Extensions and Complete Refurbishment

Work is about to commence on the extension and complete refurbishment of this three-bedroom detached property, transforming it into a spacious four-bedroom, two-bathroom family home.

A major part of the project is a dramatic alteration to the rear of the property, which will involve removing a previous extension which had been poorly planned and did not make the best use of the available space. The rear of the property will be completely remodelled to create a large, open-plan Kitchen, Dining and Family Area, designed to become the real heart of the home and provide a much better connection between the house and garden.

The proposals have been developed very much with family life in mind, with the new layout also incorporating a Gym, Play Room, Boot Room, Utility Room and ground-floor Shower Room, together with improvements and alterations throughout the existing house.

Alongside the extensions, the property will undergo a complete refurbishment and modernisation, bringing the accommodation up to date while creating a practical, comfortable and flexible home that should work extremely well for the family for many years to come.

We’re really looking forward to seeing this one take shape. We’ll be calling in as the works progress and hope to share further updates along the way, followed by the finished transformation once complete.

A well thought out project for a lovely couple and their family, and one we’re looking forward to watching develop.

If you’re thinking about a project and want to talk it through, we’d love to hear from you — the Initial Consultation is free, and there’s no pressure to commit.

KJP Architecture - Explainer Series 4

So, you have checked the PDR, and your extension does not comply, if it is because its over the limit of 3.0m for terraced and semi-detached properties or 4.0m for detached properties, then you could apply for Prior Approval.

• Prior Approval applies to larger single-storey rear extensions.

A “larger” extension is defined as one that extends beyond the rear wall of the original house by:

• more than 4 metres and up to 8 metres for detached houses; and
• more than 3 metres and up to 6 metres for all other houses.

If you wish to build an extension of this size under Permitted Development Rights, you must apply to the local authority for Prior Approval.

As part of this process, the local authority will notify adjoining neighbours and invite them to comment on the proposal.

If any concerns or objections are raised, the local authority must then assess whether the extension would have an unacceptable impact on the amenity of neighbouring properties.

Based on this assessment, they will determine whether the proposal can proceed.

If your proposal fails to comply with PDR and Prior Approval, then your only option is to apply for Planning Permission.

KJP Architecture - Explainer Series 3

So, you have decided you do want an extension — and you are clear on what you are trying to achieve.

The next step is understanding what type of planning approval is required and which route is right for your project.

What do you need for a house extension?
Many homeowners assume extensions always require Planning Permission.
Sometimes that is correct — but many fall under Permitted Development.

What is Permitted Development?
Permitted Development (PD) is a set of rights granted by the UK Government that allow certain works to be conducted without applying for full planning permission.

Think of it as a fast-track route — fewer delays, less red tape — if you meet the rules.

•Permitted Development Rights (PDR)
Some extensions and loft conversions can proceed without planning permission, but only if they meet strict limits on:
Size and projection
Height and eaves level
Distance to boundaries
Materials
Percentage of garden built over

If just one of these limits is exceeded, planning permission is usually required.

There is detailed technical guidance available from the Government, but interpretation is key — small measurement differences can change everything.

Where an extension complies with PDR, we always recommend applying for a Certificate of Lawful Development.

This provides written confirmation that the works are lawful — invaluable for future sales, remortgages, and general peace of mind.

Certificate applications typically take around 6 weeks.

• When PDR Do Not Apply

Permitted Development Rights can be restricted or removed if:

The property is in a Conservation Area
The building is listed
It is a flat or maisonette
Previous extensions have already used up allowances
An Article 4 Direction or planning condition applies

In some cases, the Prior Approval route may still be available.
Understanding which route applies at the outset can save time, cost, and frustration later.
If you are unsure, that is exactly what we are here for.

A true self build
One of our favourite projects — the complete transformation of a 1960s bungalow into a refined contemporary two-storey residence, designed to respond to its setting and take full advantage of the property’s far-reaching views.

The project establishes an entirely new architectural identity through carefully balanced proportions, clean contemporary detailing and a restrained palette of modern materials.

A defining feature is the dramatic feature window to the master bedroom, conceived as a strong architectural element within the elevation. The generous area of glazing floods the room with natural light while framing the extensive views beyond and creating a strong visual connection between the house and its surrounding landscape.

The glazing forms an integral part of the overall composition, helping to break down the scale of the new two-storey form while giving the property its distinctive contemporary character.

Internally, the accommodation was comprehensively reconfigured to create generous, light-filled living spaces, improved circulation and a much stronger relationship between the principal rooms and the outlook beyond.

What makes this project particularly special is that it was a true self-build. The clients were fully involved throughout the construction process, taking an active role in bringing their ideas, ambitions and ultimately their dream home to life.

The result is a substantial architectural transformation — taking a modest mid-century bungalow and reinterpreting it as a distinctive, elegant and highly individual contemporary family home.

KJP Architecture - Explainer Series 2

• Natural light matters
Light can make or break an extension - Consider:
Orientation (sun path)
Window & door positions
Rooflights or lanterns
How light reaches existing rooms

Good daylight design makes spaces feel bigger, brighter, and more usable.

• Budget (and contingency)
As a rough guide, many extensions are around:
£2,000–£3,000+ per m² (build cost only)

Also allow for:
Professional fees
Planning & Building Regulations
Services & finishes
A sensible contingency

Unexpected issues often arise once work starts — planning for them reduces stress later.

• Learn from neighbours
If nearby properties have already extended, call round and ask how their project went.

Ask about foundations
Any Drainage issues
What were the ground conditions like
Any problems obtaining materials
Who was their builder and would they recommend them

Local knowledge can be invaluable early on.

• Impact on neighbours
Key considerations:

Loss of light
Overshadowing
Overlooking & privacy
Scale and massing
Proximity to boundaries

These matter for planning applications and permitted development.

A simple rule of thumb, ask yourself:

Would you be happy if your neighbour built the same extension next door?

If the answer is no — it’s worth revisiting the design early.

If you’re at the

“where do I even start?” stage — we’re happy to help.

A Contemporary Rear Extension

This stylish rear extension transforms the original property with a light-filled, open-plan living space.

This extension features a dramatic full-height glazed apex window and large aluminium-framed sliding doors, seamlessly connecting the interior with the outdoor patio.

The exterior is finished in crisp white render, with anthracite grey detailing to match the new windows and doors, creating a clean and contemporary aesthetic.

High-level rooflights further enhance natural light, while the modest scale of the addition ensures it integrates comfortably with the original architecture.

Internally, this provides a spacious area for a kitchen, dining and living space, perfect for modern family living and entertaining, which totally transforms the original home.

The clients were super impressed with the contractors on site and would recommend them to anyone thinking of having something similar built.
