Garage Conversion Building Plans

We use the latest Cad software to produce the building plans for your garage conversion. We offer a cost effective design solution for garage conversion design.

One day design process available!

(See our F.A.Q.)

A garage conversion is one of the most cost effective ways of extending your home, Generally cheaper than a similar sized extension. Most garage conversions are exempt from Planning Permission, but will require a Building Regulation approval.

A recent study by the Halifax Building Society stated "The cost of converting a standard garage is around £8,000, with a value gain on the property of around £10,000 - £15,000"

We can provide your plans for a garage conversion at a very competitive price and we also guarantee a Building Regulations Approval.


Testimonials and Design Samples

"Thanks for your excellent plans. We needed some input from an architect for our garage conversion and kitchen extension plans. Your plans are extremely detailed and we were able to get 3 reasonable quotes from local builders. We had been quoted more by a builder before we had the plans drawn up and as you said, the builders quotes came down in price once we had a good set of plans. Thanks"

Why are your fees less than I have been quoted by a local architect?

We use the latest technology in measuring and designing your garage conversion. We only deal with small projects and extensions and are able to give our full effort in looking after our customers. Architects and surveyors may well have large projects such as new housing estates or buildings to design so your project may be a small part of their workload.

Will I require planning permission for my garage conversion?

Over 70% of garage conversions will not require planning permission. This type of work is classed as internal and does not involve enlarging the building. The 30% that do require planning permission are in conservation areas, listed buildings or the building has restrictive covenants.

Permitted development rights have often been removed on new housing estates up to 10 years old. If you live in a new estate it might be worth a phone call to the local planning department to see if your permitted development rights have been removed.

Will I require building regulations approval for my garage conversion?

Building regulations approval will be required on all garage conversions. We will produce the plans for you and submit them to your local authority for a full building regulation approval.

We would advise you to be careful with building notice applications. This is where a builder constructs your garage conversion without a set of approved plans. If you don't like your garage conversion after its been built or the building Inspector finds a problem, it can prove very expensive to change.

Do you charge any more for a double garage conversion?

No. It takes us the same amount of time to design a single or double garage conversion, so our design fees are the same.

What happens if the garage conversion building regulations application gets rejected?

We guarantee a building regulations approval or we will give you a full refund for the plans.

Do you fill out the local authority application forms and submit the application to the local authority?

All forms and designs will be submitted by us to your local authority planning department.

Do you charge for amendments to the plans if the local authority want our garage conversion changing?

We don't charge when the local authority want to change your plans. Changes are included in our design fee.

Do we chose a solid floor or suspended floor?

We would assess on site the feasibility of both flooring systems.

Suspended floors are often installed where the internal floor level of the property is quite high and we want to match over the floor heights.

We would recommend a standard solid floor if you have a standard 150mm finished floor to outside ground level.

How many sets of plans will I receive?

We provide you with 4 sets of A1 paper plans and a PDF digital set for your own records.

We submit the planning application on the planning portal as this saves several days over postal applications.

If you have any questions you would like answering about our garage conversion design services please contact us.

"Thanks for the plans. The approval came through the week after you submitted the application to the council. We got 3 quotes from builders and are very happy with the results. We now have an extra play room and a small home office. The house feels more spacious with the kids able to use their room and I finally have somewhere to work from home".
