Garage conversions

Garage conversions in Hull & East Yorkshire.

If your garage is used for storage rather than a car, converting it is usually the most cost-effective way to add a genuine extra room without extending your home's footprint.

Integral or detached

Two types of garage conversion.

Integral garage conversions

Where the garage is built into the main structure of the house, an integral conversion usually connects straight into the existing floor plan, making it a natural fit for extending a kitchen, adding a bedroom, or creating a home office off the hallway.

Detached garage conversions

A separate garage building gives more flexibility as standalone space — a gym, playroom, home office or annexe — but needs its own services run out to it, similar to a garden room.

Popular conversions

What people convert their garage into.

We also convert garages into additional living rooms or snugs where an integral garage sits next to the main reception rooms.

Design & build

What goes into a proper garage conversion.

Insulation & damp proofing. Garages are rarely built to the same insulation standard as the rest of the house, and older garage floors often sit below the damp-proof course of the main building. Both need addressing properly before the room is usable, rather than papering over them.

Flooring. The existing garage floor is usually lower than the house floor level, so raising and insulating it is a standard part of most conversions, along with removing any historic oil or fuel staining.

Windows & doors. The garage door opening is typically bricked up or replaced with a window and matching brickwork, and additional windows may be added depending on the room's new use and available natural light.

Heating & electrics. First and second fix electrics and heating are extended from the main house, with sockets, lighting and data points planned around the room's intended use.

Plumbing. Where a conversion includes an en-suite, kitchenette or utility space, we run water and drainage from the nearest existing point, which is more straightforward on an integral garage than a detached one.

Planning & regulations

Planning permission and building regulations for garage conversions.

Converting an integral or attached garage into living space usually doesn't need planning permission, since it's an internal change of use within the existing footprint that doesn't normally alter the external appearance significantly — though this can differ if you're also changing the garage door opening to a full window or altering the roofline. Building regulations approval is required regardless, covering structural work, insulation, damp-proofing, fire safety (particularly where there's a room above the garage), ventilation and electrics. Detached garage conversions follow similar building regulations requirements, and may be more likely to need planning permission if the intended use, height or appearance is changing significantly.

This is general guidance rather than an assessment of your specific garage. We'll confirm what applies during the consultation and manage any application to Hull City Council or East Riding of Yorkshire Council.

Cost

Typical garage conversion cost considerations.

Cost depends on the garage's condition, whether plumbing is needed, and the finish specified, so treat the figures below as general UK guidance rather than a quote — the only way to get an accurate number is a site visit.

Basic conversion

Roughly £6,000–£12,000 for insulation, flooring, plastering and electrics only — a typical spec for a simple storage-to-office or playroom conversion.

Mid-spec conversion

Roughly £12,000–£20,000 for a conversion including heating, new windows and a higher-quality finish, such as a bedroom or living room.

Higher-spec conversion

Roughly £20,000–£35,000+ where plumbing for an en-suite or kitchenette is included, along with bespoke finishes.

Process

How we run a garage conversion.

  1. Survey & design

    We assess the existing garage, check for damp and structural issues, and design the new room around how you'll use it.

  2. Regulations check

    We confirm the building regulations and any planning requirements for your specific conversion.

  3. Construction

    Insulation, damp-proofing, flooring, windows, electrics and (where needed) plumbing, coordinated under one schedule.

  4. Finishing & handover

    Plastering, decorating and a final clean, with a walk-through of the finished room.

Timescale

How long does a garage conversion take?

A straightforward integral garage conversion typically takes around 3–5 weeks on site once damp-proofing, insulation and any structural work are accounted for. Conversions including plumbing for an en-suite or kitchenette, or detached garages needing new services run out to them, usually take longer. We'll confirm a realistic programme once the survey is complete.

Frequently asked questions

Garage conversion FAQs.

Do I need planning permission for a garage conversion?

Usually not for an integral or attached garage, since it's typically an internal change of use within the existing footprint. This can differ if you're changing the garage door opening to a full window or altering the roofline, or converting a detached garage in a way that changes its appearance significantly.

Do garage conversions need building regulations approval?

Yes, building regulations apply regardless of planning permission, covering structural work, insulation, damp-proofing, fire safety, ventilation and electrics.

Is my garage floor a problem for conversion?

Often the floor level and damp-proofing need addressing as standard, since garage floors are usually lower than the house floor and not always built above the damp-proof course. We assess this during the survey.

Can you add an en-suite to a garage conversion?

Yes, where plumbing can be run from a nearby existing point, which is usually simpler on an integral garage than a detached one.

How long does a garage conversion take?

A straightforward integral conversion typically takes around 3-5 weeks on site, with more complex conversions including plumbing taking longer.
