Whether you want to extend your home to create a study, a dining area or simply a place to relax, a conservatory could be the answer. It's never too early to plan ahead and autumn is a good time to undertake construction work. Noel Rowe, managing director of Roweco Building Contractors, which has over a decade of experience in the property maintenance, refurbishment and construction, answers customers' most frequently asked questions.

What are the advantages of a conservatory?
Building a conservatory is the cheapest way of providing extra internal space, as well as adding value to your property, as much as 5%, as long as it blends in with the style of the property. There are various Victorian or Edwardian styles available to suit your taste.

What are the factors to consider?
Ensure that the conservatory is built to meet your needs. Will it be a sun-room or will it be in use throughout the year? How will you use it - a plant room, a playroom or an extension of your living room? This, in itself, will be determined by the specification and cost. Then, decide how big you want it. Remember that the bigger the conservatory the more you reduce the size of your garden.

What types of materials are best to use?
Wood works best for more traditional designs but the most popular choice of material is PVCu which is a good insulator and cost-effective. It comes in white but is also available in mahogany and oak. Internally reinforced with steel or aluminium, it has the advantage of withstanding discolouration. Aluminium is similar to PVCu but it is more expensive and not such a good insulator.

Will it be too hot in summer or too cold in winter?
South-facing conservatories, with a lot of sun, will need a ventilation system. You should also take into account that glass roofs intensify heat. Blinds are the best way of counteracting this. North-facing constructions may need heating. I would recommend underfloor heating.

Is planning permission required?
You do not need planning permission to build a conservatory as long as you meet certain criteria, such as the floor area not exceeding 30 sq metres; it is on ground level and that the construction is mostly glazed with no more than 25% of the wall made of brickwork. Contact your local council planning department if you are in any doubt. Building Control will advise on standards, such as the health and safety of users.
