Double storey extensions

Double storey extensions are an incredible way to truly maximise your house value and make more space at the same time.

A double storey house extension in Scarborough adds living space to both the ground and first floor of your house. As well as all of the benefits of a single ground floor extension, extending on the first floor can then add bedrooms, bathrooms, en-suites, office space or anything else you’d like to enjoy in your home. A good architect or architectural designer will be able to give you the right advice and options.

Extending double doesn’t mean double the price either, because the additional floor will not require additional foundations and roof as they’re part of a single-storey extension anyway. If you want more space top and bottom this could be the best option for you.

Whatever your double-storey extension needs to achieve, the CK team can help. We’re experts in bringing double-storey extensions to life, designing every step of the journey and helping you find your perfect match. Contact the team today to discuss your project with our specialists.

Designing a double storey extension

All of the staff at CK Architectural Scarborough are trained and experienced in getting the best out of the available shape and sizes extensions have to offer. With two stories, the planning limitations have to be considered as the size and scale means it has to be designed to fit with its environment, as well as of course being perfect for what you need.

Layout and access upstairs are a key issue and you need to know where you can have windows for bedrooms. Landings are not always in the best place to serve additional rooms so careful design on accessing new rooms without ruining others with corridors are required.

Before we design a full assessment of the site is required, knowing where the drains/boundaries are, determining how it looks from the street and the risk of blocking your neighbour’s light becomes an issue. We always consider the regulations as first floors need more thought about means of escape.

Planning permission guide

Planning permission your home extension design

Double storey extension generally need planning permission as the permitted development rights only permit small sizes. There are a lot of things to consider before submitting a planning application. How it impacts the street scene, does it enhance character, does it have negative effect on the neighbours, does it effect light/privacy/amenity. These are the things the planning officer will be checking whilst making their decision.

Our design consultants will give you the best advice on how to achieve your requirements with the best chance of securing planning approval. We will prepare and submit he application on your behalf, then act as your agent talking directly with the council throughout the application.

Highly recommend CK Architectural. Chris and his team did a great job gaining planning permission for a new build and renovation of an existing property. We hit some dead ends with the planning officer but Chris found different ways of getting around the problems without going over budget.

For someone far removed from the building / planning industries the thought of where to start when thinking of a big extension project to my house (two story to the side and wrap around of semi-detached 3 bed) was a little daunting at first. Luckily, after obtaining a competitive quote, I enlisted the services of CK Architectural and have been very impressed with not only the service received but the ease at which they have made the whole process. After listening to my thoughts and the reasons for needing the extension work doing, the architect came up with a great design that encompassed everything that was needed. Even when I changed my mind over a couple of aspects, Donna, Chris and the team were quick to administer any alterations. Every visit to the house for measurements / planning etc has happened without a hitch with all members of the team we've encountered being punctual and professional at all times. The best thing has been by far the ease at which CK have made of getting all council and local authority sign off for the project. All I have needed to do is pay the fees at the required time, no stress involved and all went through seamlessly. I'm now at the stage where I have the drawings to hand and have submitted them to builders to obtain quotes. Importantly, the feedback so far from the builders indicates the project to be within the budget specifications I explained to CK during the first consultation. Very happy customer 🙂 Carl.

Building regulations for double storey extensions

Before building, you will need detailed plans to submit to your local authority or private building control authority. All extensions need a building certificate from building control, and this is gained by full plans approved and site inspections. Given the additional complexity of meeting the building regulations for a two-storey extension, it is essential that you get the plans approved prior to commencing.

Our plans will include all the necessary detail such as structure, the passage of sound, disability access, drainage, resistance to moisture, collision, impact, heat loss, ventilation, light, emergency escape, and much more. These drawings are useful in tying up the quotation from your appointed builder and they will be inspected against what has been approved.

Notes for building your home extension

The extension plans that you receive from CK Architectural are almost always enough for an experienced builder to begin working with, but although we will do our best to warn or design against potential building issues, when a build takes place, sometimes issues do arise from aspects not undertaken by ourselves. It is worth remembering we cannot see underlying issues behind walls or underground.  You should make allowances for this and ensure that the builder prices for issues if they arise.

Be aware to look out for poor ground and drainage and make sure the builder undertakes a CAT scan before excavation in order to make sure that any issues don’t occur through the build. This is one of many reasons people tend to stay with the CK team for the project management service, however, in any case, it’s always best to be aware.
