garage Fire Door Regulations?
You must consider fire safety and the regs under Building Regulations Part B when it comes to your garage conversion projection.
"Attached garage conversions are unremarkably accessed by a hallway door, providing a safe means of escape to outside, just if you tin can only enter this new room from another (outer) room, it defines it as an inner room," explains building control officeholder Paul Hymers.
"Considering a fire in the outer room could prevent your escape, the inner room will need an alternative escape route. That could be a door or window and so the office is oftentimes performed by the one replacing the garage doors at the front. Escape windows accept minimum criteria. If you inner room is a kitchen, en suite, cloakroom WC or bathroom then information technology doesn't demand an alternative exit."
In partial conversions, where only function of the garage is being used as habitable infinite, the wall separating the two should be fire-rated to 30 minutes.
