WHAT YOU NEED TO KNOW ABOUT BUILDINGS AND TRUST AND HOUSE EXTENSION HAMPSHIRE

Firstly, house extensions add value to your home and provide valuable living space or that downstairs bathroom. Furthermore, you could add another bedroom, a garage and another bedroom above it. Finally, the choice would be entirely yours as to what to do with the extra space.

With this in mind, speak to your estate agent for advice. The estate agent will tell you how much the planned extension will add to the value of your property. Chiefly, ensure the value of the property matches and surpasses the cost of the investment!

HOUSE EXTENSION

At Buildings and Trust and House Extension Hampshire, our professional builders possess all the necessary building expertise and experience to deal with any house extension. House Extension Hampshire can build your dream house extension effectively and efficiently.

Permitted Development Rights (PDR) and House Extensions

Notably, Permitted Development Rights allow homeowners the right to build certain types of extensions without applying for full planning permission. However, Permitted Development Rights only apply to homeowners live who do not live in a listed buildingConservation Area, or a Designated Area:

 

In light of this, you can check online with the Planning Portal to read more about your Permitted Development Rights and Designated Areas. Alternatively, you can check with your Local Planning Authority for them and whether or not PDR are affected by them.

HOUSE EXTENSION

Buildings and Trust and House Extension Hampshire offer quality and reliable building services.  Our friendly house extension team always try to keep house extension solutions well within your budget.

  • Side extensions should not project outwards from the original home and should be 500mm back.
  • The extension must not take up more than half the space of the garden.
  • The ridge height of the extension must not be higher than the ridge height of the original house.
  • A two-storey wing must not be nearer than 7m to the rear boundary fence.
  • A side extension must be single-storey and not exceed 4m in height.
  • The extension must not exceed half the width of the original house.

HOUSE EXTENSION HAMPSHIRE PROCESS

Permitted Development Rights, Prior Approval, Lawful Development Certificate, Building Notice

You must realise that you must obtain prior approval and a Lawful Development Certificate from the Local Planning Authority even if you have Permitted Development Rights. Furthermore, the Lawful Development Certificate is proof from the Local Planning Authority that the extension is lawful under Permitted Development Rights. Finally, the cost of a Lawful Development Certificate is £206.

In addition to a Lawful Development Certificate, you will need a Building Notice. The Building Notice is a statement informing the Local Planning Authority of the extension you wish to build. At the same time, the Building Notice ensures that all building work complies with proper Building Regulations.

Extension Regulations and Restrictions with Full Planning Permission

Above all, you must apply for full planning permission through the Local Planning Authority or the LPA if you don’t have Permitted Development Rights for your extension. Despite this, recent planning application changes mean the LPA will speed up the process for a two-storey house extension.

However, you will need a prior approval notice to fast-track your application. Correspondingly, it would be best if you did not start any development until you get a preliminary approval notice from the LPA.

Specifically, you cannot erect a double-storey extension if you live in a Designated Area. Namely, all extensions in Designated Areas must be single-storey only.

Read more about the planning application process in our Loft Conversion Definitive Guide.

Building Regulations

Most importantly, Building Regulations are legislative requirements for builders and homeowners to comply with building control measures. Moreover, the Building Regulations come in the form of Approved Documents. Finally, there are different Approved Documents:

Part A: Structure

Specifically, the extension must be structurally sound and can resist and withstand external forces such as wind and rain.

Part B: Fire safety

Most importantly, extensions must contain materials that are fire resistant and can resist the spread of fire. Furthermore, this is especially so if the extension is going to be a kitchen. In addition, the safety of both the building and the occupants is of paramount importance. With this in mind, the extension must also possess adequate fire detection equipment.

HOUSE EXTENSION

Buildings and Trust and House Extension Hampshire pride itself on offering high-performance house extension solutions.

Part C: Site preparation and resistance to contaminants and moisture

The first thing to remember is water penetration into a building can cause untold damage. In the first place, the sight of black mould spreading around the wall or ceiling is a nightmare! As a result, structural damage can happen when water penetrates the extension and begins to degrade the materials and structure.

In conclusion, all extensions should withstand the passage of both moisture and other contaminants.

Part E: Resistance to the passage of sound

Firstly, adequate sound insulation is essential when building an extension. Consequently, builders should only use suitable materials with the necessary sound insulation properties. Finally, this will help to keep out sound from outside and give a degree of privacy inside the extension.

BUILDING REGULATIONS

Building Regulations

Part F: Ventilation

Most importantly, house extension builders should install a sufficient and functioning level of ventilation in the extension. As a result, ventilation helps to reduce the build-up of moisture.

Part G: Sanitation, hot water safety and water efficiency

Most importantly, all sanitation, hot water, and water efficiency should meet the required building standards. Moreover, Part G must be carefully considered at the planning stage if you plan to install a bathroom in the extension.

Part H: Drainage and waste disposal

For health, proper and adequate drainage should be available to dispose of wastewater. In light of this, all pipework, sewage, and other water discharges will have to be sufficient.

Part M: Access to and use of buildings

Most importantly, you must consider access to and the use of your extension not only for yourself but for the next occupants.

Furthermore, building Regulations require you to provide the necessary access for both able and disabled people. In addition, circulation around and in and out of the extension will also have to cater for all needs.

Part N: Glazing – Safety concerning impact, opening and cleaning

Most importantly, serious injuries occur when someone impacts and breaks a window. Part N: As can be seen, glazing ensures that windows possess adequate protection against impact. Also, windows are built to a stipulated height to avoid impact.

Part P: Electrical safety

All electrical wiring, consumer boards, sockets and plugs must be safe to protect occupants against shocks and burns. Consequently, a qualified electrician must access the existing consumer unit.

ARE THERE ANY FURTHER RESTRICTIONS FOR HOUSE EXTENSIONS?

Party Wall Act

The Party Wall Act 1996 helps prevent unnecessary neighbourly disputes arising from the proposed extension. The Party Wall Act 1996 states that if a property requires:

Excavating foundations within 3m of adjoining properties, or party wall, or party wall boundary

Excavating foundations within 6m of a boundary line.

You will need to get your neighbour’s permission to do so. Under the Party Wall Act 1996, you must notify the neighbours of the intended extension. In addition, trial holes may be necessary to determine the depth of existing foundations and footings.

Services/Utilities

It is essential to check that the current service and utility requirements are adequate before building work can begin. Adding a new ring main or installing extra radiators will place additional demand on electrics and the boiler.

It is best to speak to a tradesperson about service requirements for the existing property and the new extension.

The builders will need to install all utilities and services before the builders can build the extension.

HOUSE EXTENSION

Buildings and Trust and House Extension Hampshire specialists will present you with various options and house extension solutions to match your budget.

Access

Planning and sorting out how vehicles can access your property to off-load building materials is essential. The planning can also involve road and pavement access. Each property will have different access requirements.

Visit your Local Planning Authority is necessary to determine what access requirements to prepare for and what to avoid.

In addition to planning access, you will need to check that you are not impacting any public right of way.

In addition to vehicular access, you must comply with Part M: Access to and use of buildings.

WHAT OTHER RESTRICTIONS MUST I CONSIDER?

Rainwater Run-off and Risk of Flooding

The new extension will likely increase rainwater run-off. Carefully manage the run-off to prevent the rainwater from making its way onto roads and pavements.

In addition, you will also need to check whether the extension is in an area prone to a history of flooding.

Soil Conditions

The builders will have to know the soil conditions under the extension. The soil conditions must be sound enough to support the new extension structurally. If the ground is loose, builders will install suitable foundations.

Please pay attention to surrounding trees and how the new extension could impact them. More importantly, make sure you determine whether any trees possess a Tree Preservation Order or TPO, which means the tree is under protection.

HOUSE EXTENSION

Buildings and Trust and House Extension Hampshire team of specialist builders work to the highest building standards.

Extension Size

The size of your extension will depend on its purpose. A simple lean-to extension generally requires only a few square metres. However, a garage extension with an upper bathroom will need considerably more square metres.

Kinds of Home Extension Construction

As with the extension size, the manner and look of your new extension will depend on what you want, your budget, and any planning or physical constraints.

Materials

Materials used on a new extension will often complement the existing materials on the main property, mainly if the extension is a side extension and is visible from the street.

When deciding the materials to use on the new extension, choose sustainable materials with a low carbon footprint.

WHAT IS THE COST?

As can be seen from the previous section, there are a host of both regulation and technical regulation factors to consider when determining a price for that new extension:

  • Permitted Development Rights (PDR)
  • Building Control
  • Building Regulations
  • Party Wall Act
  • Extension Size
  • Manner of Home Extension Construction
  • Services
  • Access
  • Utilities

HOUSE EXTENSION

Buildings and Trust and House Extension Hampshire trustworthy team of reliable builders will sort out the solutions.

Most importantly, prices will vary considerably for a new home extension. In the South, and in particular, around the London geographical area, the cost of a new extension will always be higher than in the northern Midland parts of the UK.

Furthermore, material costs can fluctuate and so can tradespersons” daily rates vary. Therefore, carefully consider all this when planning a new home extension. Ensure you have assessed all these variations and how they will impact your budget.

Another essential rule is constantly assessing and working with the higher price factor, which will help soften unexpected problems.

A home extension can cost anywhere from £1000 to £2000 per m2.

When deciding whether to have a single or a double-storey extension, one crucial point is that the double-storey won’t necessarily be a substantial extra cost! Ensure you pay attention to all the groundworks, services, access, utilities, and Building Regulations. Nevertheless, ensure you don’t compromise and end up with something shoddy and cheap.

WHAT KINDS OF WAYS CAN MAKE A HOUSE EXTENSION CHEAPER?

Go for a simple design. Avoid flashy and intricate designs that will increase your home extension’s cost. Keep the roof simple, and try to use cheaper materials wherever possible. Rendered blockwork is cheaper than fancy brickwork but can also look aesthetic.

Another way to lessen the financial impact of a home extension is to think long-term. You could split the home extension project into different stages. You could start by simply having the structure built.

HOUSE EXTENSION

Buildings and Trust and House Extension Hampshire provide cost-effective and affordable house extension quotes.

Later, when the money pot is healthy again, you could have all the fixtures and fittings installed. Finally, you could have the home extension furnished. And one last point: if you feel confident in the art of DIY, that will help save money on the home extension.

Most people, however, don’t want the hassle and the stress of undertaking any work themselves, which is understandable. Leaving the work to the professionals will mean all you have to do is to sit back and watch the building of the home extension. Admittedly, the cost will still be there, but the stress won’t.
