Garage conversions and annexes we deliver in Gateshead
Convert Garages converts attached and integral garages into annexes with a bedroom, shower room and kitchenette, ground-floor bedrooms, home offices and gyms. A conversion can be full, or partial so that the front of the garage stays as a store. In suburbs such as Low Fell, Whickham and Ryton the garage is rarely level with the house, so on Gateshead's sloping plots the delivery starts with the ground.
How the work is delivered
We begin by assessing the garage: floor levels against the house, damp, the roof and the way rainwater falls across the drive. The layout is then planned around the person who will use the room, with mobility, privacy and the route to a bathroom in mind. Planning and building regulations requirements are established before work starts, and we agree who is responsible for drawings, applications and inspections. You then receive a specification and a quotation that shows exactly what is included. Construction follows an agreed sequence through to handover.
What you can expect
You get a clear quote, with responsibilities and the order of work agreed up front. Any change is discussed with you before it is made. At handover the finished room is checked with you, along with the building control sign-off.
Which Gateshead households is this service for?
Households who want more room without moving. Some are caring for an older relative and need a bedroom with a shower room nearby. Others have teenagers or adult children at home and want to give them some independence. A smaller number want a quiet office or a home gym. The common thread is a semi or detached house with a garage that has become a store, on a plot that rarely sits flat.
Annexes and ground-floor rooms we design for relatives
An annexe gives the person their own space while they still share the main household, with the kitchenette included only where it suits how they will live.
When a bedroom conversion is enough
If the relative will eat with the family and mainly needs a room without stairs, a bedroom near an existing bathroom may do the job at a lower cost. We will say so at the assessment stage rather than design more than you need. Our page on extra bedrooms and living space covers that simpler route.
Agreeing how the annexe will be lived in
A room used by members of the same household is treated differently from a separate home with its own front door, kitchen and bills, and a self-contained dwelling normally needs planning permission. Convert Garages records how the space will be used before the design is fixed, so the approvals match the reality. That also helps when you come to sell.
Is a garage below the house still worth converting?
Usually, yes, but the level change has to be designed in from the start.

Raising the floor or stepping down
Where the garage floor sits below the house floor, there are two routes. Raising it to meet the house makes the room feel part of the home and removes a trip at the doorway, and it gives depth for insulation. It works best where there is generous headroom. Where the ceiling is low, or the roof slopes down towards the back, keeping a step or two and using the full height may give the better room. We set out both options with the layout so you can see the trade-off.
Thresholds for someone less steady on their feet
If the room is for a person with limited mobility, we look hard at steps before adding any. In a long garage a gentle internal ramp is sometimes possible. Where an external door replaces the old garage door, the threshold has to keep rain out without leaving a high lip to step over.
Walls against the bank and water on the drive
On Gateshead's steeper streets some garages are partly cut into the hillside, so one wall holds back soil and can let moisture through. Before that wall becomes the side of a bedroom, it needs a proper waterproofing system, such as a cavity drain membrane or tanking, not just insulation and plasterboard. Ventilation gets the same attention, because a room with one wall against the ground and a single window can suffer from condensation.
Water also runs downhill. A garage at the foot of a sloping drive can collect surface water in heavy rain, so we check where it goes and, where needed, specify a channel drain in front of the new wall. A shower room that sits below the main drain may need a pumped system. Knowing that at the start keeps it in the quotation rather than appearing halfway through, and the garage conversion cost guide explains what moves the price on a sloping plot.
Smaller garages behind Gateshead terraces
Older terraced streets in Gateshead often have garages, where they exist, at the back of the yard or off a rear lane. These are usually small and separate from the house. They can make a good workshop, store or office, and our home office conversions page shows what can fit. A room for a relative is harder to justify in one, as it sits away from the kitchen and bathroom and may need a lot of upgrading.
The planning and building control position
Gateshead Council is the local planning authority. A conversion that stays inside the existing garage, with no external enlargement, does not usually need planning permission. That can change if a condition on the original permission keeps the garage for parking, if permitted development rights have been removed, or if the house is listed or in one of Gateshead's conservation areas. Convert Garages checks the planning history and any designation for your address before construction is booked.
Building regulations approval is normally needed to turn a garage into habitable space. It can be handled by the council's building control service or by a registered building control approver, and either will look at insulation, ventilation, fire safety and escape. If that all sounds manageable, request a quote and we will start with the garage itself.
Photos and measurements for your quote
It helps to photograph the things a slope affects:
- the garage from the road or drive, showing the fall of the ground
- the floor inside compared with the step into the house
- any wall against the bank, and signs of damp
- where rainwater runs on the drive
- your postcode, rough internal measurements and who the room is for
