Is this the job you need?

The house is right. The space is wrong.

Moving costs stamp duty, fees and a new school run. An extension keeps the street, the neighbours and the garden, and adds the room you're short of.

Extension builders in Medway

Extending a Medway house.

Medway Council decides planning applications for Gillingham, Chatham, Rochester, Strood and Rainham, and STG Building Control, based on Rochester High Street, inspects the work. Many single-storey rear extensions fall within permitted development; the council strongly encourages a Lawful Development Certificate to confirm it, which your builder or architect can apply for. Conservation areas and Article 4 streets in Gillingham Park, Brompton and Historic Rochester change the rules, so have your address checked before anything is drawn.

Medway is a terrace-and-semi area: in Gillingham South 85 per cent of homes were built before 1919. That means shared walls, so most extensions need Party Wall notices, and on Chatham's hillside terraces the levels and retaining walls are part of the design from the start.

Including Gillingham, Chatham, Rochester, Strood, Rainham, Maidstone, Sittingbourne, Gravesend, Dartford, Ashford, Canterbury.

How the job runs

Four months, four stages.

01

Survey and drawings

Your builder measures up, talks through what you want and either works from your architect's drawings or arranges them. Planning or permitted development is checked for your address.

02

Price and programme

Ask for a price broken down by stage and a week-by-week programme, so you know what it costs and when it happens before work starts.

03

Build and inspect

Footings, slab, walls, roof, glazing, first and second fix. Building control inspect at each stage; check the builder books every inspection.

04

Snag and sign off

A walk-round with the builder and a snag list cleared. Get the completion certificate and any warranties before you pay the final invoice.

Questions

Asked about extensions.

Do I need planning permission?+
Often not for a single-storey rear extension within permitted development limits, which depend on your house type. Larger, two-storey, listed or conservation-area work usually needs an application. Have your address checked before you accept a quote.
How much disruption is there?+
The kitchen is usually out of action for part of the build. Ask the builder how the house will be sealed off from the site, whether water and power stay on, and how much notice you'll get of anything noisy.
Can the new brick match the house?+
Nearly always. A good builder takes a sample from the house, sources a match for colour, texture and size, and lays it with the same bond and joint as the original.
