A double-storey extension adds two floors of new space to your house in one build, typically a larger kitchen or living room downstairs with an extra bedroom, bathroom or en-suite above, sharing one set of foundations and one roof.
Whatever type of house you own in Beverley, we start by looking at how a double-storey extension would fit it rather than offering a standard package. We cover HU17 and neighbouring places such as Hull, Brough and Bridlington. One named person looks after you from survey to handover, and nothing is booked until you hold our figure in writing, fixed for the work described.

Building in Beverley
Hull has large areas of Victorian and Edwardian terraces, many arranged in the city's distinctive short cul-de-sac terraces running off the main streets, plus extensive interwar and post-war estates. Beverley keeps Georgian brick houses, Wolds villages use chalk and brick, and red clay pantile roofs are common across the area. Coastal towns such as Bridlington mix guest-house terraces with bungalows.
Terraced homes often suit loft rooms and rear extensions; pantile roofs may need re-roofing with matching tiles. Bungalows commonly benefit from loft conversions, and older brick houses need repointing with a suitable mortar.
So when we survey a Beverley property for a double-storey extension, the first step is working out how it was built and what has been changed since.
Permissions for a double-storey extension in Beverley
Homes in Beverley come under the regulations for England, summarised below. We don't rely on general rules alone: we confirm the position for your address with the council before a quote goes out.
In England, a two-storey rear extension can only be permitted development if it is no more than 3 m deep, at least 7 m from the rear boundary and finished to match the house. Most double-storey and all two-storey side extensions need full planning permission.
Building Regulations approval is needed, with structural calculations for beams, foundations and the roof. The Party Wall etc. Act 1996 often applies on semi-detached and terraced houses.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
From survey to handover
A visit to your home
It starts with a survey at the property, free of charge. We check condition, access and services, ask how you want the finished result to look, and answer any questions you have about a double-storey extension.
Quote in writing
We turn the survey notes into a written quote. The price is fixed for the specification we agree, and the document sets out materials, scope and payment stages in plain language.
Plan and prepare
Before anyone starts, we confirm the programme in writing, check whether consents are required and arrange deliveries. If a skip or scaffolding on the road needs a permit, we apply for it.
On site to finish
Work goes ahead as scheduled and you deal with one contact throughout. When the last trade leaves, we clear and clean the site, talk you through what has been done and pass on any certificates and care instructions.
How we work
Frequently asked questions
Can we live at home while it is built?
Most families stay at home during a double-storey extension. The new structure is built outside first, and we only break through into the existing rooms near the end, usually one floor at a time. Upstairs, this may mean a bedroom is out of use for a week or two. We fit dust screens, protect floors and stairs, and plan any time without water or power in advance.
Is the price fixed?
Yes, for the specification we agree. Your written quote sets out exactly what is included at a fixed price. It only changes if you ask for something different, or if a problem the survey could not reasonably reveal later needs extra work. In either case we explain the change and confirm it in writing before going ahead.
Will the extension affect my neighbours?
A double-storey extension can affect neighbours' light, outlook and privacy, which is why planning departments look closely at height, depth and window positions. Side windows facing neighbours often need obscure glass. Work near a shared wall may also need party wall notices; the Party Wall etc. Act 1996 applies in England and Wales only. We talk through these points early so the design is realistic.
Is a double-storey extension better value than single-storey?
A double-storey extension usually gives better value per square metre than a single-storey one, because the same foundations and roof serve twice the floor area. The overall cost is higher, and planning can be harder because of the effect on neighbours. If you might want an extra bedroom later, building both floors now avoids a second round of disruption and scaffolding.
How much will a double-storey extension cost in Beverley?
As a guide, expect to pay £56,000–£113,000 including VAT for a double-storey extension in Beverley. That range is adjusted for Yorkshire and the Humber, which runs about 6% below the national guide. Where your project lands depends on size, materials, access and the condition of what is already there. We confirm a fixed price in writing after a free survey of your home.
