Will a garage conversion add value to a house?

A garage conversion can add up to 10% to the value of your house – allowing you to enjoy the benefit of your new space in the present, and also the higher asking price in the future.


Is planning permission required for a garage conversion?

Planning permission is not required for garage conversions if you are not altering the structure of the building itself. However, there are exceptions – if you live in a Conservation Area or Listed Building, or if you home has specific requirements for your garage to not be altered, you may wish to double check if conversion is feasible for you.

Your new build will change the use of the space and have to comply with building regulations, including a building regulations sign-off – this is to adhere with legal standards on insulation, ventilation, fireproofing, and other key features. More information can be found on government websites.


Should I keep the garage door?

Converting a garage doesn’t mean you need to get rid of the door! Keeping your garage door when you convert preserves the multi-purpose usability of that space for future buyers. Not only this, but garage doors can become a unique feature of the space when decorated in the right way – you may wish to replace your current garage door and choose a homey option that seamlessly complements your conversion but keeps its usability as a garage door for future sale. Here at Doormatic, we can advise you further on your wide range of choices.


Can you do a garage conversion yourself?

If you want to direct your conversion from start to finish – or if you are on a budget – this job can be the perfect DIY project. Make sure you secure conversion insurance before you begin – ordinary home insurance may not cover conversions, so don’t get caught out!

If, however, you are keen to ensure every detail is handled by a professional, there are many specialist designers and contractors who can help you create an extraordinary space that works for your needs. Doormatic can advise on the perfect door to suit your space.
