A well-planned home extension has the potential to turn even the humblest of properties into a comfortable, stylish and light-filled home.

With the right design and execution, you can create a wonderful new zone that not only transforms the way you interact with your living environment, but also adds significant value.

Why extend your home?

There are lots of reasons why you need more space in your home.  Maybe the family is expanding, or someone is coming to live with you.  Perhaps you need more space to do the things you enjoy.  Whatever the reason, the simplest answer to gaining more space is not to move to a new house but to extend your property.  Extending your home and creating is more space is a lot cheaper and easier than moving to a new house altogether. Here’s a beginner’s guide to the world of extensions.

What should I consider before extending?

Insurance Make sure to notify your insurer of the work. Some may not provide cover during the works, but others will offer a dedicated extension insurance products.

Foundations – If your extension involves building or digging foundations within 3m of the boundary, party wall or party wall structure, or digging foundations within 6m of a boundary, the work will require you to comply with the Party Wall Act.

Deliveries – You will need to think about how deliveries and truck will reach the property and unload large items or material. You will also need to consider where builders will park and store their tools.

Boiler – Will your existing boiler will be able to cope with the new demands of the extension? Replacing the boiler completely would be an option or you may consider underfloor heating.

Other important factors to consider are:

  • Soil conditions on the site
  • Services
  • Surrounding trees
  • Any history of flooding
  • Rights of way
How much will it cost to build an extension?

Prices for extension projects vary significantly depending on factors such as the size, number of storeys, specification and which part of the country you’re building in. Extensions can be a tricky subject. It can be difficult to get a clear understanding of all the rules, regulations and costs. That’s why it’s a good idea to get a proper handle on extension costs before you dive in.

Payments

Builders will generally stage payments at each phase of the build. Try not to make any payments upfront apart from the initial deposit.

Your architectural designer or architect will charge fee’s according to the work involved.

How to Pay for Your Extension

Many people will borrow money to finance their extension. Ideally, we would all have savings to cover the costs of home improvements but unfortunately it doesn’t always work that way.

Your best options are:

Loan – Personal loans of up to around £25,000 are suited to smaller projects. The loan may be enough to cover the building work and if you are fitting kitchens or bathrooms in your extension you can often buy these on finance from larger stores. Just keep an eye on repayments as they can quickly add up when you borrow from several sources

Credit Card – If you need to borrow £1000’s rather than tens of thousands ` an interest-free credit card is a good choice. Shop around — the best deals offer up to 27 months of zero-rated spending

Reportage – If you are borrowing more than £25,000 you may need to reportage or take our a secured loan against your home.

Choosing a builder

When choosing your builder in Lincolnshire, you need to make sure they have the relevant experience, knowledge and availability to build your home extension. Choose someone you’d feel comfortable working with and talking to about concerns, they will be a big part of your life for a couple of weeks or months. The quotations they provide should be clear and easy to read, referencing the detailed approved building regulations drawings. Ask who will be doing the work, will they be subcontracting and who is responsible.

Breaking Down Different Types of Planning

This is a blog post aiming to help those who can’t decide on an extension type, are confused about the different types planning and what is allowed, looking at budgets and specification.

Planning permission is still a widely misunderstood concept, we sometimes feel like we are in the dark.  Laws can and will change which in turn can take advantage of homeowners or members of the public looking to add an extension, do some remodelling or create a new dwelling within the boundaries of our land.

The different types of planning are as follows:

  • Householder Planning Application
  • Full Planning Application
  • Outline planning consent
  • Reserved Matters
  • Listed building consent
  • Advertisement consent
  • Lawful Development Certificate (LDC)
  • Prior notification
Typical Types of Extension

The most frequent one we see is for an existing property in need of extra space, wanting to either develop to the rear (a single storey or even double storey rear extension), or to the side.

A frequent form of extension which allows the homeowners to add lots of vital ground floor space is a single storey ‘wraparound’ extension, which combines the rear extension with the side extension to create a large ground floor open space.

The double storey rear or side can add space upstairs also, with the addition to an extra ‘wing’ at the side of the house, generally located at the top of stairs an extra bedroom or 2 can be achieved through careful planning and layout.

Loft conversions which can include dormer windows (flat roof and gabled), usually to the rear as planning prefers this, and can create a 3rd floor in the dwelling to add a large master bedroom with en-suite, along with extra storage space in the eaves where headroom is lower. This can be overcome with adding a dormer window, to the rear of the property, to allow extra headroom, light and space, as well as lots of value on to the property, it is a good idea that this is carefully planned. Velux windows can be added to add light and don’t require planning permission and are therefore classed as permitted development.

Restrictions

There are certain restrictions on some developments, if the house lies in a conservation area, is a world heritage site, a site of specific interest or a listed building (will need listed building consent), and at all time boundaries need to be respected.  Any development more than 3m in length, will need to be 3m from the boundary also (known as the 45-degree rule), whereby rights of light for the neighbour will be respected, as well as privacy issues, therefore most windows/opening tend to be on the rear rather than facing the side.

Dormers tend to be on the rear, any development to the front facing the road must be subservient to the main house (can be slightly set back – and depends on the neighbours), and height of single storey can be maximum 4m of original eaves height. Two-storey extensions no closer than seven metres to rear boundary.

“No more than half the area of land around the “original house”* would be covered by additions or other buildings”. However, this can be important as if houses were built with detached garages, outbuildings etc in a good plot of land, this can be used as original area, therefore we can gain 30% (argued as permitted development potential) plus another 30% through either permitted development and then the 50% as planning permission. If the house was already extended after 1948 then this would be part of the 30% area allowed under permitted development.

Permitted Development

According to the Planning Portal “The increased size limits for single-storey rear extensions that were previously time limited and due to expire on 30 May 2019 have now been made permanent by government.”

Class A – Extensions (enlargement, improvement or alteration)

This means for both planning and permitted development, the size of extensions has been increased (doubled), 6m for semi detached and terraces houses, 8m for detached. Therefore, a single storey space can be added to the ground floor, offering a great open plan space with glazed openings to the garden (if rear garden space permits), with a maximum 3m second storey addition to form an extra bedroom or 2.

Class B – Additions to the roof

This allows for rear dormers and hip-to-gable extensions if the additional volume created does not exceed 50m3 (40m3 for semis and terraced homes).

Class C – Other alterations to the roof

Class D – Porches

Class E – Buildings etc. (outbuildings)

This allows for an outbuilding to be erected within a residential curtilage if it is sited behind the principal (often the front) elevation, does not cover more than 50% of the curtilage and is not more than 3m in height (4m for a dual-pitched roof; 2.5m where within 2m of a boundary).

If the 6m or 8m single storey rear extension is to be agreed, a certificate of lawful development via prior notification (to the authority and neighbours) is submitted, if there are no objections by either then the certificate can be awarded, and work can commence.

Agricultural Land/Change of Use

Another large potential is that agricultural buildings may be converted to residential (up to 450m²), if the building is structurally capable of being converted without requiring engineering work and providing access can be achieved. Up to five dwellings may be created up to a maximum floorspace of 465m², of which three may be ‘large’ (>100m²), and 2 smaller i.e. 80m². This change of use is subject to prior approval being sought in respect of transport, access, noise assessments, ecology reports, flood risk, may be required by the authority depending on sites and plans for that given site.

Costs

Typical costs for a single storey rear extension are around £1,500pm2, (ranging from £1,000-£2000), or greater if a high spec kitchen/furnishing are desired. A typical 3x5m extension would cost around £20,000-£30,000. If you want a double storey it would rise to around £50k, around the same as a single storey wraparound extension. Larger width rear extensions, large wraparounds, or double storey side extensions with rear single storey rear can be from £60, 80, 100k +, depending on spec, bifold doors, kitchen layout/cost, what ground works are needed as foundations/structure may need to be improved/built to take the weight of the new extension.

Architects fees can be anywhere from 2 or 3, 5-10% of the build cost depending on level of service desired, to get through design options, planning, building regulations, working drawings (inc electrical/M&E layouts) and project management. A typical £40-60k extension may cost £2-4k in fees depending on option chosen.
