Building your Extension

Building your Extension

Building an extension to a house is an increasingly popular choice for homeowners seeking to maximize the potential from their property space. With fees and stamp duty to consider as well as the upheaval entailed with buying a new house and continually increasing property prices, an extension can be seen as a more economical option.
The type and scale of house extension varies greatly according to the homeowner’s requirements, budget and the feasibility of the site.

Porch 

 

This is a single-storey attachment to the front of a house. Due to their relatively small size they may not require planning permission (although they may in a conservation area or for a listed building). Building regulations approval may be required if the porch is not separated from the house by an internal door and is heated, or if there are structural, accessibility or drainage implications.

Conservatory 

 

These are simple single-storey structures, usually made of glazing and a UPVC frame, although they can also be timber or aluminium. They may have a low-level brick wall around their perimeter upon which the framework site. The type and size of the conservatory will determine whether planning permission, permitted development or building regulations approval is required or not.

Single-Storey Extension 

 

A single-storey extension is built adjoining the existing house. The method of connection requires careful consideration, in particular, openings between the extension and the existing building, junctions with the roof structure, the positions of flues and drains, and so on. Planning permission may not be required in all instances, but permitted development or building regulations approval will be.

Two-Storey/Multi-Storey Extension 

 

The same considerations will be relevant as for a single-storey extension, although the junctions and structure are likely to be more complicated and planning permission will be required.

Basement

 

In areas such as London, due to the demand for housing, the price of land and the cost of moving, basements are being constructed or converted for living space. This is causing concern in some areas where very large, multi-storey basements are begin constructed, which can cause significant disruption to neighbours over a long period. As a result some planning restrictions are being introduced. See Basements in buildings for more information.

The planning situation will depend on the exact nature of the proposed development and so it is advisable to contact the Local Planning Authority for pre-application advice. Building regulations are applicable to the construction of new basements, and will cover areas including ventilation, drainage, ceiling heights, damp proofing, electrical wiring, water supplies, means of escape and so on.

Loft Conversion

 

Loft conversions can increase the value of a home by up to 20%, and can add up to 30% more living space to a house. In many instances, loft conversions can be completed as Permitted Developments, which do not require planning permission. However, if the plans fall outside of these limitations then planning permission will be required. Planning permission may also be necessary if the house is in a conservation area or a listed building. Building regulations approval is required to convert a loft into a liveable space.
