London extension construction
House extensions in London
Taska Group provides house extension construction in London for homeowners planning additional living space, a larger kitchen, improved circulation or a broader home renovation.
We review the property, extension concept, drawings, planning position, structural information, neighbour interfaces, access and desired finish before the construction quotation is defined.
Extension feasibility
The same extension type does not fit every London property
Plot width, boundaries, existing structure, drainage, roof form, access and local planning constraints affect what can be built. Early drawings or a clear concept help, but the construction scope must be based on the actual property and the information needed for approval and structural design.
Service scope
Common house extension forms to discuss
These labels describe broad configurations, not automatic planning or construction solutions.
Rear extensions
Extend into the rear plot where dimensions, boundaries, drainage, light and planning constraints allow.
Side-return extensions
Consider narrow side space alongside a London terrace and how it connects to the existing structure.
Wraparound extensions
Combine rear and side areas where the property, design and permissions support the larger footprint.
Two-storey extensions
Assess additional upper-level space with closer attention to structure, neighbours, outlook and planning.
Assessment first
What must be clear before an extension is priced?
A construction quotation needs a defined design basis. An early budget discussion and a final build scope are not the same thing.
- Existing property
Review structure, boundaries, levels, drainage, services, access and the areas that connect to the extension.
- Drawings and approvals
Confirm which surveys, drawings, planning decisions and Building Regulations information exist.
- Structural information
Identify engineer details for openings, beams, foundations and other structural work.
- Level of finish
Define shell, first-fix, second-fix, kitchen, flooring, decoration and external-work boundaries.
Project needs
What can a well-planned extension change?
Larger kitchen and dining space
Create a different relationship between cooking, dining and the garden.
Additional living area
Add a family, work or flexible room around the household’s actual needs.
Improved circulation
Reconsider internal routes and openings as part of the extension design.
Whole-home renovation
Coordinate the new structure with connected rooms and finishes.
Scope decisions
Decisions that affect the extension quotation
Scope clarity is especially important when design, approvals, specialist information and finishes meet.
Design stage
State whether the project is an idea, has measured drawings, has planning approval or is ready for construction information.
Professional roles
Confirm the architect, planning, structural engineering and Building Control arrangements.
Site constraints
Record access, parking, storage, neighbours, party walls, occupied areas and working-hour limits.
Interior completion
Agree kitchen, bathroom, joinery, flooring, tiling and decorating boundaries.
Direct answer
Can Taska Group help before the house extension is ready to build?
Yes. Architects, planning and structural engineers can be arranged or coordinated. The right starting point depends on what information already exists. Taska Group should not treat an early concept as a final construction scope, so the next step is to identify the missing design and approval inputs.
Who we work with
House extensions for domestic, managed and commercial property
Homeowners
Discuss house extensions for an occupied or vacant London home, with access and retained areas explained.
Landlords
Define the property condition, required outcome, access arrangements and product or finish approvals.
Managing agents
Share the approval route, site contacts, occupied areas and handover information for managed property.
Commercial clients
Explain how the premises are used and any access, operational or sequencing constraints.
Planning and neighbour matters
Permitted development, planning, Building Regulations and Party Wall duties are separate checks
Planning Portal explains that some extensions can be permitted development only when specific limits and conditions are met. Building Regulations still address construction standards, and Party Wall duties may apply to boundary, wall or excavation work. The applicable route must be confirmed for the property; no blanket permission claim is made.

Frequently asked questions
House extensions in London FAQs
For an answer based on your property, share photographs and the information described above.
Which house extension types do you build?
Rear, side-return, wraparound and two-storey extension ideas can be discussed, subject to the property, design, approvals and structural information.
Can you arrange an architect or structural engineer?
Yes. Architects, planning and structural engineers can be arranged or coordinated as confirmed parts of Taska Group’s service.
Do all extensions need planning permission?
No single answer applies. Some work can meet permitted-development rules, while other work requires planning permission. Limits, conditions and local constraints must be checked.
Do Building Regulations apply?
Extension construction normally requires Building Regulations consideration even where planning permission is not required. Confirm the route with the relevant professionals and authority.
Will I need a Party Wall agreement?
It depends on boundary, party-wall and excavation work. GOV.UK guidance explains the kinds of work that require notice. Obtain project-specific advice.
Can a kitchen be included in the extension?
Kitchen installation can be coordinated where included in the agreed scope. Product, worktop and service responsibilities should be defined.
Can you work while the house is occupied?
Occupancy can be discussed, but access, separation, services and disruption need to be assessed for the actual construction sequence.
Are quotations and site visits free?
Yes. Quotations and site visits are free, although a build quotation may depend on drawings, approvals and structural information being available.
