Small Space, Big Possibilities

There’s something special about terraced homes. From their timeless character to their cosy charm, they have stood the test of time across the UK. But when your lifestyle outgrows your layout, a kitchen extension on your terraced house can make all the difference. We are expert extension builders, specialists in transforming compact spaces into spacious, light-filled family hubs without compromising on style or heritage. We cover Surrey, London, and all nearby areas of the M25.

With a people-first approach and a focus on exceptional quality, we help homeowners unlock their home’s true potential—one perfectly designed extension at a time.

Why Extend the Kitchen in a Terraced House?

For many terraced homes, the kitchen is often small and tucked away at the rear. A kitchen extension provides the opportunity to:

• • Create an open-plan kitchen-diner
  • Improve natural light with skylights or bi-fold doors
  • Increase property value (by as much as 20% in some cases)
  • Better accommodate growing families or entertaining guests
  • Enhance flow and functionality throughout the ground floor

A kitchen extension is one of the most impactful upgrades a terraced homeowner can make. It combines aesthetic transformation with a dramatic improvement in how the space works day-to-day.

Our Process: Tailored from Start to Finish

Every kitchen extension project starts with a detailed consultation and home assessment. We take the time to understand your lifestyle needs, assess site access, and navigate any structural or regulatory challenges.

Our full-service offering includes:

• • Initial Consultation & Site Survey: We evaluate your existing space, access, and opportunities for structural changes.
  • Planning Permission or Permitted Development Advice: We determine if your extension qualifies under permitted development or needs planning permission and manage submissions accordingly.
  • Party Wall Agreements & Neighbour Consultation: We handle all legal obligations involving adjoining properties.
  • Material Sourcing & Specification: We help you select finishes that blend style, durability, and budget.
  • Construction, Project Management & Aftercare: Our team ensures on-time, quality-focused execution from the first brick to the final clean-up.

With KT5 Construction, you’ll never feel left in the dark. We manage every stage with clear communication and an unwavering commitment to excellence.

Permitted Development vs Planning Permission for 

Not all terraced house kitchen extensions need full planning permission. If your extension:

• • Extends no more than 3 metres from the rear wall (or 6 metres with prior approval)
  • Takes up less than 50% of your garden area
  • Is no higher than 4 metres
  • Doesn’t face the highway or overlook neighbours excessively

…you may be covered under permitted development rights. That said, location matters. Homes in conservation areas or subject to an Article 4 Direction may need full permission.

KT5 Construction will help you determine the correct route and handle the paperwork on your behalf, ensuring your project progresses without costly planning delays.

Important Considerations for Terraced House with a Kitchen Extension

1. Lighting & Ventilation

Terraced homes are often narrow, which can make middle rooms dark. We use architectural strategies like skylights, wide doorways, and internal windows to maintain brightness and airflow throughout.

2. Party Wall Agreements

Since terraced homes share walls, any structural work may require a party wall notice and possibly an agreement. We coordinate with your neighbours and surveyors to ensure compliance and avoid disputes.

3. Structural Constraints

Older terraced homes may need underpinning, steel beams, or drainage upgrades. Our structural engineers and builders ensure that all support elements are properly integrated.

4. Access & Logistics

Rear access is limited in many terraced properties. We plan carefully to minimise disruption and keep your home safe and clean during work.

5. Budgeting Smartly

A kitchen extension can cost between £15,000 and £60,000 depending on size, materials, and specifications. We provide fully itemised quotes and help you factor in a 10% contingency to cover unexpected issues. Our budgeting process includes clear timelines, cost breakdowns, and payment schedules.

FAQs: Terraced House with a Kitchen Extension

1. Can I build without planning permission?

Yes, if it meets permitted development criteria. We’ll advise and apply for a certificate of lawful development if needed.

2. Will I lose garden space?
Yes, but we design extensions that balance indoor gain with outdoor enjoyment. You can also integrate a patio or rear landscaping.

3. Can I live in my home during the build?
Most of the time, yes. We’ll work with you to reduce disruption, set up temporary cooking areas, and protect interiors.

4. Will it add value?
Absolutely. A kitchen extension is one of the best ways to add both lifestyle value and market appeal.

5. What about building regulations?
All work is carried out to meet current UK building regulations covering structure, insulation, plumbing, ventilation, and more.

6. How long will it take?
Most single-storey kitchen extensions take between 8 to 12 weeks depending on complexity. We’ll provide a project schedule before we begin.

7. Can I extend a listed terraced home?
Possibly. You’ll need planning permission and listed building consent. We work closely with conservation officers to maintain heritage features.
